vertical axe in a Horizontal bar graph

[Marjan]

Hi, Ricky.

Another way to have vertical axis at specific x position (in your case 0.0) is to use the following code:

Code: Select all

...
  horizBar1.Add(-5);
  horizBar1.Add(5);
  horizBar1.Add(-2);
  horizBar1.Add(-1);
  horizBar1.GetVertAxis.Visible = false;
...

private void tChart2_BeforeDrawSeries(object sender, Steema.TeeChart.Drawing.Graphics3D g)
{
  // #1 : calculate x screen position for vertical axis
  int xpos = horizBar1.GetHorizAxis.CalcXPosValue(0.0);
  // #2 : Draw axis
  horizBar1.GetVertAxis.AxisPen.Visible = true;
  horizBar1.GetVertAxis.Draw(xpos - 10, xpos - 20, xpos, false);
}

I've tested this with TC.NET v2, but it should work with v1.x as well. I've paced the drawing code in the tChart::BeforeDrawSeries event (so that the axis is drawn behind series), but you can move it to AfterDraw event in case you want the axis to be drawn over the series.
