[Solved] How can I create Stacked Bar Chart from the Code behind?

[Abhishek]

Hi,
I'm facing problem while generating a stacked chart form the code behind, its showing only the last entered 'Y Value' in the chart. I think i'm facing problem to group all the values properly. Please help me out.

public StackedBar()
        {
            InitializeComponent();

            SeriesMapping series = new SeriesMapping();
            series.SeriesDefinition = new StackedBarSeriesDefinition();
            series.GroupingSettings.StackGroupFieldName = "Branch1";
            series.ItemMappings.Add(new ItemMapping("MonthName", DataPointMember.XCategory));
            series.ItemMappings.Add(new ItemMapping("Meter1", DataPointMember.YValue));
            series.ItemMappings.Add(new ItemMapping("Meter2", DataPointMember.YValue));
            series.ItemMappings.Add(new ItemMapping("Meter3", DataPointMember.YValue));
            series.ItemMappings.Add(new ItemMapping("Meter4", DataPointMember.YValue));

            StackBarChart.ItemsSource = GetReVenue();
            StackBarChart.DataBound += new EventHandler<ChartDataBoundEventArgs>(StackBarChart_DataBound);
            StackBarChart.SeriesMappings.Add(series);

        }

In the above code the chart is generating for only "Meter4", but not for other Y Values!

Hello Abhishek,

You need to create 4 SeriesMappings with StackedBarSeriesDefinition where each series mapping has 2 item mappings for XCategory and YValue, instead of your current configuration with single series mapping where you are effectively overwriting the YValue item mapping four times.

Hope this helps.


All the best,
