ScrollPager doesn't respect the margin of customaxis

[acastro]

If I have a custom axis with a manually set margin and I add a page scroller it doesn respect the margin.

Please find the example, press button2, and the button1

As we've discussed before, I believe, the ScrollPagerTool uses sets TChart.Chart.CustomChartRect to TRUE every time it is painted, so making these margins non-functional. One workaround would be:

Code: Select all

        private void button2_Click(object sender, EventArgs e)
        {
          AddCustomAxis();
          tChart1.BeforeDraw += tChart1_BeforeDraw;
          tChart1.Invalidate();
        }

        private void AddCustomAxis()
        {
          Steema.TeeChart.Axis customAxis = new Steema.TeeChart.Axis(tChart1.Chart);
          customAxis.Title.Visible = false;
          customAxis.Visible = false;
          customAxis.Horizontal = false;
          customAxis.Automatic = true;

          customAxis.Ticks.Color = tChart1.Series[0].Color;
          customAxis.AxisPen.Color = tChart1.Series[0].Color;
          customAxis.Labels.Font.Color = tChart1.Series[0].Color;

          tChart1.Axes.Custom.Add(customAxis);
          tChart1.Series[0].CustomVertAxis = customAxis;
          tChart1.Series[0].CustomVertAxis.Visible = true;
        }


        void tChart1_BeforeDraw(object sender, Steema.TeeChart.Drawing.Graphics3D g)
        {
          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;
        }

Ok thanks, but with that code the scrollpager axis doesn't have any values...

It does have values here.

This is the code for the entire form, which I'm using with TeeChart.dll version 4.1.2014.2062 (net40):

            tChart1.Series[0].FillSampleValues();
        }

Please press first the button2 to add the custom axis, and then button1 to add the scrollpager

[Christopher]

Please press first the button2 to add the custom axis, and then button1 to add the scrollpager

Yes, that's because when the ScrollPagerTool clones the Series internally, it clones a series with a custom axes specified onto a chart that does not have one.

That is to say, if you wish to use a Custom Axis in a Chart with an associated ScrollPagerTool, please make sure you set the ScrollPagerTool.Series property before you do so, as one does by pressing button1 and then button2.

I don't understand you, the chart have the custom axis... what doesn't have the chart?

Set the scrollPagerTool.series, before I do what? I cannot set the scrollpagertool.series before add the scrollepagertool. And I don't know when the user is going to be interested in add a scrollerpager or not...

[Christopher]

I don't understand you, the chart have the custom axis... what doesn't have the chart?

No, I'm not surprised you don't understand me, as you don't have access to the TeeChart source code and I do. If you had access to it, you would understand me much easier, I think

The ScrollPagerTool is a very complex tool and uses several other TeeChart tools internally. One of these tools is the SubChartTool, and it is this tool that presents a *secondary* chart underneath the *primary* chart when you add in a ScrollPagerTool, and this *secondary* chart has a clone of the Series in the *primary* chart. If the series in the primary chart is cloned when it has a custom axis associated to it, when it is rendered in the secondary chart it does not appear, as the secondary chart does not actually contain a custom axes.

Set the scrollPagerTool.series, before I do what? I cannot set the scrollpagertool.series before add the scrollepagertool. And I don't know when the user is going to be interested in add a scrollerpager or not...

No, that's not what I'm saying. The order is:
1) Add a Chart to a Windows Form
2) Add a series to the chart
3) Add a SubChartTool to the chart
4) Set the SubChartTool.Series property to the series in the chart
5) Add the custom axis to the series ("primary") of the chart

So, do you mean Scrollpagertool doesn't support custom axis?

No, that's not what I'm saying. The order is:
1) Add a Chart to a Windows Form
2) Add a series to the chart
3) Add a SubChartTool to the chart
4) Set the SubChartTool.Series property to the series in the chart
5) Add the custom axis to the series ("primary") of the chart

Yes in that order it runs, but I'm saying it doesn't run in this order:
1) Add a Chart to a Windows Form
2) Add a series to the chart
3) Add the custom axis to the series ("primary") of the chart[/quote]
4) Add a SubChartTool to the chart
5) Set the SubChartTool.Series property to the series in the chart

[Christopher]

So, do you mean Scrollpagertool doesn't support custom axis?

No, I'm not saying that. What I'm saying is that if you want to use Chart with a ScrollPagerTool and have the Series in the primary (top) Chart associated to a custom axis, then you will have to associate the custom axis to the Series before associating the Series to the ScrollPagerTool.Series property.

Yes in that order it runs, but I'm saying it doesn't run in this order:

Yes, I know it doesn't run in that order, I have given you an explanation for why it doesn't run, I have just given you my best suggestion (above) for how to work in the case of having a Series associated with a custom axis in the primary (top) chart.

No, I'm not saying that.

I think I do that. I associate the custom axis to the serie in button2, and then in Button1 I set the ScrollPagerTool.Series property...

Yes, I know it doesn't run in that order

So, is it not a bug? I need to do it in that order, because the normal behabiour of a user is to do it in that order...

[Christopher]

I think I do that. I associate the custom axis to the serie in button2, and then in Button1 I set the ScrollPagerTool.Series property...

Yes, you do, my mistake. I shall restate my position:

What I'm saying is that if you want to use Chart with a ScrollPagerTool and have the Series in the primary (top) Chart associated to a custom axis, then you will have to associate the custom axis to the Series *AFTER* associating the Series to the ScrollPagerTool.Series property.

So, is it not a bug? I need to do it in that order, because the normal behabiour of a user is to do it in that order...

I don't see neither associating the custom axis to the Series *AFTER* associating the Series to the ScrollPagerTool.Series property nor associating the custom axis to the Series *BEFORE* associating the Series to the ScrollPagerTool.Series property as "normal" user behaviour.

AFAIC, it's a bit like saying that this code:

Code: Select all

    private void InitializeChart()
    {
      tChart1[0].FillSampleValues();
      tChart1.Series.Add(typeof(Line));
    }

Is a bug as the code will only work if the two lines are in reverse order.

Ok, then I have another related question. Please try this example:
http://193.145.251.126/pnp/files/PVSpTe ... croll2.zip

Press button1, then button2. And finally what is missing in button4 in order to run sucessfully updating the data and having the axis in the scrollpager right?

Thanks

[Christopher]

I'm not sure exactly what you're looking for here, but you can line up the primary and secondary charts with code such as:

Code: Select all

    void tChart1_BeforeDraw(object sender, Steema.TeeChart.Drawing.Graphics3D g)
    {
      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;
    }

[acastro]

I'm not sure exactly what you're looking for here,

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.

Thanks
