[reportlab-users] BarChart barLabelCallout ?

[Dirk Datzert]

Hi,

I found a new attribute in BarChart:

 barLabelCallOut = AttrMapValue(None, desc='Callout
function(label)\nlabel._callOutInfo
=                                                     
(self,g,rowNo,colNo,x,y,width,height,x00,y00,x0,y0)'),

Can anybody explain ?

Regards,
Dirk
