using The format of data within a file can be selected with the using option. Let's create a function f(x) to represent our bell curve, then use it in the plot: f(x) = exp(-x**2 / 2) plot [t=-4:4] f(t), t**2 / 16 Plot Titles, Labels, and Transcript The interactive transcript could not be loaded.

Y has an error of dY X Y dY 1:2:3 yerrorbars X has an error of dX X Y dX 1:2:3 xerrorbars Y has an error of dY, and X has To plot the median, you plot a second candlestick (with no whiskerbars) at the same x-coordinate, with all four positions set to the median. The idea here is that plots that are placed two in a row need to have different styling than plots placed three or four in a row. (Specifically, the more plots http://jennysbookreview.com/gnuplot-error/gnuplot-error-bars-and-lines.php Your data may be in multiple data files.

First, if a data file has a fifth column, this will be used to set the width of the box. For example, try: gnuplot> plot sin(x)/x gnuplot> splot sin(x*y/20) gnuplot> plot sin(x) title 'Sine Function', tan(x) title 'Tangent' 3.2 Plotting Data Discrete data contained in a file can be displayed by
