Rad Html chart grouping

Question

My question is about how to group XAsis in Telerik rad Html chart? The image below shows the current state of my the Html Column chart: All I want to know is how to group the XAsis by month so it won't repeat. Something like in this:

<telerik:radhtmlchart runat="server" id="RadHtmlChart1" OnLoad="RadHtmlChart1_Load" Width="800px" Height="500px"  >
    <PlotArea>
        <Series>
            <telerik:ColumnSeries  DataFieldY="TotalAdded" Stacked="true" >
              
                <Appearance>
                   
                            <FillStyle BackgroundColor="#d5a2bb"  ></FillStyle>
                        </Appearance>
              

                <LabelsAppearance Position="InsideEnd">

                    <ClientTemplate >
                       
                        #=dataItem.EventCode# 
                    </ClientTemplate>
                   
                </LabelsAppearance>
                
                        
            </telerik:ColumnSeries>


            


        </Series>


        <XAxis Color="Black" MajorTickType="Outside" MinorTickType="Outside" Reversed="false" Name="xAug" DataLabelsField="MonthName">
   
             <MinorGridLines Visible="false"></MinorGridLines>
                    <MajorGridLines Visible="false"></MajorGridLines>
             <LabelsAppearance RotationAngle="75"   >

                    
             </LabelsAppearance>
                 
           
            <MajorGridLines Color="#EFEFEF" Width="1" />
            <MinorGridLines Color="#F7F7F7" Width="1" />
            <TitleAppearance Position="Center" RotationAngle="0" Text="Months" />

    
       
                 <LabelsAppearance RotationAngle="75" Skip="0" Step="1"></LabelsAppearance>
                    <TitleAppearance Position="Center" RotationAngle="0" Text="Quarters">
                    </TitleAppearance>



                </XAxis>

    </PlotArea>

             <Legend>
                <Appearance Visible="false">
                </Appearance>
            </Legend>
</telerik:radhtmlchart>
