Subject: [Matplotlib-devel] Gsoc Matplotlib Project on Categorical Axes
Message-ID: <8f24fb589e202c062f8e7b58709ff7a1.squirrel@webmail2.iitk.ac.in>

Hi I am Pratik, an undergraduate at IIT Kanpur in India. I would really
like to work on the matplotlib project on Categorical Axes that is
mentioned on the ideas page for NumFocus and Matplotlib. I have been using
matplotlib for my project and coursework for the last few months and i
understand the problem. However, since i am relatively new to open source
development, i would really appreciate it if someone could drop some
pointers to possible next steps for me.
Thank you.

Thanks, Pratik, and welcome.

The best thing you can do is just jump in and find a small task that you
could submit a pull request for.  This could be either a simple issue we
already have, or something that interests you (and doesn't have to be
related to your GSoC project).  We have a guide for using git with
matplotlib [here](http://matplotlib.org/devel/gitwash/index.html) and other
developer information [here](http://matplotlib.org/devel/index.html).

We look forward to seeing you on Github!

Cheers,
Mike

Hi,

I am Sandeep Bharti and I am currently in 3rd year pursuing my
undergraduate program in Computer Science. I am interested in the project
for making a user friendly API to deal with different types of data.
I have the required prerequisite for working on the project and I think I
will be able to work on it perfectly.

I want to discuss the idea and scope of the project so that I can start
researching on it as soon as possible and also it will clear all the doubts
regarding the project.
I will be very thankful if you can provide me the IRC for the project so
that I can contact the interested people to make it even better.

I will look forward to hear from you on this.

Many Thanks,
Sandeep Bharti

Message-ID: <CAH5rJVDrVR0-gcF=d9qJG7X7NQ3=p2BSw-1rFyO3_HESeyYPSA@mail.gmail.com>

Hi Developers,

I'm Yeshwanth from IIITDM Jabalpur, India. I want to develop a new API for
matplotlib which can automatically plot most of the visualizations required
by data scientists. For example plots like the one shown in this
stackoverflow issue (
http://stackoverflow.com/questions/14391959/heatmap-in-matplotlib-with-pcolor)
can be developed with a single function using the new API.

The API can deal with certain types of data as mentioned here
https://github.com/numfocus/gsoc/blob/master/2016/ideas-list-matplotlib.md#categorical-axes
.

Please let me know the things I've to consider before designing this API.

regards,
Yeshwanth

Yeshwanth,

Have you seen the seaborn package?
http://stanford.edu/~mwaskom/software/seaborn/

It builds off of matplotlib to make lots of nice statistical plots.

inspiration.

Hi Matt,

In response to "If something like wxmplot.PlotPanel and ImagePanel
(especially wrt giving end users a configuration panel to adjust the plot /
image) existed in PyQt, I would seriously consider switching many of my GUI
apps away from wxPython right now," have you ever looked at the PyQtGraph
module? http://www.pyqtgraph.org/ I'm guessing it loses some functionality
you would consider important and I'd be interested, if you have any
thoughts on it, to know where it falls down as in the past we have gone for
wx for building GUIs and the discussion about moving to Qt/PySide
continually resurfaces,

thanks,
Gary

Hello,

I am an undergrad Computer Science student at Amrita School of Engineering.
I am interested in working with pandas. I have 2 years of programming
experience in python and am familiar with the Git version control. I would
like to work on the Novice level bug fixes/enhancements project. Can anyone
guide me as to how I should proceed from here?

Thank you!

It's not quite what you want (no color cycling), but the style system we implemented knows how to apply itself to existing figures, axes, artists, etc.  It makes it pretty easy to modify drawing attributes after the figure is drawn and see the affects.  For example you can do this to modify a figure after it's on the screen:

smgr.set( fig, { "bgColor" : "black",
                 "fgColor" : "white",
                 "text.font.scale" : 1.25 } )

Ok, I was not expecting matplotlib to work this way. I was actually
thinking it was storing the drawing commands in some buffer, and was
actually doing the render when needed.

