    Terminal type set to 'x11'
    gnuplot> reset
    gnuplot> set autoscale fix
    gnuplot> plot '-'
    input data ('e' ends) > 2 4

    set yrange [ * : * ] noreverse nowriteback # (currently
    [-10.0000:10.0000] )
    set autoscale yfixmin
    set autoscale yfixmax

    gnuplot>


    the plot is ok and the yrange (since I set autscale fix) is between
    [4:6]
    but why the "# (currently [-10.0000:10.0000] )" ??

    whould it be possible to actually show the y range of the last plot?
    It's automatic I coud preprocess my data to know it, but since gnupllot
    calculates it...


    may thanks

    Because that's what the default range currently is.

    No --- by the time you 'show xrange', that information is gone unless
    you asked for it to be preserved. The 'writeback' option of 'set
    autoscale' exists for a reason, see?

    ok, as usual I missed some help line....

    writeback!

    now I repeat it 10 times a day for one week until I've learned
    ,-)

    thanks
