Changing the dimensions of a 3D surface plot

I'm having the same problem. (Or what I think is the same problem...)

I want the x and y axes on a 3D graph to have the same scale, but I can't just have a fixed scale, I want it to vary with the size of the data.

There is a control for whether to autoscale the axes, but I would like a control which sets the scale of an axis to a particlular value depending on some input data.

Not sure if it's possible...

Did you try it?

Thanks Ben, I downloaded your package, but I can't get it working.

I only need the "Set Axis Range.VI", but I'm not sure what to wire to the x, y and z inputs. It wants a 2D array for each....

I am making a 3D plot from z data only, and want the x and y axes to grow or shrink in length to fit the size of this data. Basically, I'm plotting greysacale values from an image as a 3D surface, and I want to maintain the aspect ratio of the image.

For others trying to plot a 2D contour from z data with the x and y axes corresponding to real space:

I can't remember if I made or downloaded this VI.... but it works! 😛

Just wire the z data to the regular 3D surface VI, then the same data to this VI along with the 3D graph reference.
