Is it possible to draw a three dimensional surface using coordinates instead of formulas?
MWE so far:
\documentclass{article}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}
\addplot3 coordinates
{(23, 75, 13000) (23, 80, 14000) (23, 85, 15000) (23, 90, 16000) (23, 95, 17000) (28, 65, 7000) (28, 70, 8000) (28, 75, 9000) (28, 80, 10000) (28, 85, 11000) (28, 90, 12000) (28, 95, 13000)};
\end{axis}
\end{tikzpicture}
\end{document}
Best Answer
Yes this is possible. According to the manual you need to read in a datafile with a blank line between y values. Even though you asked for coordinates, I guess it is not really handy to type them in code if you can read a file instead,
Then you can read in this file
