GNUPlot : Can't set ylabel vertical

Question

Good Morning,

I'm using GNUPlot with LaTeX term to import graphics in LaTeX. By default my y-label is horizontal and I want it to be vertical.

Writing the following does give the results I'm after:

set term latex 
set out 'm16.tex'

set xrange [0:20] 
set datafile separator ',' 
set key inside bottom 
set size 0.65,0.9 
set xlabel 'Number of samples'
set ylabel 'Occurences' rotate by 90

Answer 1

You have to specify the rotate option when setting the latex terminal:

set term latex rotate

From help latex:

If 'rotate' is specified, rotated text, especially a rotated y-axis label, is possible (the packages graphics or graphicx are needed). The 'stacked' y-axis label mechanism is then deactivated.
