You will very likely need to use the animation API for this. I
recently tried to demonstrate the Henon function in a fashion that it
appears I am drawing it over time:
https://www.youtube.com/watch?v=76ll818RlpQ
You can see the code linked from there:
https://github.com/amitsaha/playground/blob/master/recipes/henon_animation.py
That might give you a starting point of what you are trying to do.

Sorry, nothing much I can add here.
Best,

Hi,
I want to create an animation of the Lorenz attractor,
plotting each new point as it is generated by the
equations. So we see the graph "being drawn"
over time.
Also, as it is being drawn, I want to be able to
rotate the screen in 3 dimensions.
Will MatPlot do this on a Mac (10.8.5)?
Thanks!
PS -- here is code using MatPlot to create the "full" Lorenz:
http://matplotlib.org/examples/mplot3d/lorenz_attractor.html

My knee-jerk reaction is to move the definition of `format` outside of the
`Visualize.__init__` method. If you need to have hooks back into the
visualize method I would use a function factory + weak refs or a class
(again with weakrefs) with a `__call__` method.

Hey,
probably there is nothing to help me here, but I have a QtGui, using
matplotlib and basically end up in a circular reference hell that is not
resolvable by the gc. After removing almost all circular references, the
python inherited QWidget that embeds the figurecanvas is now deleted
fine.
The thing I end up with however is something like
class Visualize(object):
 def __init__(self):
 self.figure = Figure()
 canvas = FigureCanvas(self.figure)
 PythonInheritedQtWidget(self).element.setWidget(canvas)
 
 def format(*args):
 # do stuff
 return something 
 self.axis = self.figure.add_subplot(1, 1, 1) 
 self.axis.format_coord = format
 # This was completely drawn with canvas and all
 # PythonInheritedQtWidget is deleted fine.
I have not been able to get a minimal test case. But I have it pinned
down that everything can get cleaned up after:
del Visualize.axes.format_coord
so the circular reference that makes it not collectable is only the
format_coord which is a method pointing to the class owning the figure
and the axis. I am about to just use a weak reference wrapper function
to break the circle but it seems silly.
Anyway, I do not expect that anyone can help, and I expect it is some Qt
stuff really, but this is seriously annoying me....

This package is indeeed pretty nice, and I will surely take a look into 
it, but the way styles are added does not seem quite practical or shareable.
In my opinion, having a style file for each paper makes things more 
flexible, although this package may get more control out of the box.
Also, not being built-in makes you install an other package, and I think 
some people either do not want to do it, nor know how to do it.
On an other topic, I started working on some of the features you wanted 
to integrate with your PR 
<https://github.com/matplotlib/matplotlib/pull/2702>. I guessed that 
when you talked about adding the |set_ticks_location| to the rcParams, 
you wanted to control whether the ticks are in or out of the axes box?
Finally, I added a |style| parameter to the rcParams. It lets you choose 
from your |matplotlibrc| which style you want to use. On top of that, I 
made it recursive, so that you can design a style directly from other 
styles.
The only thing I could not get to work was to have your style loading 
directly when importing matplotlib (when defining from your rc file). 
You actually have to import the |matplotlib.style| lib to get your rc 
defined style to load up.
I will continue working on the other features described in olga’s PR 
<https://github.com/matplotlib/matplotlib/pull/2702> before submitting 
one on my own. But if you want to take a look, and tell me how I can 
improve what I did, you can find it on my repo 
<https://github.com/Mrngilles/matplotlib>.

There's also the "plotsettings" package which makes it easy to switch
between styles required by different papers.

Hi,
I guess I don't understand the "[axx for axx in ax.flat]" command, but this steals from all the axes.
Cheers, Jody
fig,ax = plt.subplots(2,2)
for i in range(2):
 for j in range(2):
 im=ax[i,j].imshow(np.ones((20,20)))
 im.set_clim([-1.,2.])
cax,kw = mpl.colorbar.make_axes([axx for axx in ax.flat],shrink=0.5)
plt.colorbar(im, cax=cax, **kw)

An old example of something like this is here:

Hi,
One final reminder that I am a mentor for two Google Summer of Code
projects that involve extensive matplotlib GUI development for python
scientific software.
The INCF (incf.org) is sponsoring two GSOC projects that will directly
benefit PyDSTool (http://pydstool.sf.net), a math modeling toolbox for
science and engineering that some of you will know. One, if not both,
of the projects will involve significant technical usage of MPL's 2D
GUI widgets but, more excitingly, to build new types of model
visualization tools over MPL. MPL has been chosen to maximize platform
independence and minimize reliance on additional user installation of
third party libraries, and is well suited for the prototyping of
application front ends for research code.
http://incf.org/gsoc/2015/proposals/#-span--span----nbsp---span---span--span-neuroscience-model-exploration-and-development-tools-for-pydstool--span-
High level knowledge of math and the theoretical principles of cell
biology are beneficial but not required.
Applications can begin right away! Read more about the process here:
http://www.google-melange.com/gsoc/homepage/google/gsoc2015
Thanks,
Rob

Hi,
.
Your example is not much clear. It's better post some short example and a
running piece of code.
btw, maybe your problem should be solved with this post:

