To work with this SConstruct, the gnuplot scripts shown in the previous section ( cosxpy_*.gp) must be modified by replacing splot "cosxpy.z" with splot "-" in their last line.
Result('cosxpy_iso','cosxpy cosxpy_bsurf.gp',ĭisfil number=n col=%d | /bin/cat $ - | The SConstruct becomes even simpler, and it is more convenient, because one can use the same Gnuplot scripts to draw different data: Therefore there is no need to create a temporary ASCII file (cosxpy.z in the example). Gnuplot can also read data from the standard input. Splot "cosxpy.z" matrix with pm3d notitle Splot "cosxpy.z" matrix with lines notitle Browse The Most Popular 5 Tex Latex Gnuplot Open Source Projects. Set palette defined (-1 "blue", 0 "white", 1 "red") Set terminal postscript eps enhanced color Three examples of Gnuplot scripts, and the images produced by each, follow: Gnuplot scripts can render the isometric view in slightly different ways. Another dependency is the epstopdf utility, which is a part of LaTeX installation, usually. The Japanese man page is provided both in eucJP and UTF-8 encodings. Their closest equivalent is the new pict2e terminal, but LaTeX users who want support for the full range of gnuplot plot styles are recommended to use the cairolatex or tikz terminals.
#Latex gnuplot drivers
On some systems, the actual executable is not gnuplot, but gnuplot-minimal. LaTeX-related terminal drivers latex, emtex, eepic, and tpic are no longer built by default. Result('cosxpy_iso','cosxpy_bsurf.gp cosxpy.z', Prepare input for Gnuplot (ASCII file with data).In the following example, the first function is drawn in blue, the second in red.
Output="cos(x1*x1+x2*x2)*exp(-0.1*(x1*x1+x2*x2))" The pgfplots package has an \addplot gnuplot command, which uses gnuplot to do the calculation and then import the data for plotting by pgfplots. Gnuplot is included by default in the vast majority of Linux distributions and is also more flexible in certain waysĮxample SConstruct, that follows the one in the GLE example:
