The following script, which started out life as the roudnup-reminder script, will generate a pie chart summary of the statuses in your tracker. It uses the PyChart library to do the actual charting. The script is:

 #! /usr/bin/env python
 import sys
 from pychart import *
 from roundup import instance

 # open the instance
 if len(sys.argv) != 2:
     print 'You need to specify an instance home dir'
 instance_home = sys.argv[1]
 instance = instance.open(instance_home)
 db = instance.open('admin')

 # analyse the tracker for the status summary
 data = []
 for sid in db.status.list():
     count = len(db.issue.find(status=sid))
     if count:
         data.append((db.status.get(sid, 'name'), count))

 # now call PyChart for the chart generation
 theme.output_file = 'out.png'
 theme.reinitialize()
 ar = area.T(size=(150,150), legend=legend.T(),
     x_grid_style=None, y_grid_style=None)
 plot = pie_plot.T(data=data, arc_offsets=[0,10,0,10],
     shadow=(2, -2, fill_style.gray50), label_offset=25, arrow_style=arrow.a3)
 ar.add_plot(plot)
 ar.draw()

the resulting "out.png" looks like:
