Re: [Matplotlib-users] Certain annotation parameters cause strange error
I believe I fixed this in this pull request. https://github.com/matplotlib/matplotlib/pull/566 Unfortunately, I don't think there is a easy workaround other than not using the fancy arrow style. Regards, -JJ On Sun, Oct 30, 2011 at 1:51 PM, Brendan Barnwell brenb...@brenbarn.net wrote: I encountered a strange error when trying to put some annotations on a graph. I was able to simplify it to this: pyplot.plot([1, 2, 3, 4], [0, -1, -2, 8]) pyplot.annotate(Blah, xy=(2, 2), xytext=(-20,-20), textcoords='offset points', bbox=dict(boxstyle='round,pad=0.5'), arrowprops=dict(arrowstyle='fancy', connectionstyle='arc3,rad=0')) On my system (matplotlib 1.1.0 with Python 2.6 on Windows XP), this causes a long traceback culminating in File C:\Program Files\Python\lib\site-packages\matplotlib\bezier.py, line 129, in find_bezier_t_intersecting_with_closedpath raise ValueError(the segment does not seemed to intersect with the path) Increasing the xytext coordinates (in absolute value), to for instance (-50, -50) works with no error, and it also works without the special bbox style. Just guessing from the error message, it looks like certain combinations of fancy patches are causing problems because the shapes don't intersect in the way the drawing code assumes they should. I don't see anything in the docs about such edge cases, so this looks like a bug. Judging from the way that small tweaks to the code can cause the error to disappear, I imagine it could be tricky to fix, but at the least there should probably be a warning in the docs that some kinds of anootation boxes won't work with some kinds of arrows when the text is too close to the annotated point.

[Matplotlib-users] Animation module
Hello, I discovered the (wonderful) animation module in the v1.1 release today. However I think I may have quickly outgrown it a bit! I am plotting some simulation data see: http://dl.dropbox.com/u/2796140/mhdmodes_3.mp4 for an example made with the animation class. There is one thing missing from the above, which is colour bars! I have created the animation using the ArtisitAnimation class because each frame takes about 1-2 seconds to calculate the magnetic field lines, so using FuncAnimate would result in a very slow animation. The problem is that I can not add a colorbar instance to the list of artists that the animator draws as it is not an artist instance. This is a slightly modified version of the example [ http://matplotlib.sourceforge.net/examples/animation/dynamic_image2.html] that shows my problem: #!/usr/bin/env python An animated image import numpy as np import matplotlib.pyplot as plt import matplotlib.animation as animation fig = plt.figure() def f(x, y): return np.sin(x) + np.cos(y) x = np.linspace(0, 2 * np.pi, 120) y = np.linspace(0, 2 * np.pi, 100).reshape(-1, 1) # ims is a list of lists, each row is a list of artists to draw in the # current frame; here we are just animating one artist, the image, in # each frame ims = [] for i in range(60): x += np.pi / 15. y += np.pi / 20. im = plt.imshow(f(x, y)) cb = plt.colorbar() ims.append([im, cb]) ani = animation.ArtistAnimation(fig, ims, interval=50, blit=True, repeat_delay=1000) plt.show() Which generates the following error Traceback (most recent call last): File /home/stuart/Documents/VAC/sac_anim_axtest.py, line 28, in module repeat_delay=1000) File /usr/lib64/python2.7/site-packages/matplotlib/animation.py, line 356, in __init__ TimedAnimation.__init__(self, fig, *args, **kwargs) File /usr/lib64/python2.7/site-packages/matplotlib/animation.py, line 304, in __init__ Animation.__init__(self, fig, event_source=event_source, *args, **kwargs) File /usr/lib64/python2.7/site-packages/matplotlib/animation.py, line 53, in __init__ self._init_draw() File /usr/lib64/python2.7/site-packages/matplotlib/animation.py, line 363, in _init_draw artist.set_visible(False) AttributeError: Colorbar instance has no attribute 'set_visible' I attempted to add the colorbar to a AxesSubplot instance and then draw the axes in the artist list, however when I add a Axes instance to the artist list I get a wonderful error: Traceback (most recent call last): File /usr/lib64/python2.7/site-packages/matplotlib/backends/backend_gtk.py, line 122, in _on_timer TimerBase._on_timer(self) File /usr/lib64/python2.7/site-packages/matplotlib/backend_bases.py, line 1092, in _on_timer ret = func(*args, **kwargs) File /usr/lib64/python2.7/site-packages/matplotlib/animation.py, line 315, in _step still_going = Animation._step(self, *args) File /usr/lib64/python2.7/site-packages/matplotlib/animation.py, line 177, in _step self._draw_next_frame(framedata, self._blit) File /usr/lib64/python2.7/site-packages/matplotlib/animation.py, line 197, in _draw_next_frame self._post_draw(framedata, blit) File /usr/lib64/python2.7/site-packages/matplotlib/animation.py, line 220, in _post_draw self._blit_draw(self._drawn_artists, self._blit_cache) File /usr/lib64/python2.7/site-packages/matplotlib/animation.py, line 235, in _blit_draw a.axes.draw_artist(a) File /usr/lib64/python2.7/site-packages/matplotlib/axes.py, line 1994, in draw_artist assert self._cachedRenderer is not None AssertionError I also saw the subplots animation example [ http://matplotlib.sourceforge.net/examples/animation/subplots.html], however that is also based on FuncAnimate, would there be a way to create something similar for ArtistAnimate?

