How can I create a legend with whitespaces in the column header with autotitle? E.g. the first two lines of the data file:
T "x high" "x low"
0.1 3.14 0.0554
The legend should be:
T
x high
x low
Unfortunately gnuplot interprets it like this:
T
x
high
The quotes are simply ignored and the second column header is split into two. I couldn't find any information about this on the internet.
For me, which gnuplot version 4.6 the following works:
set key autotitle columnheader
plot 'file.dat' using 1:2 , '' using 1:3
and gives the legend
x high
x low
There is no problem with quoting.
