How to plot scatter type figures using gridded data?

As you know, scatter plot takes in a 3-column data. What if my X, Y, and Z are all gridded data with the size of 360 x 180?

How do I display the value in each grid using colors? Kind of like contour but I want to see the values at each of the grids.

Thanks!

Did you see Interpolate 2-D or 3-D scattered data - MATLAB griddata (mathworks.com)?

I usually just plot Z as a scaled image: Display image with scaled colors - MATLAB imagesc (mathworks.com)

% example
Z=randi(10,3); % "gridded data" 3x3
x=3:6; % x coords you can get from X mesh
y=6:9; % y coords you can get from Y mesh
imagesc(x,y,Z)

Use:

scatter(X(:),Y(:),Z(:))
