Gi,

When I publish or send a Matplotlib script that uses 'gtk3agg' or 
'tkagg', can I just be sure that the recipients can use the backend my 
script does?

No, the available backends are determined by the packages installed by your
client.  That said, many (but not all) distributions of Python include the
tk bindings so if you want the highest probability of your users having the
backend of choice, go with tkagg.

That said, depending on what you are doing, you may be able to get away
with the GUI agnostic widgets.

Please see
https://matplotlib.org/tutorials/introductory/usage.html#what-is-a-backend for
more information on backends and
https://matplotlib.org/api/widgets_api.html?highlight=widgets#module-matplotlib.widgets
for
more information on the widgets.

Subject: [Matplotlib-users] Bug with changing formatter and locator of a
 secondary axis ?
Message-ID: <4bd502a1-b4be-284c-33d7-6d0700da3301@crans.org>

Hello,

I've a question on the secondary axis feature introduced in matplotlib
3.1
<https://matplotlib.org/3.1.1/users/whats_new.html#secondary-x-y-axis-support>.
I'm on version 3.1.1.


My use case is to plot log values but also display the exponentiated
values. I can use a twin axes with the shared scale and a functional
formatter. Here is an example:

    import numpy as np
    import matplotlib.pyplot as plt
    from matplotlib.ticker import LogLocator, FuncFormatter

    fig, ax = plt.subplots(1,1)

    # twin ax with shared scale
    # cf. @ImportanceOfBeingErnest at
    https://stackoverflow.com/questions/55907892/matplotlib-secondary-axis-with-values-mapped-from-primary-axis
    ax2 = ax.twiny()
    ax.get_shared_x_axes().join(ax, ax2)

    # Plot
    ax.plot([-1,2,5], [1,2,3], 'd-')

    ax.grid()

    # x axis labeling
    ax.set_xlabel('log2 x-value')
    ax2.xaxis.set_major_formatter(FuncFormatter(lambda x,pos:
    f"{2**x:.3g}"))
    ax2.set_xlabel('x-value');


This twinx/y approach works, but I wanted originally to use the new
secondary axis feature. I see to options for this:

 1. use a secondary axes with the log transform
 2. use a secondary axes with no transform, and then transform the
    display ticks using a FuncFormatter

Option 1 works initially, but breaks when I want to use a LogLocator to
have equally spaced log values:

    fig, ax = plt.subplots(1,1)

    ax.plot([-1,2,5], [1,2,3], 'd-')

    ax2 = ax.secondary_xaxis('top', functions=(lambda x: 2**x, np.log2))
    # Place ticks at log equally spaced location [doesn't work]
    ax2.xaxis.set_major_locator(LogLocator(2))

Option 2 doesn't work either due. Setting the formatter has no effect

    fig, ax = plt.subplots(1,1)

    ax.plot([-1,2,5], [1,2,3], 'd-')

    ax2 = ax.secondary_xaxis('top')
    # Format the log values as exponentiated values [doesn't work]
    ax2.xaxis.set_major_formatter(FuncFormatter(lambda x,pos:
    f"{2**x:.3g}"))


Is it an expected behavior (or a known bug) that changing the locator
and the formatter of a secondary axis has no effect? Did I miss something?

In the examples
(https://matplotlib.org/3.1.1/gallery/subplots_axes_and_figures/secondary_axis.html),
there is one example (number 3, with interpolated transforms)? which
uses secax.xaxis.set_minor_locator(AutoMinorLocator()), but I don't know
if it is effective or not.

Best,

Pierre

The fact that Opion 1 does not work is a bug. This has been fixed in the 
meantime, so it should work with the yet to be released matplotlib 3.2.

The fact that Opion 2 does not work can be considered a missing feature. 
Feel free to open an issue about it, which can be tagged as feature 
request/wishlist feature. 
(https://github.com/matplotlib/matplotlib/pull/14463 might be related.)

Hello,

I would like to contribute with the following examples for animations. 
Compared to some that I have found, they work with both dialogs and 
saving a file (without phantom artists). They do not redraw the whole 
canvas, but they do remove and recreate the original artist. I tested 
this on Parabola GNU/Linux 4.19.75-gnu-1-lts, Matplotlib 3.1.1, Python 
3.7.4, qt5ct (Qt version 5.13.1). I don't know if a license is required, 
but just it case, take GPL version 3.

Edgar,

Thanks for sending these along. Matplotlib falls under a BSD license, so
we'd need you to accept that before we could include them in the code base.

The best way to get these into the code base is by submitting a PR on
Github. We have a guide to contributing to matplotlib's development and
documentation here:
https://matplotlib.org/devdocs/devel/contributing.html

Cheers,
-Paul

Thanks, Edgar. Hopefully you find someone who will write the PR for you.

