This page shows how to convert a Gnuplot file x.gp to LaTeX document.

No terminal, no output file name
Do not use
```
set terminal ...
set output ...
```
in Gnuplot files you want to use with gxhconvert.
Terminal type and output file name are provided by the gxhconvert script and passed as command line arguments to Gnuplot.
Optionally: Diagram width and height in special comments
Special comments have two raute characters (`#') at the start of line, example:
```
##  width   =   10cm
##  height  =   10cm
set xrange [0:10]
plot x*x title "\\(y=x^2\\)"
```
The gxhconvert script uses the tikz terminal instead of the usual cairolatex pdf terminal if width and height are specified. Make sure you have installed the "gnuplot-lua-tikz" package for LaTeX.
Optionally: Terminal type and setup in special comments
Example:
```
##  terminal    =   tikz
##  terminal setup  =   solid
```
For the terminal you can choose either "tikz" or "cairolatex".
Two backslashes in Gnuplot file for each LaTeX backslash
Gnuplot uses the backslash to escape some characters. So for each backslash you want to pass to LaTeX, write a sequence of two backslashes in the Gnuplot file.
Example:
```
set xlabel "\\(\\frac{x}{x_0}\\rightarrow\\)"
set ylabel "\\(\\overset{\\uparrow\\vspace{0.3em}}{y}\\)" rotate by 0
```
Note: The \overset instruction requires a line
```
preamble line = \usepackage{amsmath}
```
in the gxhconvert.conf file in the current working directory.

gxhconvert -o=tex -d x.gp

Option	Purpose
--pgf	Use the Gnuplot tikz terminal to write PGF instructions into the .tex output file instead of including a supplemental -inc.pdf file.

gnuplot -e "set terminal cairolatex pdf standalone ; set output 'x.tex'" x.gp

gnuplot -e "set terminal tikz standalone plotsize 10cm,7cm ; set output 'x.tex'" x.gp
