[reportlab-users] [patch] linecharts.py: allow labelFmt to be 'callable'

[Gael Chardon]

Hello,
hereafter a little fix for linecharts.py.
This patch replace the FunctionType test by  a 'callable' test like in 
barcharts.py. User can now set labelFmt to a class method and not only 
global function.

Regards.
