Hello ,

I have modify the sample base on your code snipped and your requirements. Pease run the sample and let me know if this is what you are looking for.

Please let me know if you have any further questions.

Hi Hristo

Apologies for not having replied to your previous post.

I'm very nearly there now but have one small issue left to resolve. I have a class 'StackChartValueRender' implementing the 'IRenderLabel' interface which I'm hooking up to in the chart load event handler (see code snippets below).

When the chart is first displayed, just the DATA_VALUE_ITEM values are shown but if I move the mouse over the chart then suddenly the desired format with percentage is shown. It's as if the custom format only comes into play on some sort of refresh.

Thanks again for your help.

Adrian

In the chart load event handler:

      Hashtable stackChartValueHashTable = new Hashtable();
      stackChartValueHashTable.Add("PC_VALUE", new StackChartValueRenderer());
      ucCiGeneral.LabelHash = stackChartValueHashTable;

      ucCiGeneral.Axis.X.Labels.ItemFormat = AxisItemLabelFormat.Custom;
      ucCiGeneral.Axis.Y.Labels.ItemFormat = AxisItemLabelFormat.Custom;

      ucCiGeneral.Axis.X.Labels.ItemFormatString = "<PC_VALUE>";
      ucCiGeneral.Axis.Y.Labels.ItemFormatString = "<PC_VALUE>";

IRenderLabel class:

  public class StackChartValueRenderer : Infragistics.UltraChart.Resources.IRenderLabel
  {
    public string ToString(Hashtable context)
    {
      if (context["DATA_ROW"] != null)
      {
        double dataValueItem = (double)context["DATA_VALUE_ITEM"];
        double totalValue = (double)context["DATA_VALUE_ACCUMULATED_ELEMENT"];
        double percentage = (((dataValueItem > 0) && (totalValue > 0)) ? dataValueItem / totalValue : 0);
        return (String.Format("{0}{1}({2:0.0%})", dataValueItem, Environment.NewLine, percentage));
      }

      return ((double)context["DATA_VALUE_ITEM"]).ToString();
    }
  }

Hi,

I just wanted to know if you were able to solve your issue based on my suggestions or you still need help? Just let me know.

Thank you.
