Question on PieChart slices

[neerajakshid]

Hi,

I would like to display a pie chart with two slices based on the users usage per month.

For example: if usage of the user is 0.92 (and monthly limit is 2)

then two slices have to be represented in the pie chart:

Slice 1: 0.92 in green color
Slice 2: 2 - 0.92 (monthly limit - users usage) in gray color

When I am using percentage for representing it.. It is not displaying correctly. Please help me how to achieve this. Thanks in advance.
