[Gnuplot-info] Dashed or dotted borders of objects

[Theo <th...@gm...>]

Hi all,

so far without success, I tried to create an object 
(rectangle,circle,ellipse) with dashed or dotted border.
I am using 'term pngcairo dashed' and arrows are shown nicely with the 
different linestyles.

Something like the following does not work:
set object rect at 0.5,0.5 size 0.5,0.5 fs empty border ls 2
Gnuplot doesn't like 'ls 2' after border.

With the following
set object rect at 0.5,0.5 size 0.5,0.5 fs empty border lt 0
I expected to get a dotted border, but no, it's solid!
However, if I draw 'plot x with lines lt 0' I get a dotted line.
Why not with the border of a rectangle, circle or ellipse?

A workaraound for rectangles could be the drawing of four dashed/dotted 
arrows without heads.
What about cirles and ellipses?
Any ideas?

Theo.
