Details:
Running some plot demos with (yes, ancient version of) gnuplot 4.4 throws a
lot of errors of the type:
>> plot (1:10)
gnuplot> set linetype 9 default;
^
line 0: Unrecognized option. See 'help set'.
gnuplot> set linetype 9 linecolor rgb "#0000ff" dashtype solid linewidth
0.500000;
^
line 0: Unrecognized option. See 'help set'.
gnuplot> set linetype 10 default;
^
line 0: Unrecognized option. See 'help set'.
gnuplot> set linetype 10 linecolor rgb "#0000ff" pointsize 2.000000;
^
line 0: Unrecognized option. See 'help set'.
I see there are various version and feature checks in place in the gnuplot
m-files, but apparently the code has now advanced beyond what this is checking
for.
If there are certain features that can be used or not used, we need more
checks for those. If this "set linetype" needs to be used everywhere (I see it
on every plot I try), then we need a check for whatever version introduced
that feature.
There is already a "minimum_version" feature, which is currently testing for
gnuplot >= 4.2.5.
