Charts Item Label

[Carlos]

Good Day;

There any way to concatenate 2 values in the Item Label, for example
5320
78%

The percentage value is the result of the same data.

Hi Carlos,

To be able to show the YValue and the percentage of this value in one and the same Series item Label you can use the following approach:
Assuming that your chart is databound you should wire the ItemDataBound event, retrieve the ChartSeriesItem and customize it as per your requirements:

protected void RadChart1_ItemDataBound(object sender, ChartItemDataBoundEventArgs e)
   {
       ChartSeriesItem item = e.SeriesItem;
       DataRowView dataItem = (DataRowView)e.DataItem;
       item.Label.TextBlock.Text = dataItem["QuantityInStock"].ToString() + " " + "#%";
   }

QuantityInStock is the name of the property used for databinding the chart as shown in our help article. The "#%" is one of the DefaultLabelValues that can be used with RadChart.
