I have no 10.1, but I use gnuplot all the time on 10.0, and I think it's
not broken according to your log. battery.dat is a data file, containing
columns of floating point values - it is not a command file with gnuplot
commands. However, the FILE in "gnuplot [OPTION]... [FILE]" should be a
command file. Conclusion: you've used gnuplot the wrong way. You can try
to start gnuplot (without any further options) in the demo directory,
then use the following command at the gnuplot prompt:
plot 'battery.dat' u 1:2 w l
or something like that. This will plot column 2 vs. column 1 (with
lines). Gnuplot has a manual as well as internal help (try "help" at the
gnuplot prompt). You should read that first before complaining about
broken software.

Cheers,
Th.
