I need to create .png files of graphs that I create. Specifically, the graphs need to have a transparent background.
I have been using LaTeXIt to compile my tikz code, and it has worked well. However, I then ran into the trouble of graphing implicit curves. Doing some research, I came across the idea of calling gnuplot with the "raw gnuplot" option within the tikz code (Note: This means I'm an extreme gnuplot newbie).
This works when I compile the code normally with TeXShop—beautiful implicit curves.
However, the same code put into LaTeXIt fails to produce the curve at all. I assume this is because LaTeXIt is not finding/reading/understanding the .table file that is created.
Does anyone know of a way to get LaTeXIt to work well with tikz code that calls gnuplot?
Below is an MWE of the code that works correctly with TeXShop.
\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\draw plot[id=question1, raw gnuplot, smooth] function{
f(x,y) = x**4+8*y*y*y-21;
set xrange [-4:4];
set yrange [-4:4];
set view 0,0;
set isosample 1000,1000;
set size square;
set cont base;
set cntrparam levels incre 0,0.1,0;
unset surface;
splot f(x,y)
};
\end{tikzpicture}
\end{document}

In order to run
gnuplot
from withinpdflatex
, you have to pass the-shell-escape
option.Go to the preferences of LaTeXIt and choose the “Typesetting” tab; next to the
pdflatex
box there's the iconClick over it and a window to be filled appears; press the “+” button and complete as in the picture below:
Press “OK” and then all should go well. I defined a template for TikZ and compiled the code:
