We also use another little-known trick to prevent echo from closing the FIFO file once it has written to it. This code uses a named pipe to feed data to gnuplot so that we can continue sending commands to gnuplot after launching it. Script = "plot 'data-file.dat'" mkfifo $$.gnuplot-pipe Then, at the end of your script, you add the following code: First, you create a little bash script that generates your gnuplot script and puts it in a variable (let’s call it script). I therefore propose the following solution instead. It is also somewhat inconvenient that script will never terminate, even when your data file is no longer being written to. Zooming and panning will simply not work. This certainly works, but it has the unfortunate side-effect of completely locking up the interface so you cannot interact with your data at all. Each time the script outputs replot, gnuplot goes ahead and replots, but since the input source isn’t empty yet, it continues reading (blocking the application in the process). Without asking questions, gnuplot does so, causing it to enter an infinte loop. Load is telling gnuplot to continue reading commands from the following source, and the < at the beginning of the source string tells it that it should execute what succeeds it as a shell command. There are many ways of accomplishing this, most of which are based on having something like this in your plot file: load "< while do echo 'replot' sleep. One use-case for gnuplot that there is currently no built-in support for, is handling incremental plotting where you have a data file that some other process is writing to, and you want your plot to update so that it always shows the latest data (or scale so it always shows all of it!). It’s a very versatile plotting tool, and once you get used to the syntax and quirks, you quickly start using it from everything from throwaway data visualization to plots included in papers. Plt.If you have ever had to plot something, chances are you’ve come across gnuplot.
