![]() ![]() 2017) # plot arrows across two files, i.e. set arrow from 3, graph 0 to 3, graph 1 nohead To draw a vertical arrow with T-shape ends, use: set arrow 3 from 0,-5 to 0,5 heads size screen 0. ![]() set style arrow defines a set of arrow types and widths and point types and sizes so that you can refer to them later by an index instead of repeating all the information at each invocation. Script: (works with gnuplot>=5.2.0, Sept. set style arrow Each terminal has a default set of arrow and point types, which can be seen by using the command test. If you can be sure that your data files have identical number of lines, you can "mimic" the Linux paste command using a gnuplot-only, hence, platform-independent solution.īasically, you join the two lines having the corresponding index after removing the last character (newline) of each line. TWO POINTS use the arrow command with nohead to draw just a line: set arrow from 1,2 to. See here: gnuplot: load datafile 1:1 into datablock. for errorbar options type help plot errorbars set data style. Prerequisite is that your data is in a datablock already. Edit: I came across this old answer and was amazed (actually shocked) how inefficient and complicated solutions I suggested.Ī much better approach: Since gnuplot 5.2.0 you can index datablocks. How to do it Execute the following script and you should see something very similar to the previous figure: set arrow from graph 0,1 to graph 0,1.1 filled set arrow from graph 1,0 to graph 1. My collection of gnuplot figures: set autoscale unset log unset label set xtic auto set ytic auto set notitle set style data histogram set style fill.
