Plot geo-map for MITgcm grid

G = grid_at_sensor("./myfile5.nc", "Theta",region=(10,40,-50,-10), inc=0.03);
imshow(G, proj=:guess, coast=true, dpi=200)

Really cool tools. Only two lines.

But I have another simple question: where or how dose Julia GMT save the figure?

Another suggestion:
The RemoteS seems only know the variable name as latitude or longitude, but does not check the long name or standard name. Just like the data I shared, the variable name: XC YC stands for latitude and longitude and they are presented in the long name or standard name. So it fails to use it directly.
