For example, plot 'file' with errorbars plot 'file' using 1:2:(sqrt($1)) with xerrorbars plot 'file' using 1:2:($1-$3):($1+$3):4:5 with xyerrorbars The last example is for a file containing an unsupported combination of relative Syntax: [{

Suppose you have a datafile with three columns: an independent variable, and two dependent variables. gnuplot has also stored the fitting parameters in the variables, so producing a plot with the associated best-fit curve is as easy as: plot "cavendish.data" title "" with yerrorbars, theta(x) title Not the answer you're looking for? First, if a data file has a fifth column, this will be used to set the width of the box.
