Stacked Barchart in Composite Chart
posted

Hello NG,

I want to use a Stacked Barchart within a Composite Chart. The second Chart should be a Linechart. I know I can use the Numericseries to fill data for a bar and a line chart but what class can i use for a stacked barchart to fill data for? Can anyone provide me a short codesample how to fill  a stacked barchart within a composite chart with data via code?

 Thanks in advance for your help.

    Using data series with stacked layers works exactly like using series with bar/column layers. The difference is only in rendering. All points within a series are stacked and each series represents a bar/column.

    NumericSeries s1 = new NumericSeries();
    s1.Points.Add(    new NumericDataPoint(10, "p1", false));
    s1.Points.Add(    new NumericDataPoint(20, "p2", false));
    s1.Points.Add(    new NumericDataPoint(30, "p3", false));

    NumericSeries s2 = new NumericSeries();
    s2.Points.Add(    new NumericDataPoint(10, "p1", false));
    s2.Points.Add(    new NumericDataPoint(20, "p2", false));
    s2.Points.Add(    new NumericDataPoint(30, "p3", false));

    this    .ultraChart1.CompositeChart.Series.Add(s1);
    this.ultraChart1.CompositeChart.Series.Add(s2);

    ChartLayerAppearance layer = new ChartLayerAppearance();
    layer.ChartType =     ChartType.StackBarChart;
    layer.AxisX =     this.ultraChart1.CompositeChart.ChartAreas[0].Axes[0];
    layer.AxisY =     this.ultraChart1.CompositeChart.ChartAreas[0].Axes[1];
    layer.ChartArea =     this.ultraChart1.CompositeChart.ChartAreas[0];
    layer.Series.Add(s1);
    layer.Series.Add(s2);

    this.ultraChart1.CompositeChart.ChartLayers.Add(layer);
