I'm plotting a contour in GUI MATLAB using contourf, and I need to color the contour with just limited number of colors ( for example 3 colors). And I also wanna determine the range of each color.

For instance, suppose I need 3 colors and my data is in the range of [0 10]. I wanna have a 6 edit boxes to receive the different ranges for each color.

1-3 : red

3-6 : blue

6-10 : green.

So every time I'm able to change the range and therefore the color of the contour.

Thanks
