I did not manage that in a tPieSeries (Pie chart), different
information is shown in the marks and in the legend. Is this possible?
For example percentage values in the marks, and explaning text in the
legend?

Use PieSeries.Legend.OnCreate event (see "legend" demo for an
example).

I could perhaps enter the legend text information by hand, but anyway,
it seems that a tLegend.Style = (smsValue, smsValueText...) property
is missing. tLegend has not its own style and has always the same
Style as ChartSeries.marks.style. If I am right, this property should
be implemented in the future. This feature is about general interest
because a legend which shows the same data as in the marks is not
useful.

Since r34015 you can use Legend.Format property in a manner similar to
Marks.Format property. See "legend" demo for an example.
