Subject: [Matplotlib-users] Single Colorbar for multiple subplots

I modified matplotlib to let you do this by passing an array of axes to the ax argument of colorbar.  It's in the git master branch but that has other bugs so you may not want to use it yet.  

But the way to do this with older releases is to make the axis you want to put the colorbar in manually (cbax=fig.add_axes) with the correct position and then pass cbax to colorbar as the argument to the parameter cax.  Of course you may need to make the other subplots smaller prob using the subplots_adjust method if the figure. 

Cheers.  Jody

I do exactly this as well (but on linux)!

The symptoms your are describing sounds like the GUI event loop is not
being spun behind the scenes (see
https://github.com/matplotlib/matplotlib/pull/4779 for some draft text at
explaining how all of that works).  Have you tried doing `%matplotlib` is
IPython?

GUI frameworks tend to require they be on the main thread.  Which backend /
gui framework are you using here?

In general you will have to arrange things so that the main thread owns the
GUI windows + plotting and the child threads own the computation.

Fabian,

The `Circle` artist is sized in data-space so it _should_ changes sizes as
you zoom.

If you just want to show markers sized in _screen_ space use `scatter`

    sc = ax.scatter([a.x for a in atoms], [a.y for a in atoms],
s=[radii[a.number] for a in atoms])

should do the trick.

Do you have a file called `tempfile.py` in the directory you are running
the script from?

The issue is that the module `tempfile` (which should be coming from the
standard library) is reporting that it does not have an expected member
(TemporaryFile).   If you are shadowing that module with a local file you
will see exceptions like this.  The other option is that you python
installation is broken.

It is likely there things are not being garbage collected due to either a
missed reference surviving or the circular references between the various
objects is delaying gc from collecting them (I do not recall the details
exactly off the top of my head, but running gc manually with more
generations may help).

However, if you are embedding in a GUI you are probably better off just
doing the embedding directly (and skipping `pyplot` entirely, see
https://matplotlib.org/examples/user_interfaces/embedding_in_tk.html ).
Re-using the Figures / Axes / Artists to update the data (rather than
starting from scratch every time) may also prevent the memory leaks _and_
give you a performance boost.

The devdocs are built against current master (not 2.0.x ).

That PolygonSelector was added very recently (
https://github.com/matplotlib/matplotlib/pull/8403 ), is currently only on
the master branch, and will be included in the upcoming 2.1 release.

Stefan,

On a quick skim that does not look wrong.

I would not use globals and have the callbacks be methods on
your BOStrab_Fahrzeugeinschraenkung class.

Szymon,

We have a section dedication to image, contour, and field plots:

http://matplotlib.org/gallery.html#images_contours_and_fields

Start there and let us know what specific issues you're having in a very
minimal and easily copy-pastable dataset.

Subject: [Matplotlib-users] Plotting dates on the y-axis of a contour
 map/ hovmoller
In-Reply-To: <1499714810715-48081.post@n5.nabble.com>

The contour function can be called in many forms.

Without your data, it's hard to see exactly what's going on, but it looks
like you're using the contour(Z, V) form.

I recommend using the contour(X, Y, Z) form. Passing Y as an array of
datetime-like object should "just work".

If it doesn't, boil this example down to something we can copy-paste into a
terminal/notebook and mess around with. A 5 x 5 array for your Z values and
some of the dates in the format you currently have them should suffice.

This sounds like something you'd want to use yt or mayavi for. While MPL
has basic 3D capabilities (e.g., scatter, line, and surface plots), taking
cuts of volumes is definitely out of our scope unless you've pre-computed
everything.

Ahlam,

I'm by no means an expert on compiling this libraries on any OS. If you
don't need the absolutely bleeding-edge versions, I would use conda to
install them.

