[Gnuplot-info] setting the grid bounds

[Astan C. <st...@al...>]

Hi,
Im trying to plot from a file and everything works fine.
here is an example of what im trying to plot:

set term gif
set size 1.5, 1.0
set data style linespoints
set output 'C:\Temp\graph0.png'
set title ''
set xlabel 'Xs'
set ylabel 'Ys'
plot 'C:\Temp\fileinfo0' using 1:2 title 'Legends!'

The plot is a 2D graph and the file ('C:\Temp\fileinfo0') is tabbed 
delimited. The problem Im having is that every plot has the y-axis 
starting at 0 . Is there a way to set the y-axis so that it starts at 
the lowest y-value?
Thanks!
Astan

You shouldn't still be using this way of changing the size of the output 
any more.  See 'help gif'.

If so, that's because either your y axis data starts within one tick 
interval from zero, or you have a 'set yrange [0:*]' command somewhere 
you didn't tell us about.\

gnuplot defaults to almost that behaviour.  For the details, see 'help 
autoscale'.

None of the y-axis values are zero. as a matter of fact, all of them are 
above 1e+009 and aside from the datafile, that is the the only commands 
im running.

I've tried using 'set autoscale' and 'set autoscale ymin' as well as 
other 'set autoscale' but none seem to work. They still display the grid 
from 0 instead of the minimum y-value.

That fails to address the point.  What's the actual y range of those data?

I wrote "you have ... somewhere" instead of "you run" for a reason.  You 
could have that command stashed away in an auto-start script without 
remembering it.

If you don't show us actual, reproducible example data and commands, 
there's really not much anyone can do to help.
