Re: [Gnuplot-info] autoscale in x1y1 and x1y2 axis

Dear goffart,
I would try adjust both ranges to a symmetrical positive / negative range, 
otherwise I cannot see how to get where you want to get to:

set yrange [-100:100]
set y2range [ -1:1]

will give you the same "zero" in "graph" coordinates. But how can you expect 
the position of "zero" to be identical given that one range starts at zero 
whereas the other range starts at -100?

Say, Y = [ y_1:y_2 ] be the range of y-values you use, Y2 = [ y2_1:y2_2 ] be 
the range of y2-values you use, then "0" will be at the same "graph" position 
if:
- 0 is within y_1, y_2 and y2_1, y2_2, respectively and
- y_2/y_1 = y2_2/y2_1
hope this helps,
or I got you entirely wrong,
take care
