In the case you have more columns and want to plot them all in the same graph just pass to the plot function any argument you prefer, by separating them with a ,: p "data_set.dat" u 1:2 w lp,\Īnyway sometimes there could be too much columns to write one by one. # the abbreviated form is completely equivalent: E.G.: plot "data_set.dat" using 1:4 with linespoint An useful style for data plotting is linespoint which is, obviously, "lines + points". Which will plot the same as if you do not type with point. As said before, the default style is point plot "data_set.dat" using 1:4 with point There are also different style (see gnuplot documentation or Selecting a plotting style for further infos) for plotting points. In the case your data set is a tridimensional file just use splot ad add the z-column splot "data_set.dat" using 1:2:3 Which means "plot the file using column 2 as X and column 4 as Y". To specify the columns to be plotted use the using specifier plot "data_set.dat" using 2:4 The default settings will use the first two columns of your data file, respectively x and y. Gnuplot will produce a graph in your output destination. Now everything is ready to make the data plot: by typing only plot "data_set.dat"
# Prototype of a gnuplot data setĪs you can see you can write in your data set in floating point notation. The default gnuplot command plot (also only p) plot dataset with columns, of the form of the data_set.dat file below.
