[reportlab-users] Pass legend labels into LinePlot

Any help here? More details:
I'm modeling my code after one of the LinePlot examples. In that example,
in the __init__ method, the code does something similar to this:
sNames = ['Fund1','Fund2','Fund3','Fund4']
colorsList = [ lightgrey, grey, darkgrey, lightblue ]
for i in range(len(sNames)):
self.legend.colorNamePairs.append( (colorsList[i], sNames[i]))
And this works great, the chart renders with a Legend for those four Funds,
appropriately color coded. BUT, this isn't useful to me, I need to pass in
the labels dynamically, the same way I do the line data in the 'chart.data'
param. I can't find a parameter to use that would support this, and the
param data isn't available during the __init__ method anyway (not sure when
that gets set, or how to access it).