For instance
conda install geopandas --channel=conda-forge

automatically grabs and installs a pre-compiled GEOS binary to support the
geopandas library

Hi Thomas,

thank you for answerring. I have already developed further. Here is my
current code.

def PlotFrame(self):

    self.fig = Figure (figsize=(5,4), dpi=100)
    self.ax = self.fig.add_subplot(111)
    self.ax = self.fig.add_subplot(111) #fuer 2d-Plot
    self.ax.set_title('Definition der LRUGL')
    self.ax.set_xlabel('Fahrzeugbreite y [mm]')
    self.ax.set_ylabel('Fahrzeughoehe z [mm]')
    self.ax.axis([-2000,2000,0, 5000])
    self.ax.grid(True)

    self.canvas = FigureCanvasTkAgg(self.fig,self)
    self.toolbar = NavigationToolbar2TkAgg(self.canvas,self)
    self.toolbar.update()
    self.plot_widget = self.canvas.get_tk_widget()
    self.plot_widget.pack(side=tk.TOP, fill=tk.BOTH, expand=1)
    self.toolbar.pack(side=tk.BOTTOM, fill=tk.BOTH, expand=1)

    self.ax.plot(np.zeros(100))

    def onMouseMove(event):

        self.ax.lines = [self.ax.lines[0]]
        if event.xdata and event.ydata: # python3 often has None
            self.ax.axhline(y=event.ydata, color="k") #(y=event.ydata,
color="k")
            self.ax.axvline(x=event.xdata, color="k") #(x=event.xdata,
color="k")
        self.canvas.show()

    self.canvas.mpl_connect('motion_notify_event', onMouseMove)
    self.canvas.show()

    def fig_ax_request():
        publish('FIG,AX',self.fig,self.ax)

    subscribe('REQUEST_FIG,AX',fig_ax_request)


def DrawPlot(self):

    def test_plot():

self.ax.imshow(np.random.normal(0.,1.,size=[1000,1000]),cmap="hot",aspect="auto")
        self.fig.canvas.draw()

    self.buttonAAA['command'] = test_plot

    def get_fig_ax(fig,ax):
        self.fig = fig
        self.ax = ax

    subscribe('FIG,AX',get_fig_ax)
    publish('REQUEST_FIG,AX')


Now i have a table for input and an embedded diagram in tkinter canvas.
This code above is only for testing. I want the functionality that i can
write values in the table and let it simultanously paint into
matplot-Canvas. Hav eyou some suggestion or imrpovements to do that ?


 Best regards from Stefan

Hallo,

You are not allowed to create the directory /include as a normal user, 
because it is under / which is owned by root. If you really want to 
install it to this location you need to become super user first.
So the last `make install` should be an `sudo make install`.

But I would also stick to Paul Hobson's solution of using conda [1] or 
in your case homebrew [2].

[1] https://www.continuum.io/downloads
[2] https://brew.sh/

Best regards,
Julian

As a note: the `/include` came about due to a mistake with the environment
variables. So, the fact that a `sudo make install` even works is just
papering over the original mistake.

Another fantastic tool is glumpy: https://glumpy.github.io/ (but I am not
familiar enough with the API to know how to do volumetric displays). vispy
is another possibility, but I am unsure of its current status (it went
silent about a year ago).

Subject: [Matplotlib-users] Problem of memory leak using

The stackoverflow posting notes that mpl v1.1.1 was used, which is 5 years
old. I am pretty sure we have made a lot of memory leak fixes since then. I
noted as such on SO.

Here is a notebook that illustrates how to work with volumetric data in
Plotly:
http://nbviewer.jupyter.org/github/empet/Plotly-plots/blob/master/Plotly-Slice-in-volumetric-data.ipynb
<http://nbviewer.jupyter.org/github/empet/Plotly-plots/blob/master/Plotly-Slice-in-volumetric-data.ipynb>  
Another possibility is to define a slice in a volume as a triangulated
isosurface, via skimage.measure.marching_cubes.

main thread is owning the GUI. My Python installation runs Tkinter version
: 8.5 and this happens with Tkinter. I ran the same code on another machine
which used another GUI framework(not sure what was it) and it went well. So
I guess something is wrong with Tkinter.

Subject: [Matplotlib-users] tuple-marker in style sheet
Message-ID: <92b44729-f13e-d05b-80c2-db77d87f28ee@gethmann.org>

Hallo,

is it possible, and if so how, to define a marker with the tuple 
definition (numsides, style, angle) [1] inside a style sheet (or 
matplotlibrc)?

For normal markers I use the axes.prop_cycle like
```
axes.prop_cycle: cycler("marker", ["x", "+", "1"])
```
. If I now want to insert a tuple like marker,
```
axes.prop_cycle: cycler("marker", ["x", "+", (5, 2, 1)])
```
  then it is being transformed into a string `"(5, 2, 1)"`.
If I don't use parenthesis like in other tuple values in the 
matplotlibrc (e. g. `#lines.dashed_pattern : 2.8, 1.`[2]) then it is 
interpreted as three different marker styles which do not exist [3].

