As far as I know the FLOWchart module you can include existing pieces of charts into a new one (see also the manual). However I would not know how to separate the shapes from the arrows and combine the parts at will.

Hi all,

I have definitely not been flooded by answers. I am getting the impression that this forum might not have been the best one to ask (i.e. I have a practical problem which has little bearing with implementation aspects / bugs / new features of Context).

I have gone through comp.text.tex, but it seems to be heavily oriented towards latex. Would you have any other direction I could go to and get some assistance?

Thanks for showing a door (;-)),

Emmanuel

Thanks Hans. Apologies if the discussion doesn't flow very much, I am writing from down under.

In fact, what I would ideally like to do is the following:

1- Define a template with the boxes without any arrows. 2- Write numbered lists describing arrows that would be generated on top

of

the template.

The overview might look like the following (with some bogus macro names):

% Somewhere in a template file % Template for the boxes:

\StartMPTemplate[Boxes] % % ----- ----- ----- % ! ! ! ! ! ! % ! A ! ! B ! ! C ! % ----- ----- ----- % \startFLOWcell \name {a} \location {1,1} \shape {action} \text {\ss A} \stopFLOWcell

\startFLOWcell \name {b} \location {2,1} \shape {action} \text {\ss B} \stopFLOWcell

\startFLOWcell \name {c} \location {3,1} \shape {action} \text {\ss C} \stopFLOWcell

\StopMPTemplate

------------------------------------------------------------------

% This creates the first chapter \startcomponent Right \Chapter{Every to the right}

% Inserts a float with the proper figure and the proper arrows using the difinitions coming afterward \StartMPGraphWithTemplate[Right] \IncludeFLOWchartTemplate[Boxes] \StopMPGraphWithTemplate

% Place the float \placefigure [here,force] [fig:chart1] {Chart One} {\framed{\FLOWchart[Right]}}

% normal itemised text that will be numbered and will dynamically add tyhe arrows to the figure [Right] \startitemizeWithFLOWchart \arrow[labels=number,from=a,fromside=r,to=b,toside=l] This is the first arrow. \arrow[labels=number,from=b,fromside=r,to=c,toside=l] This is the second arrow. \stopitemizeWithFLOWchart

% This is the result % % ----- ----- ----- % ! ! 1 ! ! 2 ! ! % ! A !---->! B !---->! C ! % ! ! ! ! ! ! % ----- ----- ----- %

% The text should appear below the float as \startitemize would have done

% 1 This is the first arrow. % 2 This is the second arrow.

------------------------------------------------------------------

% This creates the next chapter \startcomponent Left \Chapter{Every to the left}

% Inserts a float with the proper figure and the proper arrows using the difinitions coming afterward \StartMPGraphWithTemplate[Left] \IncludeFLOWchartTemplate[Boxes] \StopMPGraphWithTemplate

% normal itemised text that will be numbered and will dynamically add tyhe arrows to the figure [Right] \startitemizeWithFLOWchart \arrow[labels=number,from=c,fromside=r,to=a,toside=l] This is the top arrow. \stopitemizeWithFLOWchart

% This is the result % !------------------------------ % ! ----- ----- ----- ! % ! ! ! ! ! ! ! ! % -->! A ! ! B ! ! C !--! % ! ! ! ! ! ! % ----- ----- ----- % %

The idea is that everything is dynamic: - if the template changes, all the graphs get redrawn with the boxes at their new place. The arrows get moved as needed. - if the itemised text is changed (say the 'second arrow' line is written before the 'first arrow'), then on the graph, the arrow from a to b would be numbered 2 and the arrow from b to c would become 1.

What I tried is the definition you see at the top for the boxes. Then, to generate the first graph, I would have:

--------------------------------------------------- \startFLOWchart[chart]

% Inserts template \includeFLOWchart[template][x=1,y=1]

% Additional information on top of cell a \startFLOWcell \name {a} \connection [rl] {b} \comment [t] {\ss 1} \stopFLOWcell

% Additional information on top of cell b \startFLOWcell \name {b} \connection [rl] {c} \comment [t] {\ss 2} \stopFLOWcell

\stopFLOWchart ---------------------------------------------------

All I get is the template without any arrows.

I thought about trying to generate massive metafun macros. But I want the itemised text to be text and not a graph.

Bottom line: is it possible? realistic?

I have been using MS Word so far to do that sort of thing. It has been quite tedious to reflect any change in the box structure: 10 charts means 10 charts to re-edit.

As a bonus question that should be easier. Is it possible to draw other sorts of arrows: i would like to draw straght line arrows that could follow a diagonal (say go north-east instead of east first then north), or circular arrows like:

% % ----- % ! ! % ! !<-- % ----- \ % \ % | % ----- / % ! ! / % ! A !<-- % -----

As usual any help is welcome.

Emmanuel

As you might have guessed, this breaks everything.

Has anybody an idea as to how I could do that?

can you make a minimal example?
