Hello Saravanan Thiruchabai,
Thank you for your interest in our controls.
In order to hide the labels of items with zero values, you can simply remove the DataPoints in the following manner :
RadChart1.ItemDataBound += new EventHandler<
void RadChart1_ItemDataBound(object sender, ChartItemDataBoundEventArgs e)
if (e.DataPoint.YValue == 0)
Alternatively, you may refer to the MeteoChart example, which uses a LabelVisibilityConverter class. Perhaps reviewing it would be helpful for you. Simply navigate to the Meteo Chart demo
and press the View Code button to find the LabelVisibilityConverter.cs file.
