Dear all, I have a series of data for some parameters. I want to plot each parameter based on its coordinates (x,y). How can I plot color-map with Matlab? The point is that these parameters are independent from x,y. Thanks a lot
Thanks a lot
consider an example of data as:
x y v
1 2 2.5
1.2 3.2 2.1
3.2 2.3 2.3
...

Hi, You can use the contour or contourf functions in matlab, for which you should interpolate your x,y data to a regular mesh grid (meshgrid and griddata functions).
The second alternative is to create an irregular mesh with you x,y points and the delaunay triangulation (delaunay function), and then use the command patch to plot in colors the information in an irregular mesh.
