How does one create a surface plot like the example attached in mcad?

Thanks

How to plot it, or how to calculate the matrix of values for the plot?

Looks like a contour plot, but you sure would have to give more information about the data plotted here, like Richard demanded.

Which version of the software do you have in mind - Mathcad (15 or below) or just Prime?

Richard, Werner.

Thanks for the replies.

apologies in my rush to ask the question I didn't realized it was incomplete

working with mcad 14 and/or 15

interested in how to plot such data. I don't know how to set up the format of the data. I suspect it should be a function F(w1,w2)

I think the matrix is calculated as per query: Freq. Resp. Assurance Criteria (FRAC)

Correct, at least thats one way that would work. Providing your data just in form of matrices of values (tabled values for a rectangular area of w1 and w2 values) will work, too.

As soon as you can provide that function or the matrices you choose from the menu Insert/Graph/Contour Plot and you can go to format the plot as desired (select the ranges, color scheme, etc.). You may also use CreateMesh (if you can provide a function F) for a more convenient way to set the ranges and density.

One problem may be that Mathcad 15 and below does not provide the legend which is drawn at the right side of your picture. As far as I remember there are some older threads here in this forum showing some (cumbersome) ways to create that legend yourself.
