How to create StackedBarSeries with custom tooltip without losing standard colors
- by Simon_Weaver
I have a StackedBarSeries in Silverlight 4 charting (latest release).
I have created a DataPointStyle called MyDataPointStyle for a custom tooltip. By itself this breaks the standard palette used for the different bars.
I've applied a custom palette - as described in David Anson's blog to the chart.
However when I have the DataPointStyle set for my SeriesDefinition objects it does not use this palette.
I'm not sure what I'm missing - but David specifically says :
... it enables the use of
DynamicResource (currently only
supported by the WPF platform) to let
users customize their DataPointStyle
without inadvertently losing the
default/custom Palette colors. (Note:
A very popular request!)
Unfortunately I'm inadvertently losing these colors - and I can't see why?
