Re: [Matplotlib-users] how to erase items in figures
The error was due to muppetdom of the highest degree... I've created a bash alias which subsituted ipython with ipython ---options. Subsequent use of ipython -pylab put the -pylab tab at the end and it was quietly ignored Sorry to waste people time Andy j vickroy wrote: Hello users, I wish to repeatedly re-plot labels and contour data on a figure since redrawing the figure is temporally expensive. The attached script (I apologize for its length), hopefully, illustrates a simplified version of what I'm trying to do -- contour temporally-varying data on a map projection. I do not understand how to erase the plot label each time the figure is to be reused. I also do not know how to erase the contour-fill although, based on the generated PNG files, it does not, for unknown reasons , appear to be necessary. From some postings, it seems that I have to employ collections attributes, but I have not been able to find documentation or examples that illustrate this.

Re: [Matplotlib-users] plotting a series of 3D points and, picker=True and 3D
The axes3d stuff is not currently working on the SVN trunk. You
probably want to use 0.91.2 or the v0_91_maint branch in SVN instead.
Cheers,

I think scatter3D does what you want:
from matplotlib import axes3d
import pylab as pl
fig = pl.figure()
ax = axes3d.Axes3D(fig)
ax.scatter3D(data[:,0],data[:,1],data[:,2])
ax.set_xlabel('X value')
ax.set_ylabel('Y value')
ax.set_zlabel('Z value')
pl.show()
You could also change the colour and size of each point based on other
array values:
col = ax.scatter3D(data[:,0], data[:,1], data[:,2], c=data[:,3],
cmap=pl.cm.jet, s=data[:,4])
cbar = fig.colorbar(col,shrink=0.9,extend='both')
cbar.ax.set_ylabel('axis 3 data values')
Pretty nifty.

[Matplotlib-users] Positioning annotations
Hi, I would like to annotate a bunch of points on a map. I'm trying to use the annotate function, but it need to know the text coordinates. So you have to configure manually in order not to have these annotations overlap each other. This is really annoying. Is there a way to : - detect the best position for theses annotation as with loc=best argument of the legend function ? - let me move theses annotations with the mouse ? I've heard that matplotlib gives the possibility of using events and signals. Can this be used in this situation ? Is there any example for this ?