[1] http://matplotlib.org/api/markers_api.html
[2] http://matplotlib.org/_static/matplotlibrc
[3] in my example: `ValueError: Unrecognized marker style 5`


Many thanks,

Julian

This *might* be fixed in master. Which version of matplotlib are you using?

Now I also tested the current master branch from github, but I also get 
the same error message if I use parenthesis.
Do you know of which issue you were thinking of?

Hmmm, might be an issue with respect to specifying custom dash styles. It
had a similar problem to this.

For the longest time, I have avoided trying to combine Basemap and mplot3d
because I knew that they both predated the transforms system and that they
wouldn't be able to properly work together. However, today, I looked at the
problem differently for some reason and realized that it might actually be
possible for them to work together in a hacky sort of way.

```
from mpl_toolkits.basemap import Basemap
from mpl_toolkits.mplot3d import axes3d, art3d
from matplotlib import pyplot as plt

fig, ax = plt.subplots(subplot_kw=dict(projection='3d'))
bm = Basemap(projection='merc', lat_0=57, lon_0=-135, resolution='l',
                        llcrnrlon=-130, llcrnrlat=20, urcrnrlon=-65,
urcrnrlat=55)

map(art3d.patch_2d_to_3d, bm.fillcontinents(color='wheat',
lake_color='aqua'))
art3d.line_collection_2d_to_3d(art3d.bm.drawcoastlines())
art3d.line_collection_2d_to_3d(bm.drawstates())
art3d.line_collection_2d_to_3d(ret4 = bm.drawcountries())

plt.show()
```

Still a bit buggy. The lakes, states and countries aren't showing up, but
it is a start!

Hello everybody,

I have this figure done by a colleague quite a while ago in matplotlib:

https://image.ibb.co/cxGKSF/tst0.png

Unfortunately, I no longer have contact with my colleague to ask the particular colormap she used in matplotlib. I have looked through the gallery at https://matplotlib.org/examples/color/colormaps_reference.html but I am unable to find that colormap she used there.

Can anybody recognize the colormap she used in that plot?

Thank you!
Best, Kris

Hi Kris,

That one is called ?jet?, though it looks like she applied a bit of 
a normalization to it to move the (green) center to lower values?

https://matplotlib.org/users/colormapnorms.html  (see the last 
subsection: ?Two linear ranges?)

Cheers,  Jody

Not jet, it doesn't go through cyan. Looks more like coolwarm, to me, or
maybe RdYlGn_r (but the yellow isn't right, either...).

I am also not completely convinced it was made in matplotlib. The 3d plot's
projection isn't the same as mplot3d's projection.

Hi all,

I agree with Ben that it does not look like jet to me: the bright light 
blue seems to be missing. FWIW, "Spectral" (with a capital S) might be 
the closest colormap among the built-in ones in Matplotlib, but it is 
still more ?pastel-ish? than Kris? example.

Best,
Adrien

This image has pretty clearly been converted to CMYK hence the dullness. Pretty convinced that's what jet looks like after a CMYK conversion.

See:

https://gist.github.com/jklymak/744db8cc538e5757ecc4eb4977bff3a3

CMYK conversion was done in Illustrator.

You could still argue that matplotlib?s ?jet? gets darker at the 
high reds and low blues, and maybe the cyan is more bright.  But you 
have to be pretty careful w/ CMYK conversions because it depends on the 
profiles used etc etc.  I?d buy the argument that this is a matlab jet 
versus a matplotlib jet, but I think most of the perceived difference is 
because a CMYK conversion happened somewhere along the way.

Cheers,   Jody

PS, I note the image *says* that it is RGB, but then my converted image 
also says the same thing.

The CMYK converted jet still has a bright yellow in there that is not in
the one showed by Kris at all.

Thank you Jody, I did not know that CMYK conversion could alter colors 
that much; that is interesting.

Ben, maybe my cheap screen is tricking me here, but I would have say 
that what is still missing in the CMYK conversion is the cyan/bright 
blue part, not the yellow one. Anyway, as Jody wrote, it might just be a 
matter of CMYK profile, doesn?t it?

Best,
Adrien

Yes, there is also still the cyan. I am doubtful that just having a
different profile would be enough to change this. I think either RdYlGn_r
or coolwarm is a lot closer than jet put through a cmyk conversion. I am
going with the philosophy of the simplest model that explains the most
amount of the data observed. A cmyk conversion isn't out of the question
because many publications do that conversion. But if that was the case,
then putting RdYlGn_r or coolwarm through CMYK conversion might actually
bring it closer to your example than CMYK converted jet is.

Also, keep in mind, I am still not convinced that this is even matplotlib
in origin due to certain features of the 3d plot (I am the maintainer of
mplot3d). I don't know if it looks like matlab's version, though, as I
don't have experience with it.

Hi,

Thanks for the replies. I use MATLAB so I am familiar with jet; but the colors in my colleague's plot looked too "pastelized" that I had my doubts, and finally decided to ask.

Best, Kris

Subject: [Matplotlib-users] Why the V parameter in
 matplotlib.axes.Axes.contour must be increasing?
Message-ID: <CANO68EMkW6me2uWouDrR4uAgcy2+msLGEYEVquobW_FcfwT79w@mail.gmail.com>

Hi,

https://matplotlib.org/api/_as_gen/matplotlib.axes.Axes.contour.html says
the contour function accept a vector parameter V which must be in
increasing value. But the contour function in MATLAB does not have this
restriction.

I understand the underlining implementation of these two functions could be
very different. I want to understand what is the purpose of this
restriction, and if it possible to create a contour image the same as
MATLAB does by using contour with V = [0 0]?


Regards,
David

Probably because nobody noticed that discrepancy before. I'd imagine it
would be fairly simple to apply a sort to the list of values within the
function itself. The underlying contouring implementation assumes a
monotonically increasing set of contour levels, and I would imagine that
MATLAB's version does too -- just that they sort the contour levels for you.

At the moment, I don't see any reason why we couldn't do that, too.

Cheers!
Ben Root

Subject: [Matplotlib-users] Setting rcParams ps.fonttype = 42 yields
 unreadable eps
Message-ID: <1502901117295-48197.post@n5.nabble.com>

I created a bug report at
https://github.com/matplotlib/matplotlib/issues/9044, but in the mean time I
am keen to get some help from this user group.

I'm trying to create an eps output from matplotlib 2.0.2 with editable text
(truetype). I've used the settings:

import matplotlib
matplotlib.rcParams['ps.fonttype'] = 42

Which yields a file size increase from 19Kb to 1.2Mb, but no software (MacOS
Preview, or Adobe Photoshop 2017) can read the file. For those interested I
have attached both `*.eps` output files in the zip archive at the link at
the top of the page.

The truetype (ps.fonttype = 42) file contains the following, and `DejaVu
Sans` doesn't appear to be installed (checking the MacOS Font Book
application):
...
%!PS-TrueTypeFont-1.0-2.22937
%%Title: DejaVu Sans
%%Copyright: Copyright (c) 2003 by Bitstream, Inc. All Rights Reserved.
Copyright (c) 2006 by Tavmjong Bah. All Rights Reserved. DejaVu changes are
in public domain
%%Creator: Converted from TrueType to type 42 by PPR
...

A demo script to reproduce the problem is:

import matplotlib
from matplotlib import pyplot as plt
fig = plt.figure(dpi=100, facecolor='w', edgecolor='w')
ax1 = plt.subplot2grid((2,2), (0, 0), rowspan=2, facecolor='w')
ax2 = plt.subplot2grid((2,2), (0, 1), facecolor='w')
ax3 = plt.subplot2grid((2,2), (1, 1), facecolor='w')
matplotlib.rcParams['ps.fonttype'] = 3
fig.savefig('demo-type3.eps') <- Opens fine
matplotlib.rcParams['ps.fonttype'] = 42
fig.savefig('demo-type42.eps') <- Errors on all applications I have tried

System config:
  * Operating System: MacOS 10.11.6
  * Matplotlib Version: 2.0.2-py27_1 (conda-forge)
  * Python Version: 2.7.13-1 (conda-forge)
  * Jupyter Version (if applicable): NA (1.0.0-py27_0 conda-forge)
  * Other Libraries: NA (can provide if required)
  * Installation path: conda (conda-forge channel)

Happy to hear any tips as to how to get around this issue.

