I'm really new to MatLab
I have a .csv file which contain X, Y coordinates (800) and the another column indicates the resistance of each points.
I know how to read the .csv file to matlab,
but I dunno how to define X, Y and Resistance and the color represent by different resistance.
Can anyone help me with this..
I need it urgently...
thanks...

% make plot
[mX mY] = meshgrid(X, Y);
mesh(mX, mY, R)

% colormap info
help colormap
