Superimposing two flowcharts

Superimposing two flowcharts

[Sytse Knypstra]

Hi all,

I would like to make a flowchart in which one shape (FLOWcell) is 
essentially bigger than the other shapes (in fact it should occupy the 
space for two ordinary shapes).
Now I made two flowcharts; one consists of the one bigger shape, while the 
other consists of the remaining shapes (of which two are invisible because 
their shape is defined as `node'). My idea is to put one flowchart on top 
of the other.
Is this possible? And if it is, how should I do this?
B.t.w. using `offset=overlay' in \setupFLOWcharts gives a syntax error.

Thank you Hans.
The remaining problem is that the bigger shape is scaled down to the size 
of the smaller shapes.

Hi Sytse,

I see, you need a shape that spans n cells. I must figure out a way to 
extend the flow charter with that (i.e. a kind of virtual shape, where the 
lines are still drawn from separate nodes, something:

\startFLOWspan
  \name{Obs}
  \location{1,1}
  \shape{action}
  \text{{\bf observations}}
\stopFLOWspan

so let's put that on the todo list ... (remind me in a while, i need to 
print the modules and look into it)

For the moment, you can do something:

\startFLOWchart[Observations]  % The bigger shape

\setupFLOWcharts
   [nx=3,
    ny=2,
    dx=40pt,
    dy=25pt,
    breedte=260pt,
    hoogte=130pt]

\startFLOWcell
  \name{Obs}
  \location{1,1}
  \shape{action}
  \text{{\bf observations}}
\stopFLOWcell

\stopFLOWchart

\startFLOWchart[Parameters] % The smaller shapes

\setupFLOWcharts
   [nx=5,
    ny=2,
    dx=40pt,
    dy=25pt,
    breedte=110pt,
    hoogte=130pt]

... you need to fix the widths and distances (some kind of larger grid) but 
since calculations is part of your profession i leave that to you -)

(you can use \dimexpr for that)
