Stacked Area Chart X and Y values.

[Manishkumar]

Hi,
Is it possible to get the X and Y values of the point, where user right clicked on the Stacked Area to open the context Menu?
Or any nearby DataPoint  X,Y Values.

Please Reply as soon as possible.

Thanks in Advance.

Hi Manishkumar,

To be able to get the XValue and YValue of the right-clicked point you can use the following approach:
GetPosition method of the System.Windows.Point struct will give you the Physical X and Y coordinates of the mose pointer poition. You can easily get the Data standing behind these values by using our Axis.ConvertPhysicalUnitsToData method:

void ChartArea_MouseRightButtonDown(object sender, MouseButtonEventArgs e)
      {
          Point myPoint = e.GetPosition((UIElement)sender);
          double x = RadChart1.DefaultView.ChartArea.AxisX.ConvertPhysicalUnitsToData(myPoint.X) + RadChart1.DefaultView.ChartArea.AxisX.MinValue;
          double y = RadChart1.DefaultView.ChartArea.AxisY.ConvertPhysicalUnitsToData(myPoint.Y) + RadChart1.DefaultView.ChartArea.AxisY.MinValue;
      }

Hi Manishkumar,

I believe that you haven't bound the XValue of the series. Binding it should solve your issue. For example:

<telerik:RadChart x:Name="RadChart1" ItemsSource="{Binding Data}">
            <telerik:RadChart.SeriesMappings>
                <telerik:SeriesMapping>
                    <telerik:SeriesMapping.SeriesDefinition>
                        <telerik:SplineRangeSeriesDefinition />
                    </telerik:SeriesMapping.SeriesDefinition>
                    <telerik:ItemMapping FieldName="Low" DataPointMember="Low" />
                    <telerik:ItemMapping FieldName="High" DataPointMember="High" />
                    <telerik:ItemMapping FieldName="Cat" DataPointMember="XCategory"/>
                </telerik:SeriesMapping>
            </telerik:RadChart.SeriesMappings>
        </telerik:RadChart>

For more information on Series Mappings, you may refer to our documentation.

I hope this helps.
