Hello Hans,

It would be great if the ConTeXt chartflow module would make it
possible to use a + or - in the \location macro.

So instead of:

        \location{2,1}

You could say:

        \location{+,}

This should be interpreted as:

        +: increment x or y position
        -: decrement x or y position
        empty: no change in x or y

The current x or y position are the last x or y used (or calculated)
with a \location macro.

Groetjes,

Berend. (-:
