Hi, I'm hoping you can help. I've been reading through the matplotlib
documentation but finding it fairly confusing.
I am plotting some pie and bar charts, example code would be similar to,
def makepie(labels,slices,titlestring,outputname,FIGUREID,FIGSIZE):
colorrange=[]
for c in range(0,len(labels)):
colorrange.append(( 0.5 ,0.5,0.5+(c*(0.5/len(labels)))))
figure=plt.figure(FIGUREID, figsize=FIGSIZE)
axes=figure.add_axes([0.1,0.1,0.8,0.8])
chart=plt.pie(slices,labels=labels, shadow=True, colors=colorrange)
#update formatting
for pieslice in chart[1]: #0 is patches, 1 is text instances
pieslice.set_fontname('Arial')
pieslice.set_fontsize(6)
figure.get_axes()[0].set_title(titlestring, bbox={'facecolor':'0.75',
'pad':6}, fontsize='x-small')
plt.savefig(outputname)
The trouble is, the resulting pie isn't so pretty, and example is
http://www.nabble.com/file/p26060403/client_by_migtime.png
I would like some general examples for updating the formatting - for example
no matter what I have tried so far I cannot get the background to be
transparent rather than white, I dont really understand how to adjust the
positions of the labels and what options I have with the pie chart for doing
that.
I did figure out the font size and type changes, but that was more a shot in
the dark - I dont really understand the object I have programmatically or
the 'model' behind matplotlib and how it constructs an image.
I understand this is a slightly vague question, but hope someone can help!
Thanks,
Matt.
