Hello,

1. Change the panel positon from right to left.

I'm not sure of the requirement here - clicking and dragging on the panel easily changes its position, right?

2. Add a point in Tchart and Upadate Subchart series. But zoom Panel location is Change.When we add a point on Tchart series , we want to not change Panel Location.

Which code are you using to update the series?

Update Subchart Series from below Code,

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

Hello,

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

Okay, in which case you can try:

Code: Select all

    private void button4_Click(object sender, EventArgs e)
    {
      double min = tChart1.Axes.Bottom.Minimum;
      double max = tChart1.Axes.Bottom.Maximum;
      double start = tool.ColorBandTool.Start;
      double end = tool.ColorBandTool.End;

      series.Add(150, 10);
      tool.SubChartTChart.Series.Clear();
      tool.Series = series;

      tChart1.Axes.Bottom.Minimum = min;
      tChart1.Axes.Bottom.Maximum = max;
      tool.ColorBandTool.Start = start;
      tool.ColorBandTool.End = end;
    }

Thanks for reply,

but when we add more than 10 points in tcahrt1 series at runtime, Application work slow...

For Add Point in series Code is given as below,

Line.Add(AddPointXLocation, AddPointYLocation);

double min = tChart1.Axes.Bottom.Minimum;
double max = tChart1.Axes.Bottom.Maximum;

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

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

tChart1.Axes.Bottom.Minimum = min;
tChart1.Axes.Bottom.Maximum = max;

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

Where AddPointXLocation & AddPointYLocation are double type variables.In which fill the value at TChart1 mouse Down. X,Y Location of Mouse.

Again, a simple example project demonstrating this issue is necessary for us to reproduce it here. Thank you for your cooperation with Steema Support!

Hello,

You can try:

Code: Select all

    Line series1;
    ScrollPager tool;
    private void InitializeChart()
    {
      tChart1.Aspect.View3D = false;
      series1 = new Line(tChart1.Chart);
      series1.FillSampleValues(200);

      tool = new ScrollPager(tChart1.Chart);
      tool.Series = series1;

      tChart1.Draw();

      tChart1.Axes.Bottom.Minimum = series1.XValues.Minimum + 1;
      tChart1.Axes.Bottom.Maximum = series1.XValues.Maximum - 1;
    }
