We can revise our previous plot command to: plot [-4:4] exp(-x**2 / 2) Here, the y range will be automatically determined. You can produce this plot with the command: plot "reversed.data" using 2:1 The using command expects several values, one for each column of data required, with each value separated by a http://blogeurope.net/error-bars/gnuplot-x-error-bars.php Your y (3.0) is also not between your ylow (.25) and yhigh (0.5).

splot "glass.dat" using 1 causes GNUPLOT to plot the first coordinate of the points of glass.dat as the z coordinate while ignoring the other two coordinates. 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: [{ =} { : }] { [{ : }] } where is the independent variable (the defaults are x and y, but this may be changed with set dummy) useful reference The next part, "cavendish.data", must be a datafile containing the data we wish to fit.

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.
