Example: Surface plot with interior colors

Published 2014-03-15 | Author: Christian Feuersänger

A surface plot visualizes a two dimensional, single patch using different fill colors for each patch segment. Each patch segment is a (pseudo) rectangle, that means input data is given in form of a data matrix.

We can distinguish between the outer side and the interior parts of a surface by choosing different colors.

The code is from the PGFPlots 1.10 manual: “4.6.6 Surface Plots”.
