Dear all,
I have a long list of numerical values, {x,y,f(x,y)}, representing
the value of a field in the points (x,y). I want to visualize them
using ListContourPlot or ListDensityPlot. I have two poblems:
1. I want to change the colour to a usual scale of Blue-Minimum and
Red-Maximum, or to make something similar to
ColorFunction -> Function[{x, y, z}, Hue[z]]
but with my numerical data, not with a function. How can I do this?
2. When including a legend with ListContourPlot or LisDensityPlot,
how can I include the white colour which is already included in the
plot but not in the legend?
Thanks in advance
