Re: [Matplotlib-users] [matplotlib-devel] matplotlib v1.4.3
Tom and other devs, Thanks for all the hard work! Looking forward to making the upgrade. Just curious if there is a detailed roadmap for v2 and beyond. I feel like there have been some rumors that the get/set architecture will be deprecated at some point.

[Matplotlib-users] Trouble getting colormap set_under and set_over to work with PolyCollection
I'm trying to control the over and under colors of a color bar with
set_under
and set_over on a ListedColormap object. I do not see the colors change,
but I
do see the arrows added to the color bar.
For example, the following code mostly works but the calls to set_under and
set_over seem to have no effect. I'm trying to use the color bar
documentation
at http://matplotlib.org/examples/api/colorbar_only.html as a guide. Maybe
I'm
doing something wrong or the example is slightly off?
I'm using matplotlib 1.4.0.
You can see examples of the images I'm generating here:
- https://github.com/matplotlib/matplotlib/issues/4117
It's been suggested to on the above tracker to use imshow. However, that
doesn't address the issue I'm having using PolyCollection. In addition, I'm
not sure how to translate my example below so that it will work with imshow
because I'm trying to plot a 2D slice of a 3D array.
The code in question is below. Sorry for not including re-usable array data
in
the example. My specific case is with a large 3D array that has several
thousands vertices, etc. Again, you can see the image examples here:
- https://github.com/matplotlib/matplotlib/issues/4117
import numpy
import matplotlib as mpl
import matplotlib.pyplot as plt
from matplotlib.collections import PolyCollection
vertices = numpy.load('vertices.npy')
array = numpy.load('array.npy')
# Take 2d slice out of 3D array
slice_ = array[:, :, 0:1].flatten(order='F')
fig, ax = plt.subplots()
poly = PolyCollection(vertices, array=slice_, edgecolors='black',
linewidth=.25)
cm = mpl.colors.ListedColormap([(1.0, 0.0, 0.0), (.2, .5, .2)])
cm.set_under('0.75')
cm.set_over('DarkViolet')
poly.set_cmap(cm)
bounds = [.1, .4, .6]
norm = mpl.colors.BoundaryNorm(bounds, cm.N)
bounds = [0.0] + bounds + [1.0]
fig.colorbar(poly, ax=ax, orientation='vertical', boundaries=bounds,
norm=norm, extend='both')
ax.add_collection(poly, autolim=True)
ax.autoscale_view()
plt.show()
Thanks,
Luke

I don't think this has anything to do with PolyCollection versus Image, and I was not suggesting that you use imshow. What I am suggesting is that you take my example and make the minimal changes required to convert it back to using your PolyCollection; or go the other way. I think the key point is the call to the colorbar method. Eric -- Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
