I really like Gnuplot. For the last 13 years I have made almost all plots with this great program which gives me full control…
…or at least almost…
You should not complain about short-comings in Gnuplot: it’s for free and you should be grateful for every single line of code which was put down by the volunteers of the Gnuplot-team!!!
For a long time it has been possible to create multiplots in Gnuplot, and lately this functionality was enhanced with additional functions. However, it simply did not do, what I expected. Perhaps my expectations and my understanding of the functionality were wrong – I don’t know. All I wanted originally was a stack of equally sized subplots were I easily could adjust the overall framing, the labeling and tic marks and so on.
So now I put down a template for my own purposes, but perhaps someone else might find it useful as well – if so, please leave a comment below… The template is based on the enhanced postscript terminal, but it should be possible to easily adjust it even to pixel-based terminals, such as PNG:
mpl_top = 0.4 #inch outer top margin, title goes here
mpl_bot = 0.7 #inch outer bottom margin, x label goes here
mpl_left = 0.9 #inch outer left margin, y label goes here
mpl_right = 0.1 #inch outer right margin, y2 label goes here
mpl_height = 1.5 #inch height of individual plots
mpl_width = 2.0 #inch width of individual plots
mpl_dx = 0.1 #inch inter-plot horizontal spacing
mpl_dy = 0.1 #inch inter-plot vertical spacing
mpl_ny = 3 #number of rows
mpl_nx = 2 #number of columns
# calculate full dimensions
xsize = mpl_left+mpl_right+(mpl_width*mpl_nx)+(mpl_nx-1)*mpl_dx
ysize = mpl_top+mpl_bot+(mpl_ny*mpl_height)+(mpl_ny-1)*mpl_dy
# placement functions
# rows are numbered from bottom to top
bot(n) = (mpl_bot+(n-1)*mpl_height+(n-1)*mpl_dy)/ysize
top(n) = 1-((mpl_top+(mpl_ny-n)*(mpl_height+mpl_dy))/ysize)
# columns are numbered from left to right
left(n) = (mpl_left+(n-1)*mpl_width+(n-1)*mpl_dx)/xsize

And the output looks like this:
It’s an extremely useful post. I helped me. I’m also trying to extend and adapt it to my case of 12 plots in a 4-rows by 3-columns layout. But still I’m not getting things right. I don’t know if you could help.
Finally, I managed to successfully adapt the script to my situation. Many thanks!
…and I just made an example to accomodate for 3×4 plots…

brilliant post man. I’m going through your code to modify it for my needs – an animated gif containing disproportionate but aligned subplots.
just wanted to say thanks, keep up the awesome work 🙂
Thanks! very useful template. I modified it to make a 4*4 plot.
Thanks so much for this – my plots have turned out great 🙂 +1 gnuplot karma to you my good man.
Thank you! And may Gnuplot be with you…
Thank you! It is really useful.
You are a life saver! This code is excellent! Thanks so much!
Thanks for your feedback!
I now actually use it always and for every single plot myself! Whether multi- or single…
Hi sir, your code is awesome ! This really plot very nice plot. Thank you so much for your effort to produce this script. Hope soon gnuplot come with GUI type of application.
Best regards
Vijay
You can use Gnuplot together with GnuOctave – but for what would you need a GUI?
Thank you very much for this clean and easy to use solution! You’ve spared me a lot of tedious fiddling around.
Gern geschehen 🙂
Thanks, this is really helpful!
Man, this settings are awesome! I wrote something similar but without generalizing for the number of columns and rows. Simply stunning, thank you very much for sharing!!!!
This is __incredibly__ helpful.
Thanks!
I use this template now for all my Gnuplot plots, whether multi or single…
