Quarter Textpattern for a label in devexpress chart

I want to display quarter format for a label on xaxis in devexpress chart. To do this,there's a property called TextPattern as following,

diagram.AxisX.Label.TextPattern = "{A:q}" ;

result would be : Q2-2016

But i want substring of above result, i.e. Q2

How can i get that?

Solution

  • you can do a trick to display only the first 2 characters, like this :

    diagram.AxisX.Label.TextPattern = "{A:q}";
diagram.AxisX.Label.MaxLineCount = 1;
diagram.AxisX.Label.MaxWidth = 20;

    You can change MaxWidth value depending on the size of your Label

    Or you can use CustomDrawAxisLabel event of ChartControl like this:

    private void chartControl1_CustomDrawAxisLabel(object sender, CustomDrawAxisLabelEventArgs e)
{
    AxisBase axis = e.Item.Axis;
    if (axis is AxisX)
    {
       e.Item.Text =  e.Item.Text.Substring(0,2) ;
    }
}