Hello all,
I make multi plot with colorbars. I need help, how do make only one
colorbar for six panels? I also want to show only lowest x-axis. I copy my
recent code and figure here.
 # Open file
 fd = nc.Dataset(fname, 'r')
 # Read variables
 beam = fd.variables['beam'][:]
 rng = fd.variables['range'][:]
 tim = fd.variables['time'][:]
 pwr = fd.variables['pwr'][:]
 nfft = fd.variables['nfft'][0]
 pn = fd.variables['pnoise'][:]
 width=fd.variables['width'][:]
 # Close netCDF file
 fd.close()
 # Specify beam
 ibeam = ibeams[i]
 # Time convertion
 tim = tim/3600.0
 #Plot
 p_plot = pwr[ibeam]
 for it in range(len(tim)):
 p_plot[it] = p_plot[it] - pn[ibeam][it] - 10.*np.log10(nfft)
 p_plot = p_plot.transpose()
#Specify subplot
 pl.subplot(611 + i)
#Contour plot
 v= np.linspace(5., 50., 5., endpoint=True)
 x= pl.contourf(tim, rng, p_plot, v, cmap=pl.cm.jet)
 x = pl.colorbar(ticks=v)
 x.ax.set_title('dB')
 print x
# Set X and Y axis lower/uppser limit
 set_xy = range(4)
 set_xy[0] = 18.0 # x min
 set_xy[1] = 30.0 # x max
 set_xy[2] = 200.0 # y min
 set_xy[3] = 550.0 # y max
 pl.axis(set_xy)
# Set labels
 pl.xlabel('time (hours)')
 pl.ylabel('range (km)')
 pl.show()
Thank you....

Ahh! Yes that is likely it. I assumed that relative dimensions were always
with respect to the previous point, but they are always with respect to the
previous non-control point.
Thanks!

This is a bit hacky, but there is apparently no validation that 'width' is
positive. If you set the `width` kwarg to negative you effectively get to
set the right edge.

Marin,
The sort of capability you are describing here is not possible with the 
present architecture.
Eric

the rcparams are stored in a sub-class of dict which does both name and
value validation on the way in. This is controlled by the class-level
attribute `validate` (which is a dict mapping from key-name -> validation
function). In principle you could update this dict to add rcparams on the
fly, however if the plotting functions don't know to look at the rcparams
they won't have any effect. To add new rcparams you need to modify the
upstream code.
There is a PR to add spine-related rcparams (
https://github.com/matplotlib/matplotlib/pull/2702) but it has not been
active in a while.

Hello everyone,
After working a bit on the styles, I noticed that some parameters could 
not be modified using an rc or style file (for example, turning off the 
right, left, up or down axis). I kind of saw how to do it using the 
|Axis.spine.set_visible()| method, but it would be better to be able to 
change it in the rc.
So I was wondering if there would be a way to add rcParameters using a 
method with an external file, or if I would have to change this in the 
mpl source?
Maybe a method that would add rcParameters on demand...
Thanks

The bar plot options allow you to set align='center' or align='edge'
But when it aligns on the edge, it always does left align. 
I can't find any documentation that allows me to align it as a right
align. Is this possible?

Actually, both syntax are valid.
I think the problem in you svg parser is that you're changing the reference point each time you iterate in points.
For example consider the path:
m 100,200 c 100,100 400,100 400,200 z => (m P0 c P1 P2 P3 z)
Your parser ended with vertex at (100.0, -200.0), (200.0, -300.0), (600.0, -400.0), (1000.0, -600.0)
which corresponds to [P0, P0+P1, P1+P2, P2+P3] but you want [P0, P0+P1, P0+P2, P0+P3]

For some reason Inkscape outputs a single leading "c" for the bezier curve in my path whereas your path has a "c" for every three points. I'm not quite sure the difference, maybe Inkscape outputs a non-standard form.

Nertskull,
If no one responds, you might repost with some examples of what you’ve tried. I would suggest xticks and company, but I’m not sure if it works in your situation.

I've searched and can't figure this out.
And I'm not sure exactly the best way to do it.
Basically, I'm trying to make a bar graph, and I have about 400 bars (so
400 x-axis 'groups').
When I plot it, I get every bar labelled, but that is too much to be
seen. How do I make it so I only label every 10th bar, or every 50th bar?
The data is ordered data, so it doesn't matter if many don't have a label.
Thanks.

I indeed planned on making examples for every available style. Tony Yu's 
style gallery seems indeed quite interesting, I'll take a look.
I also planned to register it into USER_LIBRARY_PATHS to import it 
directly. You shouldn't have to import an other plugin if you wish to 
use a matplotlib built-in style...
You also talked about migrating to the main mpl organization. How 
exactly would that work?
Thanks
Marin

Actually the notation I have is valid SVG path data. Your script could be
modified to handle the more general forms, see:
http://www.w3.org/TR/SVG/paths.html#PathDataGeneralInformation
But this still doesn't answer why the smoothness is different between the
SVG and matploblib paths. I haven't been able to figure that out yet.

That repo should probably be folded together with Tony Yu's style gallery
code and eventually be migrated to live under the main matplotlib
organization.
I would also advocate for adding a bit of code into that repo to make it
importable and to register all/some of it's style files with the
USER_LIBRARY_PATHS attribute in mpl.style.core so that these things 'just
work' by name if you import `mpl_styles` (ex `style.use('journals.pre')`
would enable the styles for Physical Review E).

Thanks Nicolas for your code.
The difference in what I have and what you share is in the svg path
specification. For some reason Inkscape outputs a single leading "c" for
the bezier curve in my path whereas your path has a "c" for every three
points. I'm not quite sure the difference, maybe Inkscape outputs a
non-standard form.

That would indeed would be nice, and get us started.
I created a repository <https://github.com/mrngilles/matplotlib-styles>, 
if anyone wants to contribute. Don’t hesitate to bring in some new ideas.
