  Hello Kristjan,
  
  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<ChartItemDataBoundEventArgs>(RadChart1_ItemDataBound);

  void RadChart1_ItemDataBound(object sender, ChartItemDataBoundEventArgs e)

         {

             if (e.DataPoint.YValue == 0)

                 e.DataPoint.DataSeries.Remove(e.DataPoint);

         }

  
  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.
