Hi,

I am trying to generate a pie of pie chart and can't understand the logic behind how data is used. What I want to do quite simple:

a 25
b 159
b1 143
b2 16

I want to put and b in the big pie. the smaller pie should refer to b and has pieces b1 and b2.

If you have some idea how to do it, please let me know...

Thanks!

So I figured it in case someone gets stuck too. It should be entered like this:

a 25

b1 143
b2 16

with an empty row between the pies you want to separate.

If only this stuff occurs to you sooner than...
