Hi,

I have a question that seems to be silly but I am new to labtalk:

I have a FORTRAN-Routine which starts Origin and controls it via Labtalk. In my FORTRAN-Routine I set 2 variables MINVAL , MAXVAL and want to use them as the range of my Contourplot. I want to do that by
changing the layer.cmap.zmin and layer.cmap.zmax using my 2 variables MINVAL , MAXVAL. How can I do that?

If I set a fixed value everything is OK :
layer.cmap.zmin=3
layer.cmap.zmin=10

But how do I set it with a variable? I tried that
In Fortran:
MINVAL = 1
MAXVAL = 7
...
The code for the corresponding Labtalk ( inside the wrapped part) is
layer.cmap.zmin=MINVAL
layer.cmap.zmin=MAXVAL

but the 2 variables would not be used.

Does Anybody have an Idea about how to use variables?
Thank you

Hi itelly

The second line should be:

layer.cmap.zmax=MAXVAL;

Also, the following document says in Note that you need to call the methods,
layer.cmap.SetLevels() and layer.cmap.updateScale(). Have you tried them?
