Subject: [Matplotlib-users] Arc drawing
Message-ID: <CAG=b9FqfE=c0WNN3Y3mYo2H_ghTCTYh-L1ErtPR63wug5TCZ+w@mail.gmail.com>

Hello i have to draw an arc with matplotlib, i have the following data:

{'handle': '39D', 'owner': '1F', 'layer': 'AM_0', 'center': Vector(1000.0,
-1256.595067376733, 0.0), 'radius': 2100.0, 'start_angle':
67.75727639121727, 'end_angle': 112.2427236087827}
basically i have :
Center of the arc
Starting angle
end angle.
Do you have any suggestion

Regards

Hey Luca,

Matplotllib has an Arc artist:

Hey Luca,

You're referencing some variables in your snippet that you haven't defined,
so I can't really help you troubleshoot that.

Here's a basic example to get you started:

from matplotlib import pyplot
from matplotlib import patches

fig, ax = pyplot.subplots()

arc = patches.Arc(
    xy=(2, 3),
    width=5,
    height=5,
    angle=0,
    theta1=45,
    theta2=180,
)

ax.add_patch(arc)
ax.set_aspect('equal')
ax.autoscale()

4 things:
1. this is python3.9
2. it is mplcairo.  Selecting default backend save to pdf succeeds.
3. the message is coming  from pybind11.
4. occurs when saving to pdf and svg, but not png (others not tested)

Thanks for the quick response!

I didn't realize mplcairo was packaged for fedora and have been using the
local pip installed version.  The fixed version is not yet pip installable?

You need to install from master, e.g. `pip install git+
https://github.com/matplotlib/mplcairo`.  Otherwise you get the version
from PyPI, which is the last release (0.3.0), which was not marked as not
compatible with Py3.9 given that Py3.9 had not been released yet at that
point and that I therefore did not know it would require pybind11 2.6.0 and
would be compatible :-)

Thanks for the report.
I am aware of the issue and it has been fixed in mplcairo master (at
ddbc01c to be precise).  This arose because a backwards-incompatible change
in the latest pybind11 (2.6.0) broke mplcairo.  I am somewhat puzzled,
though, by how mplcairo managed to pass Fedora's CI (things broke locally
as well).
In any case mplcairo should be repackaged for Fedora 33 (attn. Elliott, I
guess :-) also, do you have an idea wrt. how mplcairo managed to pass the
tests on Fedora's CI?) using the current HEAD (or backporting just the
relevant commit, although that may not apply cleanly...) to support Py39.
(I may tag a new release too but no guarantees on the date for that.)

Subject: [Matplotlib-users] Title overwriting axis label
Message-ID: <CAG3t+pF2bRreL0U+iUEQQcNp4OjYUg_6rPUQ7ApUMJp1x2owCA@mail.gmail.com>

The plot is produced by the following code:

    import matplotlib.pyplot as plt
    ax = plt.gca()
    ax.ticklabel_format(style='sci', scilimits=(-3,3), axis='y')
    ax.ticklabel_format(style='sci', scilimits=(-3,3), axis='x')
    plt.plot (np.arange (start=0, stop=len(freq)*opt.segment,
step=opt.segment), freq)
    plt.xlabel ('time(symbols)')
    plt.title (r'$E_s/N_0=%s, \alpha=%s, \omega_n=%s, \Delta_f=%s$
mod=%s'%(opt.esnodB, opt.alpha, latex_float(opt.omega_n), opt.freq,
opt.mod))

    plt.ylabel ('freq(cycle/sym)')
    plt.tight_layout()

Any suggestions how to prevent this overlap of the title and the axis label?
This is mpl-3.3.3

Subject: [Matplotlib-users] Finalizing Code of Conduct
Message-ID: <CAOuQ7j09GVo3GSoC=3BTVxV8j7LHBfd57MQvqjJsi6EVoxGLOw@mail.gmail.com>

Hello community,
We have been revising our code of conduct and settled on using the latest
form of the contributor covenant with some minor customization for
reporting:
https://github.com/matplotlib/matplotlib/pull/18802

We chose this code of conduct based on these criteria:
1) lists the behaviors we think are appropriate and inappropriate
2) includes reporting and enforcement mechanisms
3) clear and concise

We are seeking holistic feedback on whether this new CoC is an accurate
statement of the behavior we expect in Matplotlib, our expectations are in
line with yours, and if there are significant issues with the text, Please
refrain from wordsmithing; we think that most problems are likely an issue
with the philosophy of the CoC and not solvable via changing some words
(plus or minus the reporting and enforcement sections).

We will be taking feedback for the next week (deadline Tuesday Nov 24th,
3:00PM EST) on the mailing list, discourse, pull request, and in private as
appropriate.

Thank you,
Hannah

Subject: [Matplotlib-users] Set text.latex.preamble in style sheet
Message-ID: <08525efa-55fc-fccf-97e1-0ec8833b951c@imperial.ac.uk>

Dear matplotlib developers,

Suppose I define a style sheet 'foo.mplstyle' as

text.usetex : True
font.family? : serif

and setting the LaTeX preamble in the following MWE:

import numpy as np
import matplotlib.pyplot as plt

plt.rcParams["text.latex.preamble"] = r"\usepackage{newpxtext} 
\usepackage{eulervm}"

plt.style.use('foo')

x = np.linspace(0.0,1.0,50)
y = x

plt.plot(x,y)
plt.show()

This works fine with matplotlib 3.3.0.

But the MWE fails when I try to set the LaTeX preamble directly in the 
style sheet. What's the correct syntax for 'text.latex.preamble'? I tried

text.latex.preamble : r"\usepackage{newpxtext} \usepackage{eulervm}"

text.latex.preamble : "\usepackage{newpxtext}, \usepackage{eulervm}"

text.latex.preamble : \usepackage{newpxtext},\usepackage{eulervm}

without success, despite seeing the API change notice 
<https://matplotlib.org/3.3.3/api/prev_api_changes/api_changes_3.3.0.html> 
about the parameter.

System info:

Ubuntu 20.10 Linux 5.8.0-29-generic x86_64
matplotlib 3.3.0 installed with apt
ghostscript 9.52
texlive 2020

Thanks for the support,

Thibaut

The API change is about setting the variable at runtime, not in a 
configuration file. The correct format for those is:

text.latex.preamble : \usepackage{newpxtext}\usepackage{eulervm}

The difference with your solution is the absence of comma (those are 
allowed for separating options of packages only).

For instance, mine:

text.latex.preamble: 
\usepackage{mathtools}\usepackage{xfrac}\usepackage{siunitx}\usepackage[lining,proportional]{ebgaramond}\usepackage{ebgaramond-maths}

Regards,
Bruno

Message-ID: <BF2D4032-0279-4B6C-B53C-77C0DB4BD269@netcourrier.com>

hi
i am creating a matplotlib draw (musical sales on a guitar) in function of some parameters (tonic note, type of gamme or chord...)
i am now creating tk radio buttons so that the user can choose the parameters
i can get these parameters and create the matplotlib picture with them
but the matplotlib will open a different window
would it be possible to have a same window, divided as a table, with at the lift the radio buttons, and at the right the matplotlib result ?
