Question about gdchart module...

[Frederic Quin]

Hi all,


I know that the gdchart module was written in c (there is only a python
interface) but maybe someone knows more about it... I need to know how
is calculate the size of the grid and the size of a bar depending on the
size of the image and the number of bars. This is to create image maps
dynamicly. I can't really know how it is calculated.


Thanks
fred
