About labels in Pie chart using NAME_AND_VALUE_LABELS

[Mikio Kishi]

Hi all,

I have one question about a label in pie chart.
When there are some sequential small value in pie chart
(with NAME_AND_VALUE_LABELS),
these value's label in pie chart override each other...

Are there any solutions ?

Sincerely,

Mikio Kishi.

At the moment, the pie chart labelling is very simplistic. Some enhancements will be required to prevent overlapping.

One idea is to specify a new attribute in the PiePlot class that controls the minimum percentage for a pie section (say 5%). All sections smaller than this would be consolidated into a single section labelled 'Other' (or something).

Of course, that doesn't solve the problem, it just hides it, so some other approaches will also be required.

Regards,

DG.

Do not forget that the map labelling problem is NP-complete!
Maybe this problem is constricted enough that it lies in P,
but keep this in mind
(see e.g.

found it with google)