Cheers,

P

Hi David,

I?ve definitely run into this, to my annoyance.

Do you think you can open an issue on 
[GitHub](https://github.com/matplotlib/matplotlib/issues)?  If you 
don?t want to, I?m happy to do it.

With respect to one contour at zero, its easier than Matlab:

ax.contour(X, np.array([0.]))

works for me?

Cheers,

Hi Jody,

I confirm that giving V = [0] to contour function in matplotlib gives me
the same image as using V = [0 0] in MATLAB.

Do you think it is a bug in matplotlib, or it is just a conscious design
decision? I do not have much knowledge of math behind this, so for me it is
just a restriction on parameter values.


Thanks,
David

Subject: [Matplotlib-users] Setting rcParams ps.fonttype = 42 yields
 unreadable eps
Message-ID: <1502900616633-48196.post@n5.nabble.com>

I created a bug report at
https://github.com/matplotlib/matplotlib/issues/9044, but in the mean time I
am keen to get some help from this user group.

I'm trying to create an eps output from matplotlib 2.0.2 with editable text
(truetype). I've used the settings:

import matplotlib
matplotlib.rcParams['ps.fonttype'] = 42

Which yields a file size increase from 19Kb to 1.2Mb, but no software (MacOS
Preview, or Adobe Photoshop 2017) can read the file. For those interested I
have attached both `*.eps` output files in the zip archive at the link at
the top of the page.

The truetype (ps.fonttype = 42) file contains the following, and `DejaVu
Sans` doesn't appear to be installed (checking the MacOS Font Book
application):
...
%!PS-TrueTypeFont-1.0-2.22937
%%Title: DejaVu Sans
%%Copyright: Copyright (c) 2003 by Bitstream, Inc. All Rights Reserved.
Copyright (c) 2006 by Tavmjong Bah. All Rights Reserved. DejaVu changes are
in public domain 
%%Creator: Converted from TrueType to type 42 by PPR
...

A demo script to reproduce the problem is:

import matplotlib
from matplotlib import pyplot as plt
fig = plt.figure(dpi=100, facecolor='w', edgecolor='w')
ax1 = plt.subplot2grid((2,2), (0, 0), rowspan=2, facecolor='w')
ax2 = plt.subplot2grid((2,2), (0, 1), facecolor='w')
ax3 = plt.subplot2grid((2,2), (1, 1), facecolor='w')
matplotlib.rcParams['ps.fonttype'] = 3
fig.savefig('demo-type3.eps') <- Opens fine
matplotlib.rcParams['ps.fonttype'] = 42
fig.savefig('demo-type42.eps') <- Errors on all applications I have tried

System config:
  * Operating System: MacOS 10.11.6
  * Matplotlib Version: 2.0.2-py27_1 (conda-forge)
  * Python Version: 2.7.13-1 (conda-forge)
  * Jupyter Version (if applicable): NA (1.0.0-py27_0 conda-forge)
  * Other Libraries: NA (can provide if required)
  * Installation path: conda (conda-forge channel)

Happy to hear any tips as to how to get around this issue.

Cheers,

P

Message-ID: <1503043348317-48236.post@n5.nabble.com>

Hi, i have a matplotlib graph and i want to insert several lines or linesets
to the graph. Until here no problem. I also want to see curser lines by
adding onMouseMove-Event through 'motion_modify_event'-declaration. My
problem is, that only the first drawn line is visible after mmoving the
mouse on the graph. When the graph is only loaded, everything is visible,
but by moving the mouse the second plot will be invisible.I dont know, whats
the problem. THis is my code.def PlotInput(self):     self.fig = Figure

subscribe('DRAW_FIRST', fig_ax_request)The subscribes get lists to fill the
graph. The first  expression updates the graph when data already exists in a
gui table. The second expression fills the graph by loading a file. So the
parameters "x","y","x2" are lists.

Thanks for the respone.  Sadly, I can?t get anything useful out of the doc.  And %matplotlib doesn?t help, same effect.

This is very frustrating.  I don?t know how to debug this.  It?s just a ?black box?, I do what I?m ?supposed to?, doesn?t work.

Help appreciated!

I do exactly this as well (but on linux)!

