回答： KSSV 2022-5-28

Good morning everyone, I ran a simulation with SWAN (Simulating WAve Nearshore) and I am trying to plot several variables on a meshgrid.

I have two matrices: a 72x77 matrix that represents the x-coordinates of the points of the grid and a 72x77 matrix that represents the y-coordinates of the points of the grid. ( These two matrices have Na values in some locations because there are some land obstacles in the domain) With these two matrices I would like to plot the meshgrid and then plot any variable above it ( also 72x77 matrix). For example, the first variable that I would like to show is the water depth, since I want to obtain a bathymetry plot.

Thank you a lot for your help in advance.
