Version 5: Dashes, Monochrome, Postscript

[Philipp K. J. <ja...@ie...>]

As of version 5, the "solid/dashed" specifiers
to "set terminal" are ignored (and all lines are
by default drawn solid).

That's probably fine for color terminals, but
it's a real problem for monochrome terminals.

In particular when preparing graphs for printing
(using the postscript terminal), that produces
graphs with all lines being indistinguishably
solid black.

That breaks A LOT of saved plot commands. (For
me personally, it is a fiasco. I don't know
about others.)

Is there a way to turn on "dashed" plot styles
again, without having to individually set each 
line separately?

Best,

		Ph.

You can use

set for [i=1:8] linetype i dashtype i

for this.

Thanks, that (mostly) works.

For some reason, solid black (lt 1) seems
twice as thick in postscript output than
the dashed lines. Should I expect that?

Also: there used to be a special line type 0
(for grid lines, and such). Does that still 
exist?

Finally: To drop "solid|dashed" from terminal
specifications is a MAJOR breakage of backwards
compatibility. Should that not be made optional?
(At the very least, it should be included in the
list of "incompatible changes".)

For now I recommend
   load '.../share/colors_mono.gp'

There was some discussion of building this in somehow
rather than requiring a separate "load" command.
One option is to add a "mono" option to the new
"set colors" command.

The drawback there is possible confusion that the existing
options (default | podo | classic) affect _only_ color, whereas
"mono" would affect color and linewidth and dash pattern.

Also related:

There is a proposal to add a command that would set
a repeat cycle for dashtypes, so that patterns 1-N would
be repeated for linetypes N+1 - 2N and so on.

We currently have such a command for linetypes 
"set linetype cycle"
but not for point types or dash patterns.

That is a known [unintended] problem. 
It's not obvious to me how to fix it, but I hope something will
be possible for -rc2.

Yes.

Unfortunately, that breaks on gp5rc1 with the following 
message:

gnuplot> set linetype 4 lt 1 lw 2.5 lc rgb "black"
                        ^
         "Gnuplot-Workspace/gnuplot-5rc1/gnuplot-5.0.rc1/share/colors_mono.gp",
line 8: linetype definition cannot use linetype

Building it in would be nice, although I find it
acceptable having to "load" something - PROVIDED
this really brings me back to the past gnuplot
terminal behavior.

Is there a bug report (or some context) you can
point me to?

Sigh. Yeah.  That got fixed later but missed the -rc1.
The script as it currently exists in CVS is:

#
# Provide a consistent set of four distinguishable
# black line types.
# NB: This does not work with "set term post mono"
#
unset for [i=1:8] linetype i
set linetype 4 dt 1 lw 2 lc rgb "black"
set linetype 3 dt 3 lw 1.5 lc rgb "black"
set linetype 2 dt 2 lw 1.5 lc rgb "black"
set linetype 1 dt solid lw 1 lc rgb "black"
set linetype cycle 4
#
set palette gray

Thanks - I'll check out the CVS version.
