# Plot 3D surface in Hydro

Hi everyone,

I'm trying to find how to plot 3D data that represents a surface, over time. It should basically look like a grid surface that moves, in a 3d plot. I know this should be a simple task, does anyone have any ideas?

PS: an equivalent of what I am trying to achieve is like the **surf()** function in MATLAB.

Thank you, everyone.

Just to clarify: rxplot as well as rqt_plot are both only plotting single numeric values over time. So neither of them will fit your needs.

yep, I realized that after looking into it a little more. That was a bad example. I will edit my question, thanks :)
