[Matplotlib-users] matplotlib with eclipse: how to get a graph?
Hello list, I recently started using Eclipse with Pydev. I like it a lot but have not been able to get interactive plotting going (which otherwise works fine). My file is simple: from pylab import * ion() plot([1,2,3]) When I run this form within Eclipse, I do see a graphing window open up but then it disappears again when it is done, before I can even look at it. Any suggestions on how to keep the graphing window open? Thanks, Mark -- Come build with us!

Does Pydev have any sort of specific support for matplotlib? I'm asking because even in the normal Python shell interactive work can be difficult, depending on the backend, and whatever command-loop magic IPython does makes it work better. You could try different backends, but I suspect that Pydev would have to have specific support for integrating the backend-specific command loop for it to really work. -- Jouni K.

[Matplotlib-users] colorbar tick label fontproperties
Could someone please explain how to change the font properties for a colorbar
tick label, the following causes no error, but it does NOT work:
## CREATE COLORBAR
## make a copy of the image object
im2 = copy.copy(im)
im2.set_cmap(colmap)
## create new axis for colorbar.
cax = plt.axes([l+w+0.03, b, 0.025, h-0.035])
cb = plt.colorbar(im2, cax)#, format='%3.2g') # draw colorbar
## set colorbar label and ticks
p_cax = mpl.font_manager.FontProperties(size='6')
clabels = clevs[::10] ##clevs, by 10 steps
clabels.append(clevs[-1]) ## add the last label
cb.ax.set_yticks(np.linspace(0,1,len(clabels)))
cb.ax.set_yticklabels(['%3.2g' % cl for cl in clabels],
fontproperties=p_cax)
cax.set_title('sensitivity\n(%s)' % units,
fontproperties=p_cax)
NOTE: It does set the title properties correctly.

[Matplotlib-users] circle collection get_facecolors in Basemap
Hello, I'm trying to plot text objects with the color used in m.scatter. My goal is to individually label each scatter object. I've tried the following: circles=m.scatter(cx,cy,zsize,zlevel,cmap=cmap) and then: CC = circles.get_facecolor() i=0 for x,y in map(cx,cy): ax.text(x,y,'some text', color=CC[i]) But if fails because: m.scatter returns: matplotlib.collections.CircleCollection object at 0x127898d0 Rather than a list of objects??? Or something. The point is, I would expect 'circles' above to have len==cx, but it does not.

Re: [Matplotlib-users] colorbar tick label fontproperties
John,
The following code works for me (Python 2.5.4, Matplotlib 0.99):
# create and format the colorbar
cbar = pl.colorbar(G, ticks=range(g1,g2+1))
cbar.ax.set_ylabel('Gradient (%)', fontsize=10)
cl = pl.getp(cbar.ax, 'ymajorticklabels')
pl.setp(cl, fontsize=10)

The first thing you are doing wrong is failing to provide a complete, minimal, self-contained example illustrating the problem. I don't think the snippet you gave is representative of what you are running. Instead of map I think you mean zip. Where are you incrementing i? The general approach of using the get_facecolor() method to get the array, and indexing into it, is fine. That is not where the problem is. Once you put together a minimal example, I think you will find the problem--or that there really is no problem. A collection is used by scatter because it is much more efficient than a sequence of objects. Eric -- Come build with us!
