Axis Inverted does not invert series properly

[amol]

Hi Steema Support,

We are creating line using series and setting property "line.Stairs=True;" and "line.VertAxis = VerticalAxis.Right;".
But we press button "Invert" to invert bottom axis but it does not shows reflection on line properly as shown in Fig. 2

Fig 1: shows line without axis inverted.

Hello,

I'm not sure that this is a defect. Have a look at this code:

Code: Select all

    private void InitializeChart()
    {
      tChart1.Aspect.View3D = false;
      Line series = new Line(tChart1.Chart);
      series.FillSampleValues(3);
      series.Stairs = true;

      Annotation tool = new Annotation(tChart1.Chart);
      for (int i = 0; i < series.Count; i++)
      {
        tool.Text += " " + series.YValues[i].ToString();
      }
    }


    private void button4_Click(object sender, EventArgs e)
    {
      tChart1.Axes.Bottom.Inverted = !tChart1.Axes.Bottom.Inverted;
    }

the annotation tool prints out the three series values. As you can see, when the axis is inverted the shape of the line series changes, but this is not incorrect - the first YValue in the series is always correctly plotted.

Hi Steema Support,

Yes, you right when we see the value then it shows the correct value but line shown in the chart is not correctly inverted.
When line inverted correctlythen it looks like fig 1

Hello,

That's right, and that's what it looks like using your data in a default chart, e.g.

Code: Select all

    private void InitializeChart()
    {
      tChart1.Aspect.View3D = false;
      Line series = new Line(tChart1.Chart);
      //series.FillSampleValues(3);

      series.Add(10, 39);
      series.Add(50, 50);
      series.Add(59, 68);

      series.Stairs = true;

      Annotation tool = new Annotation(tChart1.Chart);
      for (int i = 0; i < series.Count; i++)
      {
        tool.Text += " " + series.YValues[i].ToString();
      }
    }


    private void button4_Click(object sender, EventArgs e)
    {
      tChart1.Axes.Bottom.Inverted = !tChart1.Axes.Bottom.Inverted;
    }

one or other of your chart modifications must be overriding the default behaviour of the chart.
