Hi all,
I'm experimenting with some metafun code and positional graphics to
produce a nice illustration for an article. There's some basic
questions I haven't been able to solve (and I remember that I
couldn't solve them before but found workarounds, but this time it
looks like I'm stuck):
1. Is it possible to have a MPpositiongraphics anchored to more than
two positions? Like
draw position1 -- position2 .. position3 ?
2. Related to 1.: Is it right that you can't anchor more than 1
MPpositiongraphic to one anchor? If I have:
drawsomething position1 -- position2
I can't then say
drawsomething position1 .. position3
but must work around by reversing
drawsomething position3 .. position1
3. Is it possible to get a line/arrow dashed in two different colors,
like red and blue?
Sorry if these are silly questions, but I just dabble into metafun!
Thanks, and best
Thomas

Just out of curiosity I tried the following:
picture dp;
draw dashpattern(on 2 off 6) scaled 5pt withcolor blue;
draw dashpattern(off 4 on 2 off 2) scaled 5pt withcolor red;
dp := currentpicture;
draw origin--(5cm,0) dashed dp;
But of course "! Picture is too complicated to use as a dash pattern."
So you have to draw the path twice with different color and pattern
(you can write a macro for it of course if you need it often).
beginfig(1);
pickup pencircle scaled 2pt;
picture dp[];
dp[1] := dashpattern(on 2 off 6) scaled 3pt;
dp[2] := dashpattern(off 4 on 2 off 2) scaled 3pt;
path p; p := (origin .. (2,1) .. (3,-1) .. (5,0)) scaled 3cm;
draw p dashed dp[1] withcolor blue;
draw p dashed dp[2] withcolor red;
endfig;
end.

Mojca,
thanks so much, this works and does exactly what I want! For the rest
of my questions: I've decided to go for an embedded staticMPfigure
instead of MPpositiongraphic, so I can manage. But I'd still be
curious if these things are possible or not. Anyways, thanks a lot!
