well for once Dinu has mis-remembered :)

you can actually use sequences as arguments to the bars thing.


eg

import reportlab
from reportlab.graphics.shapes import Drawing, _DrawingEditorMixin
from reportlab.lib.colors import blue
from fidelity.epscharts.webbuttons import yellow

class Drawing_003(_DrawingEditorMixin,Drawing):
        def __init__(self,width=400,height=200,*args,**kw):
                apply(Drawing.__init__,(self,width,height)+args,kw)
                self._add(self,reportlab.graphics.charts.barcharts.HorizontalBarChart(),name='chart',validate=None,desc=None)
                self.chart.bars[(0,1)].fillColor = yellow
                self.chart.bars[(0, 0)].fillColor = blue

if __name__=="__main__": #NORUNTESTS
        Drawing_003().save(formats=['pdf'],outDir='.',fnRoot=None)
