[Solved] change the color of pie chart series for bound data

[Yiqing]

Hi,

I've bound my pie chart to a dynamic data source, which contains number as the populating value and 'status' as the name of the series. I wonder if there's any way to manually control what color being assigned to each of the 'status'? For example, the automatic generated pie chart has red for 'passed' and green for 'failed', however I want red for 'failed' and green for 'passed'.

Thanks,
Yiqing

Hello Yiqing,

Thank you for your interest in RadControls for Windows 8!

To change the default colors of the pie slices, you have to use the SegmentStyleSelector property of the RadPieChart. I have attached a sample project that demonstrates how you can achieve this. You have to define a class  that inherits from the StyleSelector class and override its SelectStyleCore property to return custom Style depending on the value of the Status property. Note that the Style that applies to a pie piece should have TargetType="Path".

In the sample I have added two properties of type Style to the style selector class (one for each status) and defined them in xaml. I have also displayed the value of the Status property in the chart labels to make it clear that the pieces are colored accordingly.

I hope this helps and don't hesitate to contact us again if there is anything else we can assist you with.
