[m-chart] Connections

[m-chart] Connections

[Marco]

Hi,

I cannot  figure out  how to connect  to the  bottom right
point  (the small  red  one). Anyway,  in  the manual  the
shortcuts to address the  individual points are not really
explained. I blindly guess:

tm - top middle
t  - top middle
bl - bottom left
br - bottom right
bm - bottom centre
b  - bottom centre
…

However,  in the  following example  it doesn't  work. Any
ideas?

%%%%%%%%%%%%%
\usemodule [chart]
\setupFLOWcharts [option=test]

\startFLOWchart [mychart]
	\startFLOWcell
		\name     {foo}
		\location {1,1}
		\shape    {action}
		\text     {Foo}
	\stopFLOWcell

	\startFLOWcell
		\name     {bar}
		\location {1,2}
		\shape    {action}
		\text     {Bar}
		%\connection [tmbl] {foo}  % left
		\connection [tmbr] {foo}  % also left ??
	\stopFLOWcell
\stopFLOWchart

\starttext
	\FLOWchart [mychart]
\stoptext
%%%%%%%%%%%%%

Regards

Marco Patzer

These don't look right. I haven't checked what the manual says, but I 
usually use

t, t+, t-
b, b+, b-
r, r+, r-
l, l+, l-

t b r and l correspond to top, bottom, right, and left. The other two 
points are accessed throught t+ and t- etc. IIRC, for top and bottom, + 
corresponds to the right point and - to the left point; for left and 
right, + corresponds to the top point and - to the bottom point.

According  to  this, [tb+]  should  yield  to the  desired
result. However, it produces the same output as [tb].

The order of arguments is now different in MkIV (bug?),
you have to write “tmb” or “t-p” to connect from the center
of the bottom shape the left of the top shape, the two
keywords “m” and “p” are synonyms for “-” (minus) and “+” (plus).

It is more likely that I did not recall the syntax correctly.

Neither do I, I don’t use module often enough to remember syntax.

To be sure I looked for the correct input and also MkII expects
the + and - before the location of the node but MkII had “n” as
synonym for + which is now “m” in MkIV.

I see.  Thanks for  checking the  sources. That  means the
syntax is as follows:

       -t    t    +t
     ---------------- 
 +l |                | +r
    |                |
  l |                |  r
    |                |
 -l |                | -r
    |                |
     ---------------- 
       -b    b    +b

I added a section to the wiki.
