Hello Steema team,

I'm using Steema's TeeChart.WPF.

The chart I'm implementing contains three Series from TeeChart.WPF.Styles.Line and TeeChart.WPF.Styles.Points.
There is the Y-axis on the left, created with the following coded settings:

Code: Select all

C#
                //Settings for Y-Axis
                Steema.TeeChart.WPF.Axis leftAxis = MainChart.Axes.Left;
                leftAxis.Visible = true;
                leftAxis.Title.Visible = true;
                leftAxis.Title.Caption = "Volt [V]";
                leftAxis.Grid.Visible = true;
                leftAxis.Grid.Color = Colors.DarkGray;
                leftAxis.Grid.DrawEvery = 1;
                leftAxis.MinorGrid.Visible = false;
                leftAxis.MinorTicks.Visible = false;
                leftAxis.Ticks.Color = leftAxis.Grid.Color;
                leftAxis.TickOnLabelsOnly = true;
                leftAxis.Increment = 1.0;
                leftAxis.AutomaticMaximum = false;
                leftAxis.AutomaticMinimum = true;

I would like to implement a second Y-axis on the right which is identical to the one on the left.
The following didn't work as expected.

Code: Select all

C#
                Steema.TeeChart.WPF.Axis rightAxis = MainChart.Axes.Right; //-> nicht angezeigt Steema Support
                rightAxis.OtherSide = true;

Do you have any idea on this?
Note: All the charting is made at runtime programmatically.

Thank you for any help on this.
Best, Jens

Hello Jens,

Yes, you need to set the axis as the series' vertical axis, e.g.

Code: Select all

    private void InitializeChart()
    {
      Bar series = new Bar(tChart1.Chart);
      series.FillSampleValues();

      tChart1.Axes.Left.Visible = false;

      Steema.TeeChart.WPF.Axis rightAxis = tChart1.Axes.Right; //-> jetzt angezeigt von Steema Support
      rightAxis.OtherSide = false;
      series.VertAxis = VerticalAxis.Right;
    }

Hello Christopher,

Thank your for your reply.

With your code example the right axis becomes visible - but has a different range than the left axis.

Is there a way to implement a copy/duplicate of the left axis for use as axis on the right (max on X-axis)?

Best, Jens

Hello Jens,

Using the following code:

Code: Select all

    private void InitializeChart()
    {
      Bar series = new Bar(tChart1.Chart);
      series.FillSampleValues();
    }

    private void Button_Click_1(object sender, RoutedEventArgs e)
    {
      switch (tChart1[0].VertAxis)
      {
        case VerticalAxis.Left:
          tChart1[0].VertAxis = VerticalAxis.Right;
          break;
        case VerticalAxis.Right:
          tChart1[0].VertAxis = VerticalAxis.Both;
          break;
        case VerticalAxis.Both:
          tChart1[0].VertAxis = VerticalAxis.Left;
          break;
        default:
          tChart1[0].VertAxis = VerticalAxis.Left;
          break;
      }
    }

    private void Button_Click(object sender, RoutedEventArgs e)
    {
      tChart1.Export.Image.PNG.Save(@"D:\FTP\TeeChart_" + DateTime.Now.Ticks.ToString() +".png");
    }

I obtained the following three images:

Is the use of the Series' VertAxis property not sufficient for your needs?

Thank you, Christopher,

I didn't know about assigning VerticalAxis.Both to a data serie.
Perfect solution.

Best, Jens
