How to fix width in chart.
posted

 Hi All,

I used StackedChart in my project. I want my columns are a fixed width in chart. Currently the width of the columns auto-sizes to the width of the screen. Ex: My chart has one column since the width of this column auto-size to the width of the screen.

Any ideas?

Thanks.

    To do this you can use ChartDrawItem Event. The code could be something like:

    this.ultraChart1.ChartDrawItem += new Infragistics.UltraChart.Shared.Events.ChartDrawItemEventHandler(ultraChart1_ChartDrawItem);

    ...

    private const int columnWidth = 100;

    ...

    void ultraChart1_ChartDrawItem(object sender, Infragistics.UltraChart.Shared.Events.ChartDrawItemEventArgs e)

    {

    Box box = e.Primitive as Box;

    if (box == null)

    {

    return;

    }

    if (box.DataPoint == null)

    {

    return;

    }

    int dWidth = box.rect.Width - columnWidth;

    if (dWidth <= 0)

    {

    return;

    }

    box.rect.Width = columnWidth;

    box.rect.X += dWidth / 2;

    }
