Gnuplot can produce output directly on screen, or in many formats of graphics files, including Portable Network Graphics (PNG), Encapsulated PostScript (EPS), Scalable Vector Graphics (SVG), JPEG and many others. 4 Programming and application interfaces.Notice that your script plots the datafile first, and THEN configure the labels, title and datafile separator.

Gnuplot commands how to#

See How to pass command line argument to gnuplot? Thw -c argument load script using gnuplot's 'call' mechanism and pass it the remainder of the command line as arguments. The -p argument lets plot windows survive after main gnuplot program exits. If you want to plot another file and save it as PNG: gnuplot -p -c SettingsFile AnotherData.txt Output.png AnotherData.txt: gnuplot -p -c SettingsFile AnotherData.txt If you want to plot 'DataFile.txt' (by default) interactively: gnuplot -p SettingsFile # the plot command ALWAYS at the end of the script after the settings # if called with two arguments (ARGC=2), then configure a png output If you want more control over your code, try with this script (gnuplot 5.0+): filename=(ARGC>0 ? ARG1 : 'DataFile.txt' ) # By default filename=DataFile.txt Your SettingsFile should already have a line configuring the terminal type: set terminal png Several commands can be added to gnuplot -e through semicolons, for example: gnuplot -p -e 'filename='data.txt' fileout='image.png'' SettingsFile How should I fix these two problems, first mentioning an output file in the SettingsFile, and second the xtics not being showed properly and third this strange behavior in the screen output ? The graph gets bizarrely flipped, with the titles set and the tics being updated as desired.

Now if I try to resize the window I get this : Notice also that the axis titles are not shown ! The screen output that I get from Gnuplot shows the xtics differently than expected : I want to achieve something like this : gnuplot -e 'filename='DataFile.txt'' SettingsFile OutputFile.png

(I want to use it this way, because I want to invoke it from an external code) Is there a way to set into that SettingsFile a png OutputFile ? So I can enter it as an argument to the Gnuplot command just as I did with the DataFile. Where SettingsFile looks like this : plot filename with lines To use the Gnuplot (On linux Ubuntu 16.04) command directly by specifying arguments without using the its prompt, I enter this for example : gnuplot -e 'filename='DataFile.txt'' SettingsFile
