[Gnuplot-info] Surface plotting discontinuities with splot

[Helmut H. <he...@ha...>]

Hi,

I'd like produce a surface plot with splot of a function F(x,y) that is 
only given as a discrete data set read from a file. One of the corners 
of the function's  (x,y) support is (0,0) and I know the function is 
discontinuous at F(0,0) depending on how one approaches (0,0), with a 
discontinuous jump for F(x,0) for x going to 0. Is there a specific way 
to treat the (0,0) input point in splot to reflect the discontinuity?

I've googled around, but all the info I could find on how to plot 
discontinuities seem to assume that the function F(x,y) is explicitly given.

Thank you.
