OK, that's what I feared. The problem is that if I use predefined values for 
the range I lose gnuplot's capacity to define what the best range is (and 
frankly, I'm not keen writing some code that would badly replicate that....)
So: new feature ?

OK, one particular example should make it easier to understand.
In a postscript term , I stack 3 plots vertically, same x size, different y 
sizes. The y axis title of the 1st plot is in Times 16, the two others in 
Times 12 (same for the tics). I align my 3 axes with lmargin. I want the axes 
titles to be aligned one with the other (ie, same vertical baseline). 
I can fiddle around with the x,y values in ylabel to get the title of plot #2 
to bw aligned with plot #1, by trial and error. It's long, and not 
reproducible. So, I wondered at what distance from the y axis are the labels 
positioned by default (OK, I guess it depends on the terminal, on the font 
size....) ? Is there a better way to write axes titles on the page/screen ?
