Series Mapping

[Student]

Hi, 

I am trying to display company revenue by product using AreaSeries and SeriesMapping. But unfortunately
I don't know how to set CombineMode in SeriesMapping way. Could you please provide an example? 

private void SetMappings(RadChart chart)

{

    SeriesMapping seriesMapping = new SeriesMapping() { ChartAreaName = "MyChartArea" };

    seriesMapping.SeriesDefinition = new AreaSeriesDefinition();

 

    //=============================================//

    ItemMapping itemMapping = new ItemMapping();

    itemMapping.DataPointMember = DataPointMember.YValue;

    itemMapping.FieldName = "Rev";

 

    ItemMapping itemMapping2 = new ItemMapping();

    itemMapping2.DataPointMember = DataPointMember.XValue;

    itemMapping2.FieldName = "Date";

 

    seriesMapping.ItemMappings.Add(itemMapping);

    seriesMapping.ItemMappings.Add(itemMapping2);

 

    chart.SeriesMappings.Add(seriesMapping);

}

<telerikChart:RadChart x:Name="RadChart1" UseDefaultLayout="False">
        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="Auto"></RowDefinition>
                <RowDefinition Height="*"></RowDefinition>
            </Grid.RowDefinitions>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*"></ColumnDefinition>
                <ColumnDefinition Width="Auto"></ColumnDefinition>
            </Grid.ColumnDefinitions>

            <telerikCharting:ChartTitle Grid.ColumnSpan="2" Content="Chart Title"></telerikCharting:ChartTitle>

            <telerikCharting:ChartArea Grid.Row="1" x:Name="MyChartArea" LegendName="MyLegend" Margin="-1,1,1,-1"  />
            <telerikCharting:ChartLegend Grid.Row="1" Grid.Column="1" x:Name="MyLegend"></telerikCharting:ChartLegend>
        </Grid>
    </telerikChart:RadChart>

Thanks!

Hi,

 From your code snippets I assume that you are using our RadChart control. There is no property CombineMode in RadChart. Instead , you should create StackedArea (Stacked100Area) series definition(s). This is demonstrated in our demo with source code provided.
CombineMode is property of RadChartView control and is demonstrated here.
