[reportlab-users] Height of individual bars

[Marcus Vinicius Laranjeira]

All,

I am writting a automatic report generator, and sometimes I have a chart 
with 5 or 6 bars, and sometimes the same chart could be generated with only 
2 or 3 bars, but both of them have (and must have) the same drawing width 
and height, and because of this, when a chart with 2 or 3 bars is created, 
the bars are too thick (this is a horizontal bar chart) and the space 
between them are to high !

Is there a way to change the height (thickness) of the bars, in case of 
having 2 or 3 bars !?

Thanks a lot !!!

Marcus
