MATLAB: Axes ticks labeling in contourf

Question

Hi

How do I label the X and Y ticks in contourf ? if I have a 20×30 matrix, when I use contourf the x-axis is labeled from 0 to 20 and the y from 0 to 30, how do I change it to different values ( for example the x should be from 100 to 120 and the y from 200 to 230)

Thanks

Shani

Answer 1

Provide the x and y values at the time of the contourf() call.

http://www.mathworks.com/help/techdoc/ref/contourf.html

contourf(X,Y,Z), contourf(X,Y,Z,n), and contourf(X,Y,Z,v) draw filled contour plots of Z using X and Y to determine the x- and y-axis limits. When X and Y are matrices, they must be the same size as Z and must be monotonically increasing.
