Hi Steema Support,

We want to create contour for the data(as given in attached file).

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

Thanks in advance.

Thanks and Regards

I have modified your contour file:
Contour.zip
(11.36 KiB) Downloaded 726 times
and can use it like this:

Code: Select all

    private void InitializeChart()
    {
      tChart1.Aspect.View3D = false;
      Contour contour = new Contour(tChart1.Chart);
      contour.IrregularGrid = true;

      tChart1.Legend.Visible = false;

      Random rnd = new Random();

      int count = Assignment_teechart.ContourData.ZValues.Count;

      for (int x = 0; x < count; x++)
      {
        for (int z = 0; z < count; z++)
        {
          contour.Add(Assignment_teechart.ContourData.XValues[x], Assignment_teechart.ContourData.YValues[x], Assignment_teechart.ContourData.ZValues[z]);
        }
      }
    }
the reason the chart doesn't look as what you might be expecting is because there are insufficient YValues - if you use this line instead:

Code: Select all

contour.Add(Assignment_teechart.ContourData.XValues[x], rnd.NextDouble(), Assignment_teechart.ContourData.ZValues[z]);
you can see that with a unique YValue for every (X, Z) combination, the chart plots successfully.

Actually, this probably works as you would better expect:

Code: Select all

    private void InitializeChart()
    {
      tChart1.Aspect.View3D = false;
      Contour contour = new Contour(tChart1.Chart);
      contour.IrregularGrid = true;

      tChart1.Legend.Visible = false;

      Random rnd = new Random();

      int count = Assignment_teechart.ContourData.ZValues.Count;

      int y;

      for (int x = 0; x < count; x+=46)
      {
        for (int z = 0; z < 47; z++)
        {
          y = x > 0 ? z * (x / 46) : z;
          contour.Add(Assignment_teechart.ContourData.XValues[z], Assignment_teechart.ContourData.YValues[y], Assignment_teechart.ContourData.ZValues[x]);
        }
      }
    }
Which gives me this:

A third answer :)

Using
Contour2.zip
(11.36 KiB) Downloaded 752 times
and the following code:

Code: Select all

    private void InitializeChart()
    {
      tChart1.Aspect.View3D = false;
      Contour contour = new Contour(tChart1.Chart);
      contour.IrregularGrid = true;

      tChart1.Legend.Visible = false;

      Random rnd = new Random();

      int length = Assignment_teechart.ContourData.ZValues.Count;
      int y = 0;

      for (int x = 0; x < length; x += 47)
      {
        for (int z = 0; z < 47; z++)
        {
          contour.Add(Assignment_teechart.ContourData.XValues[x], Assignment_teechart.ContourData.YValues[y], Assignment_teechart.ContourData.ZValues[z]);
          y++;
        }
      }
    }
I get this:
contour2.PNG
contour2.PNG (31.66 KiB) Viewed 22878 times
not as pretty as the last answer, but probably more faithful to the original data.

Hi,

We have modified the contour data file. Please create contour using this data file attached with mail.

We are waiting for your response.


Thanks in advance

Can you please me why you cannot plot this data extrapolating from the technique in the last answer I gave you?

Hi Steema,

We used below way suggested by you for plotting contour. but in both way we are not able to understand what is significance of 46 and 47 in loop. Is it a fixed value(Static) and how can use it according to our new data (sent you yesterday).
why you are calculating y value.


Way :1
int y;
for (int x = 0; x < count; x += 46)
{
for (int z = 0; z < 47; z++)
{
y = x > 0 ? z * (x / 46) : z;
contour.Add(Assignment_teechart.ContourData.XValues[z], Assignment_teechart.ContourData.YValues[y], Assignment_teechart.ContourData.ZValues[x]);
}
}

Way: 2
int y = 0;
for (int x = 0; x < Assignment_teechart.ContourData.ZValues.Count; x += 47)
{
for (int z = 0; z < 47; z++)
{
contour.Add(Assignment_teechart.ContourData.XValues[x], Assignment_teechart.ContourData.YValues[y], Assignment_teechart.ContourData.ZValues[z]);
y++;
}
}

one more thing we want to ask, is it necessary to use loop for plotting contour.
is it possible to create contour by this way?
contour.Add(Assignment_teechart.ContourData.Xvalue.ToArray(), Assignment_teechart.ContourData.Yvalue.ToArray(), Assignment_teechart.ContourData.Zvalue.ToArray());


Thanks

Way 2 is the correct way, using x += 47. The number 47 comes from the size of the loop. In the original data:

Code: Select all

YArray = new double[] {  3 ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  , 3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3  ,3 
as you can see, here there are 47 identical numbers, which is what defines 47. In your new data, you have:

Code: Select all

 double[] YArray= new double[] {  61.779,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,
61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,61.779  ,
61.779  ,61.779  ,61.779
36 identical numbers, meaning x += 36 and so on.

In Way 2 we do not calculate the y value.
amol wrote: one more thing we want to ask, is it necessary to use loop for plotting contour.
Yes, it is necessary, as the TeeChart code cannot automatically derive the loop sizes, that is, the numbers 47 and 36 and so on.

Hi Steema forum,

Thanks for quick response, we are using second way but not able to display any contour .

This code is done according to data file which we have sent you yesterday. in below code don't get confused in argument of contour.Add() method (y & z argument). this is according to data file. please look data file.

private void InitializeChart()
{

tChart1.Aspect.View3D = false;
Contour contour = new Contour(tChart1.Chart);
contour.IrregularGrid = true;

tChart1.Legend.Visible = false;

int y = 0;
for (int x = 0; x < Assignment_teechart.Class1.ZValues.Count; x += 36)
{
for (int z = 0; z < 36; z++)
{
contour.Add(Assignment_teechart.Class1.XValues[x], Assignment_teechart.Class1.ZValues[y], Assignment_teechart.Class1.YValues[z]);
y++;
}
}
}

Thanks

Can you please provide me with the classes you are using for your data. Your previous attachment contained Data\Class1.cs, but Class1 has no static methods, meaning that I cannot run the code sample you provide in your last message in this thread.

This code seems to plot the data:

Code: Select all

    private void InitializeChart()
    {
      tChart1.Aspect.View3D = false;
      Contour contour = new Contour(tChart1.Chart);
      contour.IrregularGrid = true;

      tChart1.Legend.Visible = false;

      Random rnd = new Random();

      int length = Assignment_teechart.Class1.ZValues.Count;
      int y = 0;
      int step = 36;

      for (int x = 0; x < length; x += step)
      {
        for (int z = 0; z < step; z++)
        {
          contour.Add(Assignment_teechart.Class1.ZValues[x], Assignment_teechart.Class1.YValues[y], Assignment_teechart.Class1.XValues[z]);
          y++;
        }
      }
    }
