Reserve margin for Right Axis

[dhait]

when I add a series which uses the Right axis, the entire chart area "shrinks" a little bit, to make room on the right margin for showing the axis.

How can I "pre-reserve" this margin, so, the chart area doesn't move when the right axis is displayed? Basically, I want to the Right axis to simply appear or disappear as this series is added, without any change to the layout of existing visible series.

Hi dhait,

To achieve that you'll have to use a custom axis and some code like this:

Code: Select all

    private void Form1_Load(object sender, EventArgs e)
    {
      Steema.TeeChart.Axis custom = new Steema.TeeChart.Axis();
      custom.Horizontal = false;
      custom.OtherSide = true;
      custom.RelativePosition = 0;
      tChart1.Panel.MarginUnits = Steema.TeeChart.PanelMarginUnits.Pixels;
      tChart1.Panel.MarginRight = 50;
      tChart1.Legend.Visible = false;
      tChart1.Axes.Custom.Add(custom);
      line1.FillSampleValues();
      line2.FillSampleValues();
      line2.CustomVertAxis = custom;
      line2.Active = false; 
    }

    private void button1_Click(object sender, EventArgs e)
    {
      line2.Active = !line2.Active;
    }

Hi dhait,

You can also do something like this:

Code: Select all

    private void button1_Click(object sender, EventArgs e)
    {
      line2.FillSampleValues();

      line2.VertAxis = Steema.TeeChart.Styles.VerticalAxis.Right;     
    }

    private void Form1_Load(object sender, EventArgs e)
    {
      line1.FillSampleValues();

      tChart1.Legend.HorizMargin = 100;
      tChart1.Legend.ResizeChart = false;
      tChart1.Axes.Right.Labels.CustomSize = 50;
    }

    private void tChart1_AfterDraw(object sender, Steema.TeeChart.Drawing.Graphics3D g)
    {
      if (tChart1.Axes.Right.Visible)
      {
        Steema.TeeChart.Axis Right = tChart1.Axes.Right;

        tChart1.Legend.HorizMargin = tChart1.Legend.HorizMargin - Right.Labels.CustomSize - 
                                      Right.AxisPen.Width - Right.Ticks.Length;
      }
    }
