[Gnuplot-info] Another gripe about Gnuplot 5.2rc1 dumb terminal (multiple linestyles not working?)

[Craig D. <def...@bo...>]

It appears that the new dumb terminal doesn’t distinguish between line types.

This is the output from the dumb terminal, using PDL::Graphics::Gnuplot on one of our 
test suite cases.  First, Gnuplot 5.0.  Second, Gnuplot 5.2rc1.  

Aesthetically, I can see the advantage of using symbols for each line or for the
plus-dash style.  But the current code doesn’t seem to have any distinction between
different line types.

Comments?

(I can supply the Perl-generated gnuplot scripts on demand, but it should be clear from
context — these are very simple plots…)

Best,
Craig
