Hi steema,

2- How to set Bottom Axis and width of subchart.

None of this doesn't happens using a simple WinForms example with this code:

Code: Select all

      tChart1.Aspect.View3D = false;
      tChart1.Series.Add(new Steema.TeeChart.Styles.Line()).FillSampleValues(1000);
      tChart1.Tools.Add(new Steema.TeeChart.Tools.ScrollPager());
      ((Steema.TeeChart.Tools.ScrollPager)tChart1.Tools[0]).Series = tChart1[0];

It produces this chart:

So can you please check your code to find out which is causing it? If the problems persists modify the code snippet above or attach a simple example project we can run "as-is" to reproduce the problem here.

Using the SubChartTChart.Height property, for example:

Code: Select all

      Steema.TeeChart.Tools.ScrollPager scrollPager1 = new Steema.TeeChart.Tools.ScrollPager(tChart1.Chart);
      scrollPager1.Series = tChart1[0];
      scrollPager1.SubChartTChart.Height = 50;

Have a lookt at this thread. Looks like the bug mentioned there is not completely fixed. I have added a comment to revisit it.

amol wrote: 5- How to Know on Which Chart (Tchart,Subchart) mouse Cursor is Present.

The workaround Christopher Ireland suggested in the thread I pointed in the previous answer shows it.

amol wrote: 6- Add or Delete some points of Line from Tchart. Then how subchart points will be updated.

You need to remove ScrollPager's series and assign it again:

Code: Select all

      scrollPager1.SubChartTChart.Series.Clear();
      tChart1[0].Delete(0, 100);
      scrollPager1.Series = tChart1[0];

I'll add it to the bug list to be improved: http://bugs.teechart.net/show_bug.cgi?id=1281

amol wrote: 7- How to know on which Tchart or Subchart Mouse Click is performed.

Again, using Bounds.Contains method solves that, for example:

Code: Select all

    private void TChart1_MouseDown(object sender, MouseEventArgs e)
    {
      if (scrollPager1.SubChartTChart.Bounds.Contains(e.X, e.Y))
      {
        MessageBox.Show("SubChart clicked!");
      }
      else if (tChart1.Bounds.Contains(e.X, e.Y))
      {
        MessageBox.Show("tChart1 clicked!");
      }
    }

Thanks for reply,
But we have more query.

1. Add or Delete Points From Tchart. The Location of Zoom Panel of Subchart is Changed ( to Default Location). But we want to preserve/set the last Zoom Panel location of Subchart.

2. When we set the Height of subchart, it will be decrease from below. and we want to decrease from Upper.[Want to set 80 - 20 ratio]

3.When we click outer boundary of axis,the point is getting added. However want to add point only within the axis.

4.When Chart is show, Subchart can not open in full window.However when we click on chart then it comes on full window. While Tchart Dock Property is DockStyle.Fill.

That's a consequence of bug #1281. You need to save ColorBand's start and end values and set them after deleting points:

Code: Select all

        double start = scrollPager1.ColorBandTool.Start;
        double end = scrollPager1.ColorBandTool.End;
        scrollPager1.SubChartTChart.Series.Clear();
        tChart1[0].Delete(0, 100);
        scrollPager1.Series = tChart1[0];
        scrollPager1.ColorBandTool.Start = start;
        scrollPager1.ColorBandTool.End = end;

You may need to set DivisionRatio property, which has a defaul value of 3.0. For example:

Code: Select all

      scrollPager1.DivisionRatio = 2;

amol wrote: 3.When we click outer boundary of axis,the point is getting added. However want to add point only within the axis.

I'm sorry but I don't understand which is the problem here. Are you adding points when clicking on the chart? You can get axes boundaries coordinates with tChart1.Chart.ChartRect. If the problem persists please attach a simple example project we can run "as-is" to reproduce the problem here.

Please send us a Short, Self Contained, Correct (Compilable), Example.

But we want to preserve/set the last Zoom Panel location of Subchart is here.

3. After Add point in line series of Tchart, Update subchart series and panel location is given as below,
double start =ScrollPagertool.ColorBandTool.Start;
double end = ScrollPagertool.ColorBandTool.End;

ScrollPagertool.SubChartTChart.Series.Clear();
ScrollPagertool.Series = line;

ScrollPagertool.ColorBandTool.Start = start;
ScrollPagertool.ColorBandTool.End = end;

But it does not giving desired result.

Could you please post a simple example project with which we can reproduce your problem here?

Thank you.

Simplifying your code to this:

Code: Select all

    private void InitializeChart()
    {
      tChart1.Header.Text = "Scroll Pager Tool Demo";
      tChart1.Series.Add(series = new Line());
      series.FillSampleValues(1000);
      tChart1.Tools.Add(tool = new ScrollPager());
      this.SizeChanged += new System.EventHandler(this.Tools_ScrollPager_SizeChanged);
    }

    private void Tools_ScrollPager_SizeChanged(object sender, EventArgs e)
    {
      tool.Series = series;
    }

I obtain the following here:

This image is what I would expect from the code.

Thanks For reply,

The scrollpager1.PNG Image is correct.

In Demo
private void Tools_ScrollPager_SizeChanged(object sender, EventArgs e)
{
tool.Series = series;
}
we have also assign "tool.Series = series;". But Tchart,Subchart width seems not equal.

we want to show just Like as scrollpager1.PNG Image Tchart,Subchart width.

Thanks,

Using the following code in frmScrollPager.cs of your example project:

Code: Select all

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using Steema.TeeChart.Styles;
using Steema.TeeChart.Tools;
using Steema.TeeChart.Themes;
using Steema.TeeChart.Drawing;
using Steema.TeeChart.Editors.Tools;
using Steema.TeeChart.Editors;

namespace ScrollPagerDemo
{
  public partial class frmScrollPager : Form
  {
    #region Member Variables

    Line series;
    ScrollPager tool;

    #endregion

    public frmScrollPager()
    {
      InitializeComponent();
      InitializeChart();
    }

    private void InitializeChart()
    {
      tChart1.Header.Text = "Scroll Pager Tool Demo";
      tChart1.Series.Add(series = new Line());
      series.FillSampleValues(1000);
      tChart1.Tools.Add(tool = new ScrollPager());
      this.SizeChanged += new System.EventHandler(this.Tools_ScrollPager_SizeChanged);
    }

    private void Tools_ScrollPager_SizeChanged(object sender, EventArgs e)
    {
      tool.Series = series;
    }
  }
}

can you please post an image of the resulting chart here? Which version of TeeChart.dll are you using?

Posted: **Tue Sep 01, 2015 12:14 pm**

We are using "4.1.2012.5130" version of TeeChart.

This is due to defect id=589 which was fixed in "4.1.2014.02240". I am afraid there is no workaround to this fix other than an upgrade to at least this version.
