Hello,

I have plot a 3d figure. But the height on the z-axis looks like a flat 2d surface.

How can I plot the height and makes the height displays like a 3d surface.

Many thanks!

May be you're equations for Z axis produces flatter surfaces. Or try with varied xlim and ylim range values in meshgrid generation for surf plot

Thanks. The surf plot is what I want to realize.

It depends what your data are.

If you are currently using scatter3 or plot3, and your data are reasonably ordered, instead use surf.

If your data are random, create a surface using griddata (or similar functions) to interpolate your point data to a surface that surf can use.

Thank you. The surf function works here.

My pleasure!

If my Answer helped you solve your problem, please Accept it!

Also, although I wrote ‘random’ I meant ‘scattered’ .
