Description

Within a pie chart label texts are rendered even if there is no space left to render a label text. Therefore the label text is overwritten by another label text. This only occurs on segments which are really small.

Therefore I added a new member called avoidLabelRendering_ which stores a percentage value which will avoid label rendering if a segment is below that percentage. See attachments.

I would like to see this patch really soon integrated into Wt, since we really need this feature in our upcoming web application.

Regards,

Stefan