The symptoms your are describing sounds like the GUI event loop is not being spun behind the scenes (see https://github.com/matplotlib/matplotlib/pull/4779 for some draft text at explaining how all of that works).  Have you tried doing `%matplotlib` is IPython?

David,

Please subscribe to the mailing list so you can post un-moderated.

Which backend are you using?

If you get a window up and then do `fig.canvas.flush_events()` will it
update?

If you do `plt.ioff()` and then `plt.show()` does it work?

Tom

Hi,

* Just subscribed to list.

* Backend: mpl.get_backend() = ?Qt5Agg?.  I am not committed to this if another one will work.

* ?If you get up a window:? I start ipython within emacs (the GNU win32 build, not cygwin), and do figure(1), a figure window appears, but nothing renders, and window title bar says ?Not responding.?  If I plot something, it doesn?t appear.

fig is not defined, by default.  I can do fig=gcf().  Then fig.canvas.flush_events() has an interesting effect ? the plot appears, but then window title still says ?not responding? and when I hover the mouse over the figure window it becomes Windows? spinning blue circle (the busy symbol, like Mac?s spinning beachball).

?control? is returned to ipython.  I can continue to execute commands there.

* At this point, plt.ioff() doesn?t seem to do anything.  plt.show() does ? ?not responding? disappears, the figure window works like normal.  Buttons on it work.  But the ipython window is ?frozen? no In[] prompt.

OK so this seems like a lot of information.  Maybe we can make progress?

Dave

That is at least all consistent!  The issue as that for what ever reason
the input hook is not being set up correctly (which is what lets the GUI
event loop spin and process events while the terminal waits for you to
type).  With `plt.ion()` the terminal is blocking the process waiting for
you to type (which is why the window is not responding), with `plt.ioff()`
when you do `plt.show()` the GUI event loop is blocking the process (which
is why it works, but you don't get the next prompt back until you close the
plot window).  Again, see https://github.com/matplotlib/matplotlib/pull/4779
for a longer pass at explaining how this all works (and I would appreciate
feed back about where it does not make sense!).

Try using `tkagg` as the backend, the integration between python and tk in
a bit tighter (because it is done in the cpython source).

Which version of IPython and matplotlib are you using (and are you sure
that elpy is using the versions you think it is?)?

are you using `(elpy-use-ipython)` or just hacking the python executable
path?

You are siting at a very interesting intersection of technology here
(emacs + python + GUI + windows).  It might make sense to ask either on the

Message-ID: <87r2w6jjwr.fsf@dell-desktop.WORKGROUP>


Hi,

Sorry for breaking the thread, I have just subscribed to the list and I
don't know how to respond to a message that predates my subscription.  I
hope this messages makes its way.

I believe I have a similar setup (Windows + emacs + Qt5Agg, python 3.5
and matplotlib 2+).  I also see freezes when starting ipython from
within emacs.

The way I work around that is by using org-mode and ob-ipython
(https://github.com/gregsexton/ob-ipython).

To work with matplotlib, I do the following:

1 - Open my org file, which starts with something like:
,----
| #+PROPERTY: header-args :eval no-export :session Python
| 
| #+NAME: py-startup-0
| #+BEGIN_SRC ipython :results silent :exports none
| # %% Standard imports
| # General
| import os
| import sys
| import re
| import matplotlib as mpl
| mpl.use('Qt5Agg')
| #+END_SRC
`----

2 - Execute the source block (move point at the beginning of the
"BEGIN_SRC line" and C-c C-c)

I then get a warning about the interpreter which I ignore.  Note that it
sometimes hangs at that point, in which case I use C-g.

3 - The *Python* buffer then contains the ipython session, in which I
can use matplotlib: I get not freezes and calls do not block the ipython
instance.  Note that I have to run `plt.ion()` once to get matplotlib
figures to show up.

4 - I usually write most of my code in org-mode anyway, but after
running the source block I can open any .py file and work with it ignoring
the org-mode part.

For completeness, my emacs init file contains the following:
,----
| (when (eq system-type 'windows-nt)
|       (progn
|         (setq python-shell-interpreter-args "--simple-prompt -i")
|         (setq ob-ipython-command "ipython")))
`----

I hope this helps.

