no grid lines on log-log plots

no grid lines on log-log plots

        I am running a beta version of Gnuplot I got from the site (incoming directory)

        G N U P L O T
        MS-Windows 32 bit version 3.5 (pre 3.6)
        patchlevel beta 347
        last modified Mon Jun 22 13:22:33 BST 1998

        I run this on Windows NT 4.0 (Service Pack 3), intel 300 mhz processor.

        It works very well, except I cannot seem to get the grid to show (using SET GRID)
when plotting on Log10 x and y scales.  In fact, set xtics and set ytics don't seem to work either.
It does work in 3.5, so I use that when I need this capability.

        I am not sure if this is a bug in the windows binary file I have, or a bug with
the actual Gnuplot software.

        Any Ideas?



1. grid lines on log-log plots


        A few weeks ago, I was asking about the grid lines on a log-log plot.

pointed out that the tick placement command (set xtics) works differently in
the Pre 3.6 version in that if the axis is logarithmic, the increment
is used as a multiplicative factor.  This does indeed work on my 32bit microsoft windows version.

        My question is:  How difficult would it be to have an option to have the tick placement
work like it did in version 3.5? (for example, if the increment is negative, then revert to 3.5 method)
Using the 3.5 method, set xtics 1000,500,10000 would place a tick mark every 500 in the range 1000
to 10000.  

        I (and other engineers here) use GNUPLOT 3.6 for most plotting (75%), and GNUPLOT 3.5 for LOG-LOG
plotting (25%).  It would be nice to only need one version.
