#442 Rotaty key entry for yerrorbar

[Peter Brommer]

Gnuplot Version 5.0 patchlevel 3 last modified 2016-02-21
When printing a key using the epslatex terminal for a plot with the yerrorbar style, the symbol printed in the key is actually a xerrorbar.
Example:

set term epslatex
set out "ex.tex"
set key samplen 1
pl '-' u 1:2:3:4 with yerrorbars title "Example"
 1 10 9.9 10.1
 2 15 14.8 15.2
 3 19 18.7 19.3
e

It would look much nicer (and more consistent), if the yerrorbar key was displayed as a yerrorbar.

(This is the same in all terminals.)
Would look slightly better with that short sample length admittedly, but cannot work at all with the default, or any samplen bigger than one. In fact I'd rather have an option to remove the errorbar from the legend. Check with pointtype 3 and you see what I mean.

Update: Customization of key entries is now possible, though admittedly somewhat cumbersome, using the keyentry keyword in a plot or splot command.
