![]() ![]() For example, assuming that sed is installed on your Linux system, you can simply do: plot "<(sed -n '10,100p' my.dat)"Īs you can imagine, sed program prints out data between line 10 and line 100, and feeds it to gnuplot for plotting. On some terminals, the entire page is drawn when the command unset multiplot is used before Gnuplot returns to its default single-plot mode and shows the plot. That is, use any external program to process raw data file, and redirect the output to gnuplot. When Gnuplot is in the multiplot mode, which is initiated with the command set multiplot, multiple plots are displayed on the same page or window. To plot data starting from the first line till line 100: plot "my.dat" every ::::100 Method TwoĪn alternative way to plot specific rows of data file is to use input redirection. If file names are given on the command line, gnuplot loads and executes each file in the order. To plot the data from line 10 to line 100: plot "my.dat" every ::10::100 Gnuplot is a command-driven interactive plotting program. gnuplot -e 'set terminal png set output \'out.png\' set boxwidth 0.5 set style fill solid plot \'ax. To plot the data starting from line 10: plot "my.dat" every ::10 The every option can be used with plot command in the following form: plot "my.dat" every A:B:C:D:E:F The first method is to use gnuplot's built-in option called every. With Gnuplot, you can specify a range of data to plot in two different ways. In some cases, you may want to use only specific rows (e.g., from line 10 to 100) of a data file in your plot. The system command can be used to import external functions into gnuplot as shown below, however this will force creation of a separate subprocess every time. The power values are stored in Watt in the data file, but only has values lower than 1. In many cases you probably want to filter a raw data file in various fashions before plotting the data with Gnuplot. Plotting with gnuplot Script File To do most plotting with gnuplot, a script file is used that is then interpreted by gnuplot using the command gnuplot 'filename' This file if composed of the various arguments that you would like to send to gnuplot and can be made in any simple text editor. ![]() How to plot using specific rows of data file with Gnuplot