Dear Matplotlib help,

I have successfully created plots with quiver. The script is working.
However, I want to create multiple plots (quiver) with different datasets.
Due to the differences in datasets the length of the quiver is changing in
each plot. How can I keep the quiver length same in each plots? Note, I do
want variations in quiver length in the plot. I don't want the length of
each quiver equal in same plot.

I am using below in my script.
Q=ax.quiver(x, y, u, v, pivot-'tip')
qk = ax.quiverkey(Q, 0.78, 0.78, 5, '5 mph', labelpos='E',
coordinates=figure')

   1. scale function will not work.
   2. Normalizing the data will also not work

Please suggest/help.
RA

Why do you say this?  If I understand your question correctly, setting 
the scale and scale_units keyword arguments to the same value in each 
plot should do what you need.

e.g.

Q=ax.quiver(x, y, u, v, pivot-'tip', scale=10, scale_units='inches')

Bingo, it worked. I was using scale alone so it was not working. But worked
with scale_units.

Thank you Eric.

Sorry for the delay.  Life, work, etc. intervene.  I tried tk backend, failed but in a different way.  Seems to get ?farther? in that I can get a plot to render.

* Versions (all very recent from Anaconda): Python: 3.6.2  ipython: 6.1.0  matplotlib: 2.0.2

* My emacs startup has (elpy-use-ipython).

* With backend ?TkAgg?:

plt.ion()
figure(1)  --> window appears, with buttons on bottom (doesn?t happen with ?Qt5Agg? backend.  ipyton prompt works.  But, if I try interacting with the figure window, I get ?not responding? in title, and windows? spinning shell.  If I close the figure window by clicking on the X in upper right, windows says ?app not responding.?  Dialog box w/ End Process or Cancel.  End process kills figure and ipython session.

plt.ioff() instead:
figure(1)
plot(1,1)
show()
I get a figure window with a plot, but if I interact with it I get ?not responding.?  ipython prompt seems fine.  I can close window from prompt close(1) and ipython fine.

Help appreciated!  I hopefully won?t wait so long to respond.

Thanks,
Dave

That is at least all consistent!  The issue as that for what ever reason the input hook is not being set up correctly (which is what lets the GUI event loop spin and process events while the terminal waits for you to type).  With `plt.ion()` the terminal is blocking the process waiting for you to type (which is why the window is not responding), with `plt.ioff()` when you do `plt.show()` the GUI event loop is blocking the process (which is why it works, but you don't get the next prompt back until you close the plot window).  Again, see https://github.com/matplotlib/matplotlib/pull/4779 for a longer pass at explaining how this all works (and I would appreciate feed back about where it does not make sense!).

Try using `tkagg` as the backend, the integration between python and tk in a bit tighter (because it is done in the cpython source).

Which version of IPython and matplotlib are you using (and are you sure that elpy is using the versions you think it is?)?

are you using `(elpy-use-ipython)` or just hacking the python executable path?

You are siting at a very interesting intersection of technology here (emacs + python + GUI + windows).  It might make sense to ask either on the elpy mailing list or the ipython mailing list.

David,

Please subscribe to the mailing list so you can post un-moderated.

Which backend are you using?

If you get a window up and then do `fig.canvas.flush_events()` will it update?

If you do `plt.ioff()` and then `plt.show()` does it work?

I do exactly this as well (but on linux)!

The symptoms your are describing sounds like the GUI event loop is not being spun behind the scenes (see https://github.com/matplotlib/matplotlib/pull/4779 for some draft text at explaining how all of that works).  Have you tried doing `%matplotlib` is IPython?

Message-ID: <59A57869.3010807@wanadoo.fr>

Hello,
I use Win7 and the Anaconde suite of Python programs.
I am trying to write a piece of software to demonstrate the computation
of electric potentials. The software should ;

     - allow a user to select (with a mouse click) a point inside a 
blank rectangle,
     - record the x and y coordinates of  that point
     - draw a dot at that location
     - ask the user for the value of the charge located there and record 
that
     - repeat a few times
     - compute the electric potential and draw a contour plot of that 
function.

There are several pieces of code available showing how to print the x,y 
coor-
dinates of a mouse click but I can't devise a way to retrieve thes 
values for
turther computations nor can I dra a dot at the corresponding location
or insert a dialog to get the charge values.

I would be grateful for any suggestion.
JP Grivet
