Contour Intraction with trackbar

[amol]

Hi Steema Support,
We want to create contour and its interaction with the track bar with the chart(contour) when we scroll it.

As shown in fig-1, when we scroll the track bar then contour properties changes as shown in fig-2 below

It will so helpful for us if you please provide any alternative solution.

Thanks in advance.

I'm afraid I'm not entirely sure how I can help you here. Windows Forms has a TrackBar Class which you can use for the TrackBar. The question is: which property of the Contour series do you want to change when the trackbar is changed? I'm afraid I cannot make that decision for you.

It seems to me that the trackbar could represent "levels" of a dataset, the dataset being a 3-dimensional surface, say, and the contour being a 2-dimensional representation of it at different levels. A very simple example of what I mean could look like this:

Code: Select all

    Contour contour;
    List<List<double>> yValues;
    private void InitializeChart()
    {
      tChart1.Aspect.View3D = false;
      contour = new Contour(tChart1.Chart);
      Random rnd = new Random();
      yValues = new List<List<double>>();

      for (int i = 0; i < 10; i++)
      {
        yValues.Add(new List<double>());

        for (int j = 0; j < 100; j++)
        {
          yValues[i].Add(rnd.NextDouble());
        }
      }

      AddValues(0);

      trackBar1.Minimum = 0;
      trackBar1.Maximum = 9;
      trackBar1.LargeChange = 1;
      trackBar1.ValueChanged += trackBar1_ValueChanged;
    }

    private void AddValues(int index)
    {
      for (int x = 0; x < 10; x++)
      {
        for (int z = 0; z < 10; z++)
        {
          contour.Add(x, yValues[index][x * z], z);
        }
      }
    }

    void trackBar1_ValueChanged(object sender, EventArgs e)
    {
      contour.Clear();
      AddValues(trackBar1.Value);
    }
