Hello all,

After studying the CHARTS manual I am glad to be able to construct some
simple charts. The example below is working ok.
Still there are some puzzles left:

1. How do you construct different types of connection (dashed, without
arrows, all in one chart (like in Figure 19, p.11 of the manual)? I know
that you can change the line styles for all lines that follow by
\setupFLOWlines, but what if some have to be with arrows, and others without
arrows and/or dashed? BTW, I use the dutch version of ConTeXt.

2.  I would like to try the \help command as described on p.16 of the
manual.
Where do you define the helptext and what command do you have to use in the
dutch version? Could someone add the necessary lines to the example below?

3. What is the function of maxwidth=... in \setupFLOWcharts. Changing its
value in the example below doesn't seem to have any effect. Is it possible
to scale the whole chart to e.g. half its original size?

4. In the manual the meaning of x and y in \setupFLOWcharts is not
explained.
Could someone explain them to me?

Thanks,

Sytse Knypstra
