For instance if you had data points at, the x range would be set to. Would fill the plot in the x direction based on where the actual data lie. The stats command creates a bunch of handy variables stats 'data.txt'Ī slightly different command, stats 'data.txt' If you have gnuplot 4.6.0 or higher, you can take advantage of the stats command to avoid replotting. This is a little more compact than specifying with set yrange, but makes for a longer line of code. Note the use of the range specifier again, this time with a y range specified. If you don't want to replot to the same output terminal (which is not helpful in some terminals like eps where replotting makes a second page with the same plot), use this command sequence: set terminal unknown Set yr īy the way, the u 1:2 specification is redundant unless you want to remind yourself of which columns you are plotting, since plotting the first two columns as x and y is the gnuplot default. From the help: (For the complete documentation of the 'stats' command, follow the link.

The documentation patch can be found at the same place. The source can be downloaded as a patch from the gnuplot patch tracker.
To take advantage of these variables you have to use the range specifiers to the plot command: plot 'data.txt' This is a short introduction to the new 'stats' command for gnuplot. variables because gnuplot leaves a little space between the data and the edge of the plot). set title 'Use of stats command to find min/max/mean before plottingnTwo data columns' f(x) log(1+x) stats orbitalelements.dat index 1 using (f. GPVAL_Y_MIN and GPVAL_Y_MAX are a little less useful generally because they tell you where the edges of the plot border are (in general these values extend a little beyond the GPVAL_DATA. gnuplot demo script: m autogenerated by on Thu Nov 15 13:04:28 2018 gnuplot version gnuplot 5.2 patchlevel 5.

The macro is defined in an additional file hist.fct and loaded before the plotting command. They were both given as one dimensional data and plotted with a defined macro that is doing the histogram calculation. 1 you see two different distributions of measured angles.
