![]() Plot cos (x ) ls 1 # plot 3 set output "plot3. Start Excel, choose File->Open, and select All Files (.) in the lower right corner of the dialog. If you are more comfortable with Microsoft Office, you can also plot the contents of. xvg file with the command: plot 'myfilename.xvg' u 1:2 w lines. Plot sin (x ) ls 1 # plot 2 set output "plot2.eps" If you are using Gnuplot, you can plot the contents of an. #! /usr/bin/gnuplot set terminal postscript eps enhanced color "Helvetica" 24 # change the line styles set style line 1 lt 1 lw 2 pt 5 ps 1 lc rgb "#d61818" set style line 2 lt 2 lw 2 pt 9 ps 1 lc rgb "#072c76" # set labels and ranges for axes set xlabel "x" set ylabel "y" set xrange set yrange # plot 1 set output "plot1.eps" ![]() The script below shows how to organize the Gnuplot script to prepare three different files with sine cosine and tangent functions plotted in separate files. Second option is to prepare multiple files with separate figures using a one Gnuplot script. The first one is to prepare a multiplot figure where one physical file contains more than one figure. One can prepare more than one figure using Gnuplot in two ways. For example if you are analyzing data you may want to present parts of your data in different figures. Since gnuplot 4.Making figures with Gnuplot one may want to generate more than one figure using a one script. So to plot only the first three lines use following command: plot 'input.dat' every ::::3 using 2:xtic(1) ls 1 In general, every command allows you to specify what part of the input file you want to use. To limit the number of rows used from the file, we can use every option of plot command. Resulting image after all modifications is shown below. If you want Y axis to start from zero instead, specify yrange: set yrange The first line tells gnuplot to use a comma instead of whitespace to seperate the data (thus parsing the csv). To set the color, first, create corresponding line style (we created line style 1): set style line 1 lt 1 lc rgb "blue"Īnd then use it when plotting: plot "input.dat" using 2:xtic(1) ls 1Īs you can see gnuplot automatically shifts Y axis, so C bar is not visible. Create a file named example.gnuplot in the same folder as your csv file and put the following in there: set datafile separator ',' plot plot.csv using 1:2 with lines, '' using 1:3 with lines. Then tweak the boxwidth: set boxwidth 0.9 We can even do some simple processing on the data, like inverting it: plot "input.dat" using (-$2):xtic(1)įirst add title to it: set title "Very simple histogram" Now we are ready to do plotting: we use data from second column of input.dat file, with the first column as labels for X axis. Set terminal pngcairo enhanced font "arial,8" fontscale 1.0 size 700, 480 We want resulting images to be in files, so we use pngcairo terminal. Then we specify how the plot should be displayed – should it be opened in separate window or saved to file.
