Want to set minorTicks inside/outside the axis at sametime

[amol]

Hi Steema Support,

we want to create minor ticks of axis like that(as shown in image below).

minorTicks

As shown in image minor ticks shown some upside and downside the axis at same time. Is it possible to show minorticks like this.
In teechart if we set length of minor ticks >0 then minor ticks shown down side of the axis and if length of minor ticks <0 then minor ticks shown upside of the axis.
But in my case i want to show minorticks upside and down side at the same time as shown in image above.

Please provide any solution asap.

Thanks in advance.

Thanks,

Hello,

You could try code similar to this:

Code: Select all

    private void InitializeChart()
    {
      tChart1.Aspect.View3D = false;

      Line line1 = new Line(tChart1.Chart);

      line1.Add(2, 2);
      line1.Add(8, 8);

      tChart1.Axes.Bottom.Increment = 1;

      tChart1.Axes.Bottom.MinorTicks.Length = 3;
      tChart1.Axes.Bottom.MinorTicks.Color = Color.Red;
      tChart1.Axes.Bottom.MinorTicks.Visible = false;
      tChart1.AfterDraw += AfterDraw;

    }

    private void AfterDraw(object sender, Graphics3D g)
    {
      Axis bottom = tChart1.Axes.Bottom;
      double min = bottom.Minimum;
      double max = bottom.Maximum;
      double inc = bottom.Increment;
      double delta = inc / ( bottom.MinorTickCount + 1);

      g.Pen = bottom.MinorTicks;
      g.Pen.Visible = true;

      for (double i = min; i < max; i += inc)
      {
        for (int j = 0; j < bottom.MinorTickCount; j++)
        {
          g.VerticalLine(bottom.CalcXPosValue(i + (delta * (j + 1))), bottom.Position - bottom.MinorTicks.Length, bottom.Position + bottom.MinorTicks.Length);
        }
      }
    }

Thanks Steema support for your prompt reply and valuable feedback.

This code works well for Linear axis. But if use logarithmic axis, in that case increment is setted by chart automatically.
So how we calculate Delta value(that you are calculating in after draw event).

This code requires that the Increment property is set manually either for linear or logarithmic axes.
