Pie chart data summarize

[Santiago Álvarez Martínez <salvarez igalia com>]

Hi all:

I'm using libgoffice to paint some data in a pie graph, but I have a
visual problem:

When some data have a few percentage of total value (i.e. 0.5%), it's
nearly impossible to see it. So I'd like to get every data with less
than a set value (i.e. 1%), to summarize them into an "Others" field.

Is this possible by setting some parameters?

Thank you in advance.

Santi Álvarez.
