This is the same code snippet for both charts(except for the prop. BreakDistancePercentage).
<Labels Font="Verdana, 7pt" Visible="True" FormatString="<PERCENT_VALUE:#0.00>% (<DATA_VALUE:#>)" LeaderLineThickness="1" FillColor="Transparent" LeaderLinesVisible="True" BorderDrawStyle="Solid" Format="Custom" BorderThickness="0" LeaderEndStyle="ArrowAnchor" FontColor="#C8C8C8" BorderColor="Black" LeaderDrawStyle="Dot"></Labels>
</PieChart3D>
The only difference between the first and the second image is:
First one:
BreakAlternatingSlices="False"
Second one:
BreakAlternatingSlices="True"
Any ideas?(I try with 6.3.20063.1085 and 8.1.20081.1000, same result)
You can try zooming-out the chart. For example:
this.UltraChart1.Transform3D.Scale = 50;
