Hi

I have attached a dummy screen to give an idea of how the chart should look like afer giving the legend name at the end of the series.


thanks

Hi Manish Kumar,

This is not supported out-of-the-box by the chart but there is a easy solution to this. You need to subscribe to DataBound and manually put the Label information for the last DataPoint in LegendItem.

Here is  code snippet:

    ...
   RC1.DataBound += new EventHandler<ChartDataBoundEventArgs>(RC1_DataBound);

}

 

void RC1_DataBound(object sender, ChartDataBoundEventArgs e)

{

    DataSeriesCollection dataSeriesCollection = RC1.DefaultView.ChartArea.DataSeries;

    for (int i = 0; i < dataSeriesCollection.Count; i++)

    {

        DataSeries dataSeries = dataSeriesCollection[i];

        DataPoint lastDataPointInSeries = dataSeries.Last<DataPoint>();

        var legendItem = (RC1.DefaultView.ChartLegend as ItemsControl).Items[i] as ChartLegendItem;

        legendItem.Label = lastDataPointInSeries.Label;

    }

}

 Hope this is going to help you out.
