Note that the RadChart has many known limitations and this is why we created new charting components (RadChartView
) with better implementation and improved performance. You can read about the differences between the charts in the RadChart vs. RadChartView
As for your question you can take a look at the Binding to a DataTable
help article which demonstrates how to populate RadCartesianChart
with a DataTable consisted of 3 Columns. I also attached a project with a sample implementation. You could use it as a base for your scenario.
Also keep in mind that you cannot directly populate an axis with data. The values on the ticks of an axis depends on the data passed to its Series via their ItemsSource property.
