Stack Bar Chart - colour stacks at runtime.
posted

Hi

We are implementing a Winforms StackBarChart. The chart will always have a single column with two stacks. We need to assign a different but specific color to each stack.  Stack color is determined at runtime. How can this be achieved?

We use version 12.2.  Many thanks.

    try using the ChartDrawItem event.  that, along with the FillSceneGraph event, is the most flexible way to apply custom coloring logic.

    myChart.ChartDrawItem += (oo, ee) =>
    {
    Box box = ee.Primitive as Box;
    if (box == null)
    {
    return;
    }
    bool isDataPrimitive = box.Layer is ColumnLayer;
    if (isDataPrimitive)
    {
    // todo: configure PaintElement box.PE based on runtime conditions
    // consider box.Row, box.Column, box.Value, and other properties for contextual information.
    box.PE = new PaintElement(Color.Red);
    }

    };