For my use case, I think I should better write a buffer on top of
matplotlib and only call it in the end, when I am actually drawing the
graph.

Thanks

Thanks for your interest.

This is the mailing list for matplotlib, so if you are interested in
working with pandas, you should contact those folks over on their mailing
list.

That said, we have some really fun project ideas ourselves here:
https://github.com/numfocus/gsoc/blob/master/2016/ideas-list-matplotlib.md
with instructions to get the application process for matplotlib gsoc

Hello,

I went through the project list and I'm interested to do the Documentation
Improvements projects as I feel it would suit my skill level and help me
learn more about how to automate tasks in python, which I'm very interested
in. How do I approach this project? And can I still apply even though I'm
not really an expert in python?

With versions up through 1.5.x, I don't think there is.  In 2.0 (not yet 
released) it is actually the default, but can be controlled using 
"axes.autolimit_mode" together with axes.xmargin and axes.ymargin. 
These margin parameters are available in 1.5.x, but autolimit_mode is not.

I would like to pull in the scope of this a bit (which was a bit unclear in
the initial posting).  The bulk of the work will not be in a 'charting'
API, but on making sure that the mpl internals will easily support such an
interface.  As others have pointed out there are already pointed out there
are several high-level packages that are built on top of mpl and we do not
want to pull the domain-specific aspects into core matplotlib.

For example, one thing we should support is to configure an `Axes` such that

fig, ax = plt.subplots()
ax.SOMEMETHOD(??)
ax.plot(['a', 'b', 'c'], [1, 2, 3])
ax.plot(['a', 'c'], [4, 5])
ax.bar(['a', 'b', 'c'], [.5, .75, 1])

'does the right thing' to first order.

Providing this functionality at the core will take a lot of burden off of
ex seaborn and pandas plotting.

Hi,

I am currently writing a test suite by which you input your matplotlibrc
file and it generates you a set of commonly used plots so you can examine
the aesthetics of your config.

I am having 2 issues,
1. How do I make SupTitle centered in matplotlibrc?
2. How do I make the points larger on the scatter plot?

See attached pictures.[image: Inline image 2][image: Inline image 1]

I'm happy to share the code if someone wants it.

I have.  I'm a happy user of a program that uses PyQtGraph. It seems
interesting, but very different from matplotlib (and so wxmplot).   I have
a similar view of VisPy.    I am happy with matplotlib.

For wxmplot I really wanted something to make interactive high quality 2D
line plots, including something like TeX support for text, and that also
does false-color image display (to allows relations between images and 2D
line plots).  Matplotlib is excellent for these needs.  PyQtGraph seems to
emphasize other things, including speed.  Though I often hear complaints
about matplotlib being slow,  I suspect this is due to confusion using
pylab.plot() with the plotting API.  I can easily update line plots at 15
to 25 Hz with wxmplot.  It's true that I do not use matplotlib for display
of video images -- I convert data from GigE and USB3 cameras directly to
wx.Images.  PyQtGraph seems good for that as well, but that is separate
from matplotlib.

I'm guessing it loses some functionality you would consider important and

Wxmplot provides a Plot-specific Panel with "plot" and "oplot" methods, as
well as live interaction for zooming, printing, copy-to-clipboard, and so
on.  Of course, most of this comes from the matplotlib API.   A
configuration form is readily available for end users to alter the plot
labels, colors, markers, etc for 2D line plots.  See
http://newville.github.io/wxmplot/plotpanel.html#examples-and-screenshots
for an example.  For false-color images, the user can change scales, color
tables, smoothing methods, and customize contour levels.   In a sense,
wxmplot improves on matplotlib default Navigation Toolbars, which are
pretty limited.

I've been using wxPython for more than 10 years and have no complaints with
its functionality, only that development for Python3 has been very slow
(and so I'm very grateful that Phoenix is now supported with matplotlib
1.5).  I don't see PyQt or PySide as actually being technically superior to
wx (except Python3 support), and find PyQt's use of the GPL annoying.  None
of wxPython, PyQt, or PySide seems to have a large enough group of active
developers, and I would worry about stability and support of the GUI
library no matter which of these I was using.

