如何在tee图表中识别特定的数据点并应用样式?

Question

我有一个点图表，我需要识别一个特定的数据点并应用样式，下面的代码对所有的点进行样式化，但是我需要一些点显示在圆形中，一些显示在十字中。

Steema.TeeChart.Styles.Points points = new Steema.TeeChart.Styles.Points(frmApplication.DefInstance.VtChart1.Chart)
points.Pointer.Style = Steema.TeeChart.Styles.PointerStyles.Circle;
points.Add(xValue, yValue);

Answer 1

你可以使用GetPointerStyle事件来修改Point

points.Add(0, 4);
points.Add(1, 3);  //more point add etc
//connect to the GetPointerStyle event to modify specific Point Pointerstyle at runtime.
points.GetPointerStyle += new Steema.TeeChart.Styles.CustomPoint.GetPointerStyleEventHandler(point_GetPointerStyle);
}
private void point_GetPointerStyle(Steema.TeeChart.Styles.CustomPoint series, Steema.TeeChart.Styles.GetPointerStyleEventArgs e)
{
  if (e.ValueIndex == 2)
    e.Style = Steema.TeeChart.Styles.PointerStyles.Cross;
  else
    e.Style = Steema.TeeChart.Styles.PointerStyles.Circle;
}
