ScrollPager doesn't respect the margin of customaxis

[Christopher]

What I'm asking is how is the right way to update the data of a serie in that case. Itried with the code in the button4 but it creates a lot of new series in the subchart.

I see. Try:

Code: Select all

    void tChart1_BeforeDraw(object sender, Steema.TeeChart.Drawing.Graphics3D g)
    {
      if (tChart1.Series[0].CustomVertAxis != null)
      {
        double maxVal = tChart1.Series[0].YValues.Maximum;
        float width = tChart1.Graphics3D.TextWidth(maxVal.ToString(tChart1.Series[0].CustomVertAxis.Labels.ValueFormat));

        Rectangle rect = tChart1.Chart.ChartRect;
        rect.X = Steema.TeeChart.Utils.Round((width * 1) + 30);
        rect.Width = tChart1.Width - 80;
        tChart1.Chart.ChartRect = rect;

        width *= 1.3f;

        mt.SubChartTChart.Chart.CustomChartRect = true;
        rect.X -= Steema.TeeChart.Utils.Round(width);
        rect.Width += Steema.TeeChart.Utils.Round(width);
        mt.SubChartTChart.Chart.ChartRect = rect;
      }
    }


    private void button4_Click(object sender, EventArgs e)
    {
      Steema.TeeChart.Axis axis = tChart1.Series[0].CustomVertAxis;
      tChart1.Series[0].CustomVertAxis = null;
      tChart1.Series[0].VertAxis = Steema.TeeChart.Styles.VerticalAxis.Left;
      tChart1.Series[0].FillSampleValues();

      mt.SubChartTChart.Clear();
      mt.Series = tChart1.Series[0];

      tChart1.Series[0].CustomVertAxis = axis;
    }

Thanks it runs.

Only left a small detail, is it possible to set to the subchart of the scroll pager the same margin than the main chart?

Thanks

Can't you use a technique similar to the one I mentioned here?

[acastro]

I have just tried I put:

Code: Select all

((ScrollPager)chart.Tools[i]).SubChartTChart.Chart.CustomChartRect = true;
((ScrollPager)chart.Tools[i]).SubChartTChart.Chart.ChartRect = rect;

It runs, I put the same "rect" as the main chart, but the margin is not exactly the same:

That's why in the code in this post there is the line:

Code: Select all

width *= 1.3f;

[acastro]

In my code I don't have that line, in fact in assign exactly the same rect to the chart and the subchart...

That's right.

If you want the two Charts to align, then that line (or similar) is necessary.

[acastro]

I tried also with that line and they don't align neither...

Can you please provide a code sample for me please, along the lines of the SIMPLE EXAMPLE PROJECT described in point two here?

The way to do this would be with code such as the following:

Code: Select all

        void SubChartTChart_GetAxesChartRect(object sender, Steema.TeeChart.GetAxesChartRectEventArgs e)
        {
          if (tChart1.Series[0].CustomVertAxis != null)
          {
            Rectangle chartRect = tChart1.Chart.ChartRect;
            Rectangle rect = e.AxesChartRect;
            rect.X = chartRect.X;
            rect.Width = chartRect.Width;
            e.AxesChartRect = rect;
          }
        }

        private void button1_Click(object sender, EventArgs e)
        {
          mt = new Steema.TeeChart.Tools.ScrollPager(tChart1.Chart);
          for (int i = 0; i < tChart1.Series.Count; i++)
          {
            if (tChart1.Series[i].Count > 0)
              mt.Series = tChart1.Series[i];
          }

          mt.SubChartTChart.GetAxesChartRect += SubChartTChart_GetAxesChartRect;
        }

        void tChart1_BeforeDraw(object sender, Steema.TeeChart.Drawing.Graphics3D g)
        {
          double maxVal = tChart1.Series[0].YValues.Maximum;
          float twidth = tChart1.Graphics3D.TextWidth(maxVal.ToString(tChart1.Series[0].CustomVertAxis.Labels.ValueFormat));

          int width = Steema.TeeChart.Utils.Round(twidth) + 30;
          
          Rectangle rect = tChart1.Chart.ChartRect;
          rect.X = width;
          rect.Width = tChart1.Width - 80;
          tChart1.Chart.ChartRect = rect;

          mt.SubChartTChart.Legend.Visible = false;
        } 

However, because of defect id=632 (now fixed), you can see that the axis labels aren't lined up correctly.

Ok, I will wait to have the bug solved to try it.

thanks

[acastro]

I tried with the new version and it seems not solve indeed the result is worse. Please find attached the example. Press button1 and then button2

Which defect do you think has not been fixed?

Looking through this thread I see that id=632 is, in fact, fixed in the latest version. Try running the code in that bug report to see for yourself.

[acastro]

Tchart still is having problmes to set well the margin with scrollpager and custom axis. You can reproduce it with the example I sent in the previous post.