Again, I could be persuaded to try to migrate wxmplot to PyQt/PySide, but
would definitely base that on matplotlib.

Cheers,

--Matt

Hello!

My name is Rudolph Layko. I am pursuing my bachelor`s degree in Applied
Mathematics at National Research University - Higher School of Economics
(Moscow, Russia).

I would like to express my fascination by opportunity to contribute for
matplotlib due to the fact  that I am frequent user of this powerful
library. Especially, I am really interested in solving of issues that I am
personally was facing in process of using such as those concerning
categorical axes and losing a connection with original data while
plotting("Compound Artists"). Furthermore, It would be really great to
interact with professional team on opensource project.

According to this, I want to ask if there is anything that I can start to
working on right away in order to get more acquainted with problems, or
maybe you could provide me with some relevant information for the further
work.I have a strong background in main data analysis libraries such as
NumPy, Scipy, Pandas, SciKit. I hope this and some other technologies that
I worked with will help me to tackle the issues.

I am looking forward to hearing from you soon!

Best regards,
Rudolph Layko

It would be great if you wanted to submit an application.  The instructions
are here:

https://github.com/numfocus/gsoc/blob/master/CONTRIBUTING-students.md

To work on documentation, some basic knowledge of Python would still be
required, but not necessarily "expert level".

I recall conversations about using a lightweight version of traits to
manage configuration, etc for MPL.

Whatever became of that? Im interested because I could use  lightweight
traits-like sytem for another project -- wondering it it's been built
already.

my google-fu is totally failing me on this one.

We are planning to use traitlets which was developed and then spun out of
IPython.  We have a proof-of-concept branch from last summer.  Getting that
merged is one of the high priorities after 2.0 is out the door.

The "traits lite" library your looking for is called traitlets. It's well
worth checking out, if you haven't seen it yet.

There is no automatic way to center it over a column in an array of 
subplots, which appears to be what you want to do.  We don't have a 
layout engine, so there are many cases like this where positioning has 
to be done by figuring out the desired coordinates, perhaps based on 
querying other artists to find their bounding boxes, and then entering 
them in the function call.

> 2. How do I make the points larger on the scatter plot?

Use the "s" keyword argument to specify the desired area in points 
squared.  This will correspond to the size on the screen only if the 
figure dpi value is correct for your particular display.

re: centering: You may want to check the discussion there:
https://github.com/matplotlib/matplotlib/issues/5463
Briefly, adding a call to `fig.canvas.draw()` before creating the colorbar
can improve the situation a bit.

(sorry for the double posting, I had to delete the images).

Hello,

I have become increasingly frustrated with something that should really be simple in MPL: I want to be able to easily modify the colors of each word (or even letter) of a title (or text) in a plot (inside or outside of the axes).
On the MPL site, there is this:
http://matplotlib.org/1.5.0/examples/text_labels_and_annotations/rainbow_text.html
But there are 2 problems with this approach:

1.       It results in uneven spacing between words

and

2.       I cannot figure out how to apply a custom font style

Here is some sample code:
import matplotlib.pyplot as plt
plt.rcdefaults()
%matplotlib inline
from matplotlib import transforms

fig = plt.figure(figsize=(4,3), dpi=300)
hfont = {'fontname':'Nexa_Light.otf'}

def rainbow_text(x, y, strings, colors, ax=None, **kw):

    if ax is None:
        ax = plt.gca()
        t = ax.transData
        canvas = ax.figure.canvas

    #horizontal version
    for s, c in zip(strings, colors):
        text = ax.text(x, y,' '+s+' ', color=c, transform=t, **kw)
        text.draw(canvas.get_renderer())
        ex = text.get_window_extent()
        t = transforms.offset_copy(text._transform, x=ex.width-5, units='dots')
    print(ex)
plt.show()

rainbow_text(0.2,1.05,"This is a long sentence. I hope it works out well.".split(),
        ['b','r','g','orange','g','b','black','orange','g','b'],
        size=12,**hfont)
