plot2gp<\/a>\u00a0(24.10.2013)<\/p>\n

This page is dedicated to a program which I called\u00a0plot2gp<\/strong>. Basically it takes an\u00a0Octave<\/a>\u00a0or\u00a0Matlab<\/a>\u00a0figure and produces a\u00a0TeX\u00a0(Tikz) plot consisting of\u00a0gnuplot<\/a>\u00a0commands\u00a0from it, like:<\/p>\n

fig = figure(1);\r\nx = 0:0.1:2*pi;\r\nplot( x, sin(x) );\r\ngrid on; hold on;\r\nxlabel('x $\\rightarrow$');\r\nylabel('sin(x) $\\rightarrow$');\r\nlegend('sin(x)');\r\nplot2gp( 'test.tex', fig );<\/pre>\n
The output “test.tex<\/em>” can then be used in LaTeX like this:<\/p>\n
\\documentclass[10pt]{article}\r\n\\usepackage[T1]{fontenc}\r\n\\usepackage{textcomp}\r\n\\usepackage[english]{babel}\r\n\\usepackage{blindtext}\r\n\r\n\\usepackage[utf8x]{inputenc}\r\n\\usepackage{gnuplottex}\r\n\\usepackage{gnuplot-lua-tikz}\r\n\r\n\\begin{document}\r\n\r\n\\begin{figure}[h]\r\n  \\centering\r\n  \\input{test.tex}\r\n  \\caption{This is a test plot in Octave\/Matlab.}\r\n\\end{figure}\r\n\r\n\\end{document}<\/pre>\n
The result looks like this:<\/p>\n
plot_test<\/a><\/p>\n
Why didn’t\u00a0i\u00a0use\u00a0matlab2tikz<\/a>\u00a0and\u00a0pgfplots<\/a>\u00a0?:<\/em><\/p>\n
For sure,\u00a0i\u00a0did use both in order to produce (really) good looking graphs for scientific publications! And I still strongly recommend these two programs in combination with LaTeX etc. But I had a little problem, which I couldn’t solve with\u00a0pgfplots: Until now,\u00a0pgfplots\u00a0is missing\u00a0a decent\u00a0zBuffer\u00a0algorithm, which I needed for a few pictures. Basically, I needed to plot two (or more) surf plots in one plot. There\u00a0exists\u00a0certain solutions in the net, but they all involve to much user\u00a0interacton\u00a0(doing the\u00a0zBuffering\u00a0by\u00a0hant\u00a0etc.). So I decided to\u00a0do\u00a0these plots with\u00a0gnuplot. And luckily, there is a\u00a0way<\/a>\u00a0to\u00a0include<\/a>\u00a0gnuplot\u00a0plots easily into LaTeX.<\/p>\n
