matplotlib-devel Mailing List for matplotlib

I would keep an eye on scikit-image and their viewer work.  One of the
drivers behind Steven working on the nbagg backend was prep work to port
their imageviewer code over to using nbagg from than qt.

I think it is also possible to interact between ipython widgets and
figure/axes objects with nbagg.

I think you are correct.  John Hunter explicitly avoided the temptation 
to keep adding backend-independent widgets to mpl; we have a hard enough 
time trying to maintain and improve the plotting capabilities without 
trying to turn mpl into a wxwidgets work-alike.  If you need more than 
the very minimal widgets presently on offer, you have to choose a gui 
toolkit and use it directly, embedding matplotlib in it.

ginput works fine in a GUI window, but there is no matplotlib widget where I can type text or numbers in a box. Like the FloatTextWidget in IPython. Or am I missing something?

Hey all,

If anyone is interested, there is a software position open at BNL in the
group I work with:

https://www.bnl.gov/hr/careers/jobs/?cpUrl=https://careers.peopleclick.com/careerscp/Client_BrookhavenLab/external/en_US/gateway.do?functionName=viewFromLink&localeCode=en-us&jobPostId=525

Please forward this to anyone who might be interested.

Tom

I'm 99% sure you can do this in a GUI window. Does your solution have to be
in the notebook?

Thanks, Tom.

I want to use ginput to draw a straight line on a graph.
The line is used to select a cross-section of a contour plot.

I was afraid it wasn't going to be easy.

Getting to it from the other side, is there a matplotlib widget in the
works where I can type text or numbers in a box? Like the FloatTextWidget
in IPython?

Problem is I want to make a small GUI that includes both a text widget
(which is available in IPython) and a 'select points in graph' widget like
ginput in matplotlib.

nbagg is always running in the IPython event loop (as I understand it), so
I am not sure how to integrate that with the blocking.

On the 1.4.x/master branch we have support for (almost, one PR still
pending) all mouse and keyboard events so all of the mpl widgets should
work (big thanks to Steven Silvester).  T

What do you want to use that relies on ginput?

You can fake up a non-blocking version something like:

from collections import deque
```
class accumulator(object):
    def __init__(self, n=5):
        self.list_of_points = deque(maxlen=n)

    def on_event(self, event):
        self.list_of_points.append(event)

import matplotlib
import itertools
import numpy as np
matplotlib.use('nbagg')
import matplotlib.pyplot as plt
plt.close('all')
fig, ax = plt.subplots()
x = np.linspace(0,10,10000)
y = np.sin(x)
ln, = ax.plot(x,y)

dd = accumulator(15)
fig.canvas.mpl_connect('button_press_event', dd.on_event)
plt.show()
```

and then get the points by

```
dd.lest_of_points
```

This code obviously needs lots of bells and whistles, but points in the
right direction.

Hello List,

Are there any plans to make ginput work in the nbagg backend?

It would be so cool if I could use that in an IPython Notebook together
with the other widgets.

Thanks,

Mark

I’ve worked out how to create a Poly3DCollection as noted by Maximilian Albert and how to use the set_array method on the collection created by plot_trisurf as noted by Geoffroy Billotey. I have two follow up questions:


1)      Would it be possible to make it so that if the color parameter of plot_trisurf is an array of length n_triangles, that plot_trisurf would internally use set_array to color the triangles with the colors in the color parameter?

2)      Is there a way to color the triangles with gradients? I have an intensity value at each vertex of the triangles so Matlab/octave colors each triangle with a gradient whereas right now I’m taking an average of the values at the vertices and assigning the resulting value to the triangle.

Hi,

You can also try to pass a *color* array of size ntri (number of triangles) to the *set_array* method of the collection returned by *plot_trisurf*.

See for instance:

Hi Byron,

This is a bit of a workaround, but you can specify facecolors explicitly by creating a triangulation of your surface explicitly and creating a Poly3DCollection with these facecolors. I'm attaching an example below which is a modified version of the plot_trisurf demo [1] in the matplotlib documentation. It showcases both random colors and a smooth gradient (the latter in the line that's commented out).

I would have thought that it should be possible to pass an argument like "facecolors" to plot_trisurf directly, since the documentation [2] states that "other arguments are passed on to Poly3DCollection". However, I couldn't get this to work quickly. Maybe someone else knows how?

Best regards,
Max

Thanks. This looks like it might work for me. I got your example to work, but I still need to figure out how to apply it to my problem. In particular there is the note about your Triangulation line which says that we assume there is a nice projection of the surface into the x/y-plane. Is this just a requirement of the Triangulation function or of the Poly3Dcollection? My surfaces are typically enclosed bodies, but since they’re meshed for the Electromagnetic Simulation I already know the connectivity of the vertices. Also, in your example it appears that you define one color per triangle but the trisurf files I have consist of one color per vertex. Will I need to come up with my own function for defining facecolors based on the three color values associated with each of my triangles?

