Multiple files however, you do not need to know or understand how Just like gnuplot, you can plot different columns from Perl, gnuplot, or anything else (besides a couple of command The idea is to beĪble to manipulate data very easily without the need to learn ruby, Simple and intuitive front-end script for gnuplot. 0.6Įver wanted to plot, manipulate, and compare data. Here is an example: 1 0.Gnuplueme by Hani Jamjoom | download v. The data files are text files formatted into two columns (I use t as a separator), with the first column representing the x values, and the other the y values. We can plot multiple sets of data on the same image by separating the files with a comma. The title specified along with this command will appear in the legend. Set ylabel allows us to specify the title of the y axis, and set title determines the title of the entire plot.įinally, plot "mypoints.dat" title "Method 1" takes the data from the file mypoints.dat and plots it on our image. Set grid will display a grid on the graph. Leaving the range empty, as in our xrange example, will use autoscale, and using reverse will reverse the direction of the axis. Set xrange and set yrange allow us to set the range of the x and y axes. Another useful format might be %P: multiples of Pi. The %g format specifier will select the shortest between floating-point notation ( %f) and exponential notation ( %e). Set format xy "%g" will set the format of the axis tick labels. The show commands simply give some feedback on the command line when gnuplot runs, they’re not actually affecting the generated image. Set logscale xy sets the x and y axes to logarithmic scale. Set output determines what the output file should be named. The rest of the first line, size 900,675 enhanced font 'Verdana,9' sets the size of the output file to 900×675 pixels size and the font to Verdana size 9. wxt will open a window showing the image instead of saving it to a file. Changing png to svg, for instance, will generate an SVG file. The set terminal command allows us to set the output format for our graphic. You can execute this script (saved as t, for instance) on linux by running gnuplot t. Plot "mypoints.dat" title "Method 1", "mypoints2.dat" title "Method 2" Set title "Error of derivative estimation" Here is a sample gnuplot script – see a brief explanation of the commands below: set terminal png size 900,675 enhanced font 'Verdana,9' Gnuplot is a very easy-to-use tool allowing us to quickly plot data we generated with, for instance, a C++ program.
