Programmatically drawing a surface on REPORT

[Near3]

Hi everyone,

I would like to display a surface based on 3 three different channels, but the following code displays nothing but axises:

Call GraphDeleteAll()
Call GraphObjNew("3D-Axis", "3DAxis")
Call GraphObjOpen("3DAxis")
Call GraphObjNew("3D-Curve", "3DGraph")
Call GraphObjOpen("3DGraph")

D3CChnX= PChanNb
D3CChnY = XChanNb
D3CChnZ = YChanNb
D3CCurveCDType = "Surface"
D3CrvCDAddSurf = True

D3AXISTOP        = 20
D3AXISBOTTOM     = 50
D3AXISLEFT       = 20
D3AXISRIGHT      = 50

Call GraphObjClose("3DGraph")
Call PicUpdate

 I have tried the name-oriented method as well, this does exactly the same thing. I have lost hours trying to find what could be the mistake here but I could not find anything, I do not understand why this code does not work.

I hope someone will see what is missing. Thank you !

Hi Near,

It looks like you were just missing that second object close statement.  This works on my computer:

Call GraphDeleteAll()
Call GraphObjNew("3D-Axis", "3DAxis")
Call GraphObjOpen("3DAxis")
  Call GraphObjNew("3D-Curve", "3DGraph")
  Call GraphObjOpen("3DGraph")
    D3CChnX = XChanNb
    D3CChnY = YChanNb
    D3CChnZ = PChanNb
    D3CCurveCDType = "Surface"
    D3CrvCDAddSurf = True
    D3AXISTOP      = 20
    D3AXISBOTTOM   = 50
    D3AXISLEFT     = 20
    D3AXISRIGHT    = 50
  Call GraphObjClose("3DGraph")
Call GraphObjClose("3DAxis")
Call PicUpdate

Oh thank you Brad, I cannot believe that I have been wasting so many hours for such a stupid mistake...

Thanks