Hi Byron,

This is a bit of a workaround, but you can specify facecolors explicitly by creating a triangulation of your surface explicitly and creating a Poly3DCollection with these facecolors. I'm attaching an example below which is a modified version of the plot_trisurf demo [1] in the matplotlib documentation. It showcases both random colors and a smooth gradient (the latter in the line that's commented out).

I would have thought that it should be possible to pass an argument like "facecolors" to plot_trisurf directly, since the documentation [2] states that "other arguments are passed on to Poly3DCollection". However, I couldn't get this to work quickly. Maybe someone else knows how?

Best regards,
Max

Hi Byron,

This is a bit of a workaround, but you can specify facecolors explicitly by
creating a triangulation of your surface explicitly and creating a
Poly3DCollection with these facecolors. I'm attaching an example below
which is a modified version of the plot_trisurf demo [1] in the matplotlib
documentation. It showcases both random colors and a smooth gradient (the
latter in the line that's commented out).

I would have thought that it should be possible to pass an argument like
"facecolors" to plot_trisurf directly, since the documentation [2] states
that "other arguments are passed on to Poly3DCollection". However, I
couldn't get this to work quickly. Maybe someone else knows how?

I often have Electromagnetic surface current data which I use MATLAB's trisurf function to plot. Since the surfaces are 3-dimensional I need a trisurf plotting tool which lets me specify the color of each triangle/vertex. MATLAB's trisurf function allows me to do that by passing it an array of colors (http://www.mathworks.com/help/matlab/ref/trisurf.html) along with the arrays of X, Y, and Z coordinates of vertices. 

Matplotlib's plot_trisurf from mplot3d only seems to allow me to specify one constant color for the entire trisurf plot or to color the triangles according to the z-coordinates. Are there any plans to add this functionality to mplot3d's plot_trisurf? Does anyone here know how difficult it would be?

Byron Boulton

Tom,

Thanks for setting this up.

 Subject: [Matplotlib-users] Matplotlib and Numfocus Fiscal Sponsorship	Agreement (FSA)
 To: "mat...@li..." <mat...@li...>, "matplotlib-users" <mat...@li...>
 Date: Wednesday, January 21, 2015, 12:48 AM
 
 
   
 
     
   
   
     
     
       Matplotlib
           is a widely used, well regarded, and powerful
 visualization
           library that has dominated the Python
 visualization stack for
           over a decade. However, to maintain that position,
 matplotlib
           must continue to evolve. Complementary or
 alternative
           libraries are appearing at an increasing rate,
 including
           browser-based plotting and GPU acceleration. To
 maintain its
           leadership position for the next decade,
 Matplotlib must
           interface with these alternatives while
 simultaneously
           expanding its capabilities and becoming easier to
 use and
           learn.
       
 
       Matplotlib’s
           large existing user base (greater than 50,000)
 means that new
           developments need to be carefully balanced with
 maintaining
           existing interfaces.  With the large user and
 code base comes
           a significant maintenance and user-support burden.
  These
           responsibilities currently account for a majority
 of the
           core-developer time spent on matplotlib and has
 resulted in
           both the code base and community being in a
 healthier state
           than ever before. Even 6 years ago there was no
 automated
           testing to speak of and the number of contributors
 continues
           to soar on github. However, this effort is, for
 the most part,
           done on a volunteer basis in the nights and
 weekends of the
           core developers.  To go beyond this maintenance
 level—to make
           step-change improvements for the benefit of
 matplotlib’s
           users—will require funding for full-time
 developers. Inspired
           and encouraged by the example of IPython, we would
 like to
           begin the process of fundraising.
       
 
       Managing
           funding on the needed scale is a complex and
 time-consuming
           process.  Thankfully, NumFOCUS, a 501(c)3 charity
 organisation
           co-founded by John Hunter, offers a fiscal
 sponsorship
           agreement to minimize the administrative and legal
 burden on
           open source projects. We would like to enlist
 NumFOCUS as our
           agents in all legal and financial matters,
 including banking,
           accepting donations as a non-profit, payroll, and
 access to
           legal counsel.  As part of the agreement,
 NumFOCUS would
           charge a percentage of all funds raised to cover
 their costs.
            The full text of the agreement is
 attached.
       
