I have installed matplotlib (v. 1.0.1) which works with iPython quite good. But if I insert the same script in ArcGIS 10 or Eclipse 3.7.0 (with PyDev) I get always errors. As I consider to use matplotlib to create graphs with ArcGIS Python Scripts developed in Eclipse thats both pretty unfortunate - so far eclipse works quite well for ArcGIS 10.
F.i. I tested this one: http://matplotlib.sourceforge.net/examples/api/unicode_minus.html In iPython it works perfect.
In Eclipse I get this error: import matplotlib.pyplot as plt ImportError: No module named pyplot
And in ArcGIS I get this one: Running script Script1... : bad screen distance "640.0" Failed to execute (Script1).
Do I still have something to configure?
