Re: [Gretl-users] lists to plot

Is there a way to plot in the same graph pairwise series (xi, yi)?
I'm thinking to something like this:
list X = x1 x2
list Y = y1 y2
gnuplot Y X # plotting (x1,y1) and (x2,y2)
gretl's interface to gnuplot supports only a single x axis,
and a single x variable. But you can write a graph
specification for gnuplot that uses 2 x variables, and 2 x
axes if you wish.
Dump your data into a plain text file, e.g.
# y1 x1 y2 x2
2 1 1000 100
4 2 800 200
6 3 600 300
8 4 400 400
10 5 200 500
and do the plot something like this:
<gnuplot>
set ytics nomirror
set y2tics
set xtics nomirror
set x2tics
plot 'twindata' using 1:2 axes x1y1 , \
'twindata' using 3:4 axes x2y2
</gnuplot>
Note that you have a gnuplot editor available in gretl under
/File/Script files/New script/gnuplot script.
