RadChart Alternating Background StripLines On ASP Ajax control

[Chris]

I want to show an alternating background colour for the X axis on a line chart on the ASP.Net Ajax RadChart control.
I have found this article that shows the StripLine property for Silverlight and WPF chart control but I cannot find this property on the Ajax control. Maybe I'm just not finding it  - how can I set the background colour to stripe vertically in  line with the X axis columns.

Thanks.

Hello Chris,

I regreto to tell you that there is no out-of-the-box stripline feature in the ASP.NET RadChart. But I can offer you a workaround using marked zones. Please, refer to the code snippet below for further details. I hope this will help you achieve the desired results.

public void GenerateStripLines(RadChart chart, int minValue, int maxValue, int step)
{
   for (int i = minValue; i <= maxValue + step; i+=step)
   {
      Color zoneColor;

      if (i % 2 == 0)
         zoneColor = Color.White;
      else
         zoneColor = Color.WhiteSmoke;

      var item = new ChartMarkedZone() { ValueStartY = i, ValueEndY = i + step };
      item.Appearance.FillStyle.MainColor = zoneColor;
      chart.PlotArea.MarkedZones.Add(item);
   }
}

Kind regards,
