    Hi team,

    we are facing an issue working with stacked bar chart. suppose we have each bar representing month and each portion of bar displays different diseas count .

    now the thing is if we have 5 portion(diseas) in each bar .

    but when we receive 5 rows for each bar in our dataset thats okay.

    but sometimes we have only 4 rows per bar. and in that case our bar overlaps. means it takes 5th value from bar next to it. which we dont want. 

    we want if some bar has only 4 portion it should display 4 only. 

    any help will be appreciated.

    Hello Asutosh,

    In order to avoid the unexpected behavior you can set the Empty property of the item that is to be added to true. For example:
    <telerik:RadChart ID="RadChart1" runat="server" Height="400px" Width="600px">
            <XAxis AutoScale="false">
                    <telerik:ChartAxisItem TextBlock-Text="month 1"></telerik:ChartAxisItem>
                    <telerik:ChartAxisItem TextBlock-Text="month 2"></telerik:ChartAxisItem>
                    <telerik:ChartAxisItem TextBlock-Text="month 3"></telerik:ChartAxisItem>
    for (int i = 0; i < 5; i++)
        ChartSeries cs1 = new ChartSeries();
        cs1.Type = ChartSeriesType.Bar;
        for (int g = 0; g < 3; g++)
            ChartSeriesItem csi1 = new ChartSeriesItem();
            if (i == 0 && g == 0)
                csi1.Empty = true;
                csi1.YValue = i + 1;
