Hi all,

I have encoutered a problem with position of labels only
when data have some specific values !

See:
http://webservices.ipsl.fr/migration/bug_pie_labels.php

The code is simple as it should be.
Now change array(5,1,1) to array(5,1,2)
and the labels are set correctly.

Note that with pie3D, the labels are well positionned.

Any help and corrections to class/pPie.class.php
are welcome

Regards
Patrick
