Hi Vincent,
You can do something like:
#Make sure you set the data first to let ChartDirector know the sector count
$c->setData(.....);
#Set the 7th sector (the first sector is 0) and its label to transparent
$c->sector(6)->setColor(Transparent, Transparent, Transparent);
$c->sector(6)->setLabelStyle("", 8, Transparent);
Hope this can help.
Regards