 
       To
           comply with the legal and accounting requirements
 of a
           non-profit, matplotlib needs to form an
 administrative body to
           interact with NumFOCUS and direct the disbursement
 of any
           funds.  The proposed initial members of the body,
 are myself
           (Mike Droettboom), Eric Firing, Phil Elson, and
 Thomas
           Caswell, with Thomas acting as the point of
 contact with
           NumFOCUS.
       
 
       In
           practice, signing an FSA will have very little
 impact on the
           matplotlib project itself - it will still be
 BSD-licensed and
           community-driven as it has always been, and the
 only
           motivation for doing this is to give us an
 opportunity to
           apply for funding to do more work on matplotlib.
 We'd like to
           canvas the community's opinion on the matter,
 but to put a
           concrete timeline on the discussion, we would like
 to propose
           signing an FSA with NumFOCUS in 3 weeks (Feb 10th
 2015) unless
           there is a major community discomfort with us
 doing so. 
 
         
       
 
           Cheers,

The column asignments are tags + open/close status.

https://waffle.io/matplotlib/matplotlib/settings/columns _should_ drop you
to the webpage that lets you see how they are controlled (you might need to
log in to see it).  It has been set up for a while now and no one has
complained about GH breaking, so I think it is pretty side-effect less.

Looks good to me.  As far as I can see, it is not doing anything that 
would interfere with ordinary direct github use.

What determines the column assignments?  A combination of tags and 
open/closed status?  Is there something else going on?

I like it.  I could make some nitpicks, but I think it's clearly 
superior to raw github alone, and on that basis I have no objections.  I 
think we should make sure we don't make the experience using github 
alone any worse, though, as I'm sure for some the familiarity there from 
other projects will be most important.  It doesn't *seem* like it does, 
but I think it's important to consider.

Matplotlib is a widely used, well regarded, and powerful visualization 
library that has dominated the Python visualization stack for over a 
decade. However, to maintain that position, matplotlib must continue to 
evolve. Complementary or alternative libraries are appearing at an 
increasing rate, including browser-based plotting and GPU acceleration. 
To maintain its leadership position for the next decade, Matplotlib must 
interface with these alternatives while simultaneously expanding its 
capabilities and becoming easier to use and learn.


Matplotlib’s large existing user base (greater than 50,000) means that 
new developments need to be carefully balanced with maintaining existing 
interfaces.  With the large user and code base comes a significant 
maintenance and user-support burden.  These responsibilities currently 
account for a majority of the core-developer time spent on matplotlib 
and has resulted in both the code base and community being in a 
healthier state than ever before. Even 6 years ago there was no 
automated testing to speak of and the number of contributors continues 
to soar on github. However, this effort is, for the most part, done on a 
volunteer basis in the nights and weekends of the core developers.  To 
go beyond this maintenance level—to make step-change improvements for 
the benefit of matplotlib’s users—will require funding for full-time 
developers. Inspired and encouraged by the example of IPython, we would 
like to begin the process of fundraising.


Managing funding on the needed scale is a complex and time-consuming 
process.  Thankfully, NumFOCUS, a 501(c)3 charity organisation 
co-founded by John Hunter, offers a fiscal sponsorship agreement to 
minimize the administrative and legal burden on open source projects. We 
would like to enlist NumFOCUS as our agents in all legal and financial 
matters, including banking, accepting donations as a non-profit, 
payroll, and access to legal counsel.  As part of the agreement, 
NumFOCUS would charge a percentage of all funds raised to cover their 
costs.  The full text of the agreement is attached.


To comply with the legal and accounting requirements of a non-profit, 
matplotlib needs to form an administrative body to interact with 
NumFOCUS and direct the disbursement of any funds.  The proposed initial 
members of the body, are myself (Mike Droettboom), Eric Firing, Phil 
Elson, and Thomas Caswell, with Thomas acting as the point of contact 
with NumFOCUS.


In practice, signing an FSA will have very little impact on the 
matplotlib project itself - it will still be BSD-licensed and 
community-driven as it has always been, and the only motivation for 
doing this is to give us an opportunity to apply for funding to do more 
work on matplotlib. We'd like to canvas the community's opinion on the 
matter, but to put a concrete timeline on the discussion, we would like 
to propose signing an FSA with NumFOCUS in 3 weeks (Feb 10th 2015) 
unless there is a major community discomfort with us doing so.


Cheers,
Michael Droettboom

I wondered if someone could take a look at Issue #3918 (https://github.com/matplotlib/matplotlib/issues/3918).  As you can see in my last two posts, everything works fine if I have one bbox image or if I don't save as a pdf.  However, if I have two bbox images, the images move when I save as a pdf.  

This seems like a relatively small issue to fix, so I have tried to debug the problem, but I have been unable to find the source of the issue.  If anyone could point me toward where the problematic code is, I would be happy to fix it, test it, and submit the PR.
