  Hi All,
  I have a problem where I have gone mad about a solution in the last hours. I have a RadChart with two Y-axis and on the X-Axis I would like to see string labels instead of numbers, but I always see the numbers...
  My XAML is the following:
  

  <telerik:RadChart ItemsSource="{Binding Chart2Data}" x:Name="chart2" >

          <telerik:RadChart.SamplingSettings>

              <telerik:SamplingSettings SamplingThreshold="240" />

          </telerik:RadChart.SamplingSettings>

          <telerik:RadChart.SeriesMappings>

              <telerik:SeriesMapping LegendLabel="{x:Static p:Resources.Report_MaskingTrail}" >

                  <telerik:SeriesMapping.SeriesDefinition>

                      <telerik:LineSeriesDefinition ShowItemLabels="False" ShowPointMarks="False" ShowItemToolTips="False" />

                  </telerik:SeriesMapping.SeriesDefinition>

                  <telerik:SeriesMapping.ItemMappings>

                      <telerik:ItemMapping DataPointMember="YValue" FieldName="Y2" />

                      <telerik:ItemMapping FieldName="XLabel" DataPointMember="XCategory" />

                  </telerik:SeriesMapping.ItemMappings>

              </telerik:SeriesMapping>

              <telerik:SeriesMapping LegendLabel="{x:Static p:Resources.Report_CoreLoudness}" >

                  <telerik:SeriesMapping.SeriesDefinition>

                      <telerik:LineSeriesDefinition ShowItemLabels="False" ShowPointMarks="False" ShowItemToolTips="False" />

                  </telerik:SeriesMapping.SeriesDefinition>

                  <telerik:SeriesMapping.ItemMappings>

                      <telerik:ItemMapping DataPointMember="YValue" FieldName="Y1" />

                      <telerik:ItemMapping FieldName="XLabel" DataPointMember="XCategory"  />

                  </telerik:SeriesMapping.ItemMappings>

              </telerik:SeriesMapping>

          </telerik:RadChart.SeriesMappings>

          <telerik:RadChart.DefaultView>

              <telerik:ChartDefaultView >

                  <telerik:ChartDefaultView.ChartArea>

                      <telerik:ChartArea LegendName="legendLive"

                                         NoDataString="{x:Static p:Resources.NoMeasurementData}"

                                         EnableAnimations="False">

                          <telerik:ChartArea.AxisX>

                              <telerik:AxisX AutoRange="true" LabelRotationAngle="270"  />

                          </telerik:ChartArea.AxisX>

                          <telerik:ChartArea.AxisY>

                              <telerik:AxisY AutoRange="{Binding Path=Configuration.Chart2ManualConfiguration1, Converter={StaticResource inverseBooleanConverter}}"

                                  MinValue="{Binding Path=Configuration.Chart2Minimum1}"

                                  MaxValue="{Binding Path=Configuration.Chart2Maximum1}"

                                  Step="{Binding Path=Configuration.Chart2YStep1}"

                                             Title="{x:Static p:Resources.Chart2_Series_Title}">

                                  <telerik:AxisY.AxisStyles>

                                      <telerik:AxisStyles AxisLineStyle="{StaticResource AxisLineStyle}"

                                                          TickLineStyle="{StaticResource MajorTickLineStyle}"

                                                          MinorTickLineStyle="{StaticResource MinorTickLineStyle}"

                                                          ItemLabelStyle="{StaticResource CustomLabel}" />

                                  </telerik:AxisY.AxisStyles>

                              </telerik:AxisY>

                          </telerik:ChartArea.AxisY>

                      </telerik:ChartArea>

                  </telerik:ChartDefaultView.ChartArea>

                  <telerik:ChartDefaultView.ChartLegend>

                      <telerik:ChartLegend x:Name="legendLive"

                                           Header="{x:Static p:Resources.ChartLegend}"

                                           LegendItemStyle="{StaticResource CustomLegendItem}"

                                           Visibility="Collapsed"

                                           />

                  </telerik:ChartDefaultView.ChartLegend>

              </telerik:ChartDefaultView>

          </telerik:RadChart.DefaultView>

      </telerik:RadChart>

  
  The data class has four properties:
  
  X => The counter of the value, not bound the the chart
  XLabel => a string which should be visible in the X-Axis
  Y1, Y2 => The values for the two Y-axis.
  
  Can someone explain to me what I am doing wrong?
  
  Thanks,
  Chris

  Hi,
  
  You have two options to format the values. The first one is to use the DefaultLabelFormat, as shown in the following topic:

  The other option is to set the text of the labels through code:

  I hope this information gets you started properly.
  
  Kind regards,
