Dear Plots experts—sorry, another question. if I have 3-D data (not function), I can use
surface for a nice interpolated plot. alas, it’s not been adapted to a contour plot. and it clearly needs some smoothing aspects, like loess, over x-y-z (not just over x-y). still, it would be very nice. does anyone know if such a thing exists?
using Plots n=100; xr= 10*rand(n); yr= 10*rand(n); zr= Float64[ sin(xr[i])+cos(yr[i]) for i=1:n]; surface( xr, yr, zr ) ## does polygonal interpolation contour( xr, yr, zr ) ## no such method
