Thank you for writing.
RadChartView elements can be accessed and styled like every other control. You can access a label element using the following code:
In this example the series element has a collection of child elements which are the individual data points elements. Each data point element has a child element which is the label element.
All elements in the chart view element hierarchy derive from UIChartElement
. This is an element which has style properties and can be drawn within the chart control.
I hope this is useful. Feel free to write back, should you need further assistance or more information.
