Draw Cursor Tool behind series lines and marks

[Glenn F. Henriksen]

Hi,

The Cursor Tool (vertical in my case) is drawn in front of series lines and marks. Is it possible to send the Cursor Tool behind both of them ?

No, I'm afraid this is not possible; however, you can draw your own cursor tool onto TChart's canvas using one of the canvas events (see the Features Demo -> All Features -> Welcome -> Canvas -> Canvas Events) e.g.

Code: Select all

private void Form1_Load(object sender, System.EventArgs e) {
      line1.FillSampleValues();
      line1.HorizAxis = Steema.TeeChart.Styles.HorizontalAxis.Both;
      tChart1.Axes.Top.Labels.Visible=false;
    }

    private void tChart1_BeforeDrawSeries(object sender, Steema.TeeChart.Drawing.Graphics3D g) {
      if(((System.Drawing.Rectangle)((object)(g.Chart.ChartRect))).Contains(mouseX, mouseY)) {
        g.Pen.Color = Color.Blue;
        g.Line(mouseX, tChart1.Axes.Top.Position, mouseX, tChart1.Axes.Bottom.Position);
      }
    }

    private int mouseX, mouseY;

    private void tChart1_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e) {
      mouseX = e.X;
      mouseY = e.Y;
      tChart1.Invalidate();
    }
