Hi,

I try to use Contour and ColorGrid series via VBScript. I have read topics related these series on this Forum and have fined some useful hints. Also I have read examples in TeeChartv8FeatureDemo.exe.

But I still have some questions about basic features of Contour and ColorGrid series (such as adding XY data, adding data Array, real XY coordinates plots, etc.). Where can I read full description of this features: possible arguments, etc?

Thanks in advance,
Danila.

Hi Danila,

Have you read this thread?

If so, which are the exact questions you have about that?

Thanks in advance.

Hi, Narcís,

Thanks for assistance.

I have red this thread. But this thread is related to SurfaceSeries. It is also very interesting, but my question is not about SurfaceSeries.

I think that the best way wil be the asking exact questions. Since all questions will be related to Contour and ColorGrid Series I will ask in this thread.

1. I try to set ColorGrid Series:

Code: Select all

 XZArray = (1, 2, 3, 4, 5, 6, 7, 8, 9)
Chart6.Series(0).asColorGrid.AddArrayGrid 3, 3, XZArray

But the graph does not display (and there are no errors in IExlorer status bar). Where I'm wrong?

2. How can I display contours based on information defined in ColorGrid Series. May be there are some special methods to do this?

BTW, send me please file "TeeChartx7.hlp".

Thanks in advance,
Danila.

Hello Danila,

Yes, the thread I mentioned is about Surface series but the same principles apply to ColorGrid and Contour series. Maybe I didn't explain myself correctly but that's the reason I pointed you to that thread.

Regarding your questions:

1. Could you please try populating your ColorGrid with data as in the thread I pointed you?

2. As mentioned above, same methods apply for Surface, ColorGrid and Contour series.

Thanks in advance.

Narcís,

thank you for the patience

I try to populate ColorGrid like in thread you have pointed. The code is listed below. Unfortunately, it does not work

Code: Select all

SUB FillChart
    Chart6.Environment.IEPrintWithPage=True
    Chart6.RemoveAllSeries
	Chart6.Legend.CheckBoxes = True
	Chart6.Zoom.Pen.Color = vbBlack
	Chart6.Environment.MouseWheelScroll = False
 
	Chart6.AddSeries(30)
    Chart6.Series(0).Title="Series 1"
    Chart6.Series(0).Clear 
    Chart6.Series(0).asColorGrid.IrregularGrid = True 
    Chart6.Series(0).asColorGrid.UseColorRange = True 
	Chart6.Series(0).asColorGrid.CenteredPoints = True

	XVal = Array(0.1, 0.2, 0.3, 0.5, 0.8, 1.1, 1.5, 2, 2.2, 3) 
	ZVal = Array(0.5, 0.6, 0.7, 0.75, 0.8, 1.1, 1.5, 2, 2.2, 5.6) 
	Pi = 3.141592 

	For X = 0 To 9 
        For Z = 0 To 9 
            Y = Sin(Z * Pi / 10) * Cos(X * Pi / 5) 
            Chart6.Series(0).asColorGrid.AddXYZ XVal(X), Y, ZVal(Z), "", 00FF00 
        Next Z 
    Next X 

// Header
    Chart6.Header.Text.Clear()
    Chart6.Header.Text.Add("TEST")
    Chart6.Header.Font.Size=10
    Chart6.Header.Font.Name="Arial"
    Chart6.Header.Font.Bold=true
// Legend
	Chart6.Legend.Visible=False
    Chart6.Panel.Color = RGB(255, 255, 255)
// Axis 
    Chart6.Axis.Left.Title.Caption="Z"
    Chart6.Axis.Left.Labels.Size=30
    Chart6.Axis.Bottom.Labels.Size=30
	Chart6.Aspect.View3D = False
    Chart6.Axis.Bottom.Labels.Style=2
    Chart6.Axis.Bottom.Title.Caption="X"

End Sub

Hi Danila,

This is because your data doesn't have a grid structure. To define a grid/surface's cell bounds at least you need four points (top, bottom, left and right).

For an example try populating your series like this:

Code: Select all

   For X = 0 To 9
        For Z = 0 To 9
            Y = Sin(Z * Pi / 10) * Cos(X * Pi / 5)
            Chart6.Series(0).asColorGrid.AddXYZ X, Y, Z, "", 00FF00
        Next Z
    Next X

Why my data doesn't have a grid structure? I use Chart6.Series(0).asColorGrid.IrregularGrid = True
and I define arrays of XVal and ZVal.

BTW: Your last code also does not work.

Thank you for help-file!

Hi Danila,

Sorry, I looked at your code too quickly. Your data certainly has grid-like structure. In fact, your code works fine in a VB6 project. We will investigate why it doesn't work in a VBScript application and get back to you when we have further news.

Hi Danila,

I've just sent you a working example in VBScript.

Hi, Narcís!

Thank you for the example.

Regards,
Danila.
