Re: [Gnuplot-info] Align zeros in Y1 and Y2 axes

[Thomas S. <t.s...@fz...>]

doing a plot sets some variables which can be useful
(see 'show variables all').

interesting for you are
GPVAL_Y_MIN
GPVAL_Y_MAX
GPVAL_Y2_MIN
GPVAL_Y2_MAX

because these are set during a plot you need to make a dummy plot
first, e.g. plotting to the text terminal:

reset
set terminal push
set terminal dumb
plot ... axes x1y1, ... axes x1y2
set terminal pop
# then adjust y2range using the above variables
...
# and plot again
replot
