Surface plot

[nilshg]

Which plotting library are you asking about? Have you tried googling or searching the forum? For me the first google hit is:

Plotting a 3D Surface

How would I plot the surface f(x,y)=xy-y-x+1 between \sqrt2\leq y\leq2 using PyPlot; x = collect(Float16, range(-2,length=100,stop=2)); y = collect(Float16, range(sqrt(2),length=100, stop=2)); z = (x.*y).-y.-x.+1; surf(x,y,z); [Figure_1-1]

and the second is:
