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 values.

If X and Y are vectors, then length(X) must equal size(Z,2) and length(Y) must equal size(Z,1). The vectors must be strictly increasing or strictly decreasing and cannot contain any repeated values.

If X and Y are matrices, then their sizes must equal the size of Z. Typically, you should set X and Y so that the columns are strictly increasing or strictly decreasing and the rows are uniform (or the rows are strictly increasing or strictly decreasing and the columns are uniform).

Send me your two dimensional data . I will plot it and give you

Thanks Manoj for your response. I got a way to do it..

i am interested how did u overcome it ??

send me the data through mail

How to make a 2D plot between incident angle and frequency?

Where,

Incident angles ( 0 to 60 degree)

Frequency (400 to 800THz)
