Ah...just found small bug: can drop data *set* onto config dialog
thingies - causing a crash with:

libguppidata-ERROR **: file guppi-seq.c: line 255 (guppi_seq_size):
assertion failed: (max+1 >= min)
aborting...

Not sure I understand what you mean...

I suppose you could get what I was thinking of by having multiple
overlaid scatter plots on the same graph, each having separate data
input dialogs in the config box. Based on some previous conversation we
had, I think that perhaps you'd need one input dialog per *style* -
currently you can't use the alternative styles anyhow ? I thought the
original idea was to be able to select/filter/copy data elements into
another style - would this be a separate scatter plot or separate
data-sets/styles on the same scatter plot...?

Nice :)

Good ;)

Ahem yes ;) I'm just brainstorming and comparing to other plotting
tool(s) I use...

OK ta :)

BTW, the scatter plot axes are slightly removed from the plot? That is,
they don't join at the edges?

S'ok :D
'tis getting there ;)
