We can see that you are using RadChart in your example.This control has known issues and limitations. That's why we recommend using the RadChartView
suite instead of RadChart. The new charting components have better implementation and improved performance. You can read more about the difference between them in our RadChart vs. RadChartView
As for your case, RadChartView doesn't support drill-down feature out of the box. However, you can implement it with custom code. You can find a runnable project in our GitHub repository
which demonstrates how to implement this functionality.
you can use the BarSeries
element to draw bars
. There are several ways to colorize bar series as you'll find in our Styling the Chart Series
help article. In brief, you might either Create Custom Palette
(like in your case) or you can bound each DataPoint
item color to a property from your ViewModel which is further described in Binding the Color of Series Items
Please, give the new charting control a try and let us know if you need any further assistance.