Thanks Stuart Do you need the colorbar scale to change with each frame? If not, you can create a wholly independent colorbar like so: cb = mpl.colorbar.ColorbarBase(cax, cmap=cmap, norm=norm) where 'cax' I usually get by using the axes_grid1 toolkit to pre-allocate a spot for a colorbar axes (as opposed to using fig.add_subplots()). However, if you need to the colorbar to change with the frames, then I would use the FuncAnimator, but a little differently than you are probably imagining. The fig.colorbar() function requires a ScalarMappable object (such as an object from imshow()). What I would do is prime the pump by creating the first frame. Then create a func animator that calls a function that loads the cached results based on an index number and directly update the imshow()'s object using the set_data() method. That way, the original colorbar sees the changes from the ScalarMappable object that was originally assigned to it. It also results in faster rendering, in my experience since

Re: [Matplotlib-users] Ternary Plot
The link on Nabble is broken, so here's (I think) a fixed version. It looks like the name of the branch was changed slightly at some point. https://github.com/kdavies4/matplotlib/compare/master...ternary2 Cheers, -Joe On Thu, Nov 3, 2011 at 3:14 PM, Benjamin Root ben.r...@ou.edu wrote: On Thu, Nov 3, 2011 at 2:58 PM, elmar werling el...@net4werling.dewrote: Hi, could not found anything like plot_ternary() in the matplotlib documentation.

[Matplotlib-users] use shapefile to create a mask?
Hi All, Is there a way to select only the values within a particular shapefile to analyse. I would like to do something like: array=numpyarraycoveringtemperatureofwholestate shapefile=forestedregions.shp newarray=ma.masked_values(array, shapefile) meantemperatureofforestedregions=MA.mean(newarray) print meantemperatureofforestedregions Any ideas of functions I could use, examples I could follow? thanks -- RSA(R) Conference 2012 Save $700 by Nov 18 Register now http://p.sf.net/sfu/rsa-sfdev2dev1___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
Re: [Matplotlib-users] use shapefile to create a mask?
To the best of my knowledge, this beyond the scope of matplotlib. Scipy or Shapely *might* have something for you, but you best bet is to look into the raster clipping functionality of GDAL/OGR.

Re: [Matplotlib-users] use shapefile to create a mask?
I've used Pyshapelib and Polygon to do this type of analysis in the past. Thuban may get ya what you need.
