Hi,
I am new to matplotlib.
I am trying to save a sample graph I created as a jpeg image. It seems form
the documentation that the type of image can be determined by the extension
that is used. Commands seem simple enough.
ind = arange(len(importance_IncNodePurity)) # the x locations for the groups
width = 0.35 # the width of the bars
p1 = bar(ind, importance_IncNodePurity, width, color='r')
ylabel('Importance')
title('Importance Node Purity')
xticks(ind+width, importance_row_names)
psave="c:\eclipse\dafaf.jpg"
savefig(psave)
show()
However, I seem to get the following errors and I have no idea what they mean.
Traceback (most recent call last):
File "C:\Documents and
Settings\dmontgomery\workspace\Test\src\create_table.py", line 259, in <module>
savefig(psave)
File "C:\Python25\Lib\site-packages\matplotlib\pylab.py", line 796, in savefig

raise IOError('Do not know know to handle extension *%s' % ext)
IOError: Do not know know to handle extension *.jpg
Thanks,