The matplotlib development team is well aware of the differences between
permissive licenses and copy-left licenses.

Hi Edgar,
Would you be opposed to sharing these on our discourse? We've got a forum
for showcase examples: https://discourse.matplotlib.org/c/showcase

Also, could we share these on social media? Particularly the Matplotlib
Instagram account? https://www.instagram.com/matplotart/

Thanks,
Hannah

FWIW, and speaking as a longstanding advocate of BSD, I think that the second part of this sentence:

> In my experience, the benefits of collaborating with the private sector are real, whereas the fear that some private company will ?steal? your product and sell it in a proprietary application leaving you with nothing is not.

has changed in recent years. Python is massive and in my field, for example, microscope manufacturers are bundling the Scientific Python ecosystem in their proprietary software that is then sold on for tens of thousands of dollars ? per year, because subscription software is the thing now.

imho, *at a minimum*, direct modifications to the software should always be contributed back. John Kirkham recently pointed me to the Mozilla Public License (MPL) that makes that requirement, while still allowing proprietary code to be distributed together with the open source component. I need to stew on this more, but I might start advocating for that instead.

Thanks, Paul. I assumed that. The quotes were meant for "the uninformed" 
:P . Thank you for Matplotlib in the name of countless students, 
reseearchers and many others.

Edgar,

I am glad you carefully read the ToC, however I am unwilling to consider
changing them without having a lawyer review the changes.

Message-ID: <FA650729-7426-49E8-9FBA-6D172F42D0DC@cfcl.com>

I'm hoping someone can tell me (point me to the ChanegLog for) when he axes kwarg was removed from matplotlib.pyplot.clabel, matplotlib.pyplot.contou, and matplotlib.pyplot.contourf. 

My search has turned up nothing.

I have code in an exercise for a class that called:

    plt.contourf(xx, yy, Z, cmap=ccolor, alpha=.2, axes=ax)
    cs2 = plt.contour(xx, yy, Z, cmap=ccolor, alpha=.6, axes=ax)
    plt.clabel(cs2, fmt = '%2.1f', colors = 'k', fontsize=14, axes=ax)

when run, this raised errors.

I've changed it to

    ax.contourf(xx, yy, Z, cmap=ccolor, alpha=.2)
    cs2 = ax.contour(xx, yy, Z, cmap=ccolor, alpha=.6)
    ax.clabel(cs2, fmt = '%2.1f', colors = 'k', fontsize=14)

and the errors are gone. However, a confirming reference would be helpful.

I don't think it ever was a keyword argument. Now, there have been some
bugs fixed recently where unused keyword arguments were going through
without emitting an error, which caused confusion when kwargs were
misspelled. Perhaps this is the change that is impacting you. To be clear,
I don't think it never would have done anything in the past.

I hope this helps!
Cheers!

not work. I would be grateful if you could assist me in this regard. Here
is my code:

import numpy as npimport matplotlib.pyplot as pltfrom scipy.optimize
import curve_fit

This is my model :

def concentration(T,a,b,c,d):
    (Tag,Tau)=T
    return np.exp(a-d/Tag)/(np.exp(a-d/Tag) +np.exp(b-c/Tau))

Here I use a variable T which is a combination of two independent variables
Tag and Tau. The output that I wish to fit is concentration.

T=[(7.9481e-04,5.9061e-04), (7.64438e-04,6.1231e-04),
(7.64438e-04,6.04905e-04), (7.85453e-04,6.01268e-04) ]
experimental_concentration = [0.5428,0.798,0.75,0.70]


many thanks,

Vicki,

https://github.com/matplotlib/matplotlib/pull/9111 is trying to _add_ the
ability to pass the axes into the pyplot methods via keyword.   From your
question, I infer that you would like this functionality to exist?

Tha would actually be useful. Many methods have it, others don't. Consistency is good and why have two methods when one will suffice?

Just to be clear, no methods have this right now. I am not sure why you
think "many methods have it". This is a design proposal. This will also not
eliminate any methods, contrary to your "why have two methods when one will
suffice". The ultimate goal of the design proposal (at least, how I view
it) is to begin to unify how plotting APIs look across packages.

My apologies. I'm VERY new to this and my wording was imprecise

Many _pandas methods_ have the ax argument.

>> why have two methods when one will suffice

Why force he user o go find another method when hey've already used one and only need to add one bit.

(beter wording? No?)

>> The ultimate goal of the design proposal (at least, how I view it) is to begin to unify how plotting APIs look across packages.

aka "consistency".

(you have an awesome name, btw. ;-)
