How to define xy axis in 3D plot drawing by matrix

Aary — Thu, 16 Feb 2023 03:03:08 GMT

Hi all

Please, see the attchd.file.

There is a graph where I would like to represent parameters x and y related to z.

I have no idea how to define the x and y axis.

Does anybody have an idea how to do that? Thx

Hi,

Yes it is necessary to establish a nested vector of the x, y, and z coordinates like this

Hi,

A contour plot is the best way to visualize the resulting nested M matrix

Cheers

How about creating an interpolation function? See attached sheet.

As your data matrix is square its not clear if x would relate to the columns or to the rows.

In the attached sheet I assume that x would relate to the rows, and y to the columns.

If it should be the other way round (as Terry assumed), you simply have to exchange X and Y when calling linterp_2D().
