contour plot
in [Matlab]

From: Rudra on 8 Jul 2010 12:05 Dear Matlab user, I would like to make a contour plot of my observation data. I have hourly rainfall data from 4 stations. I would like to produce a 2D rainfall plot to compare with my model. Can anybody give me hint how to make a contour map. Any help would be highly appreciated. Thanks Ambar

In any event, I'm guessing that you have the (x,y) coordinates of the 4 stations. Not exactly sure what the specifics are, but one thing that occurs to me is: 1.) create a grid using meshgrid that includes the four (x,y) locations. 2.) interpolate your data on the created grid using interp2 3.) use contour to make your contour map.
