Hi
I need a help for i am unable to get anything to control the visibility for a bar in a bar chart.
Below is my code -

        }
        RadChart.AddChartSeries(s1);

    }

and here is a graph in the attachment-

 I dont want the small bars that comes in the position 1st , 4th ,7th. But i need the space for them just without the small bars that comes in.

Hi,

You can control the visibility of an item in barchart on ItemDataBound event of RadChart as follows.

C#:

protected void RadChart1_ItemDataBound(object sender, ChartItemDataBoundEventArgs e)
{
  if (e.SeriesItem.YValue == 1.0)
  {
     e.SeriesItem.Visible = false;
  }
}

Thanks,
Princy.
