If you have an attribute to distinguish between the points consistently from place
to place then this might be doable. For example, if you could attach a sequence
number from 1 to 5 to each place then you could use classes and offsets.
For example:
seq name color
1 place1 red
2 place1 blue
3 place1 red
1 place2 white
1 place3 red
2 place3 blue
then you could have a layer like:
LAYER
...
CLASSITEM 'seq'
CLASS
EXPRESSION '1' # no offset
STYLE
...
END
END
CLASS
EXPRESSION '2' # ul
STYLE
OFFSET -10 -10
...
END
END
CLASS
EXPRESSION '3' # lr
STYLE
OFFSET 10 10
...
END
END
...
END
This would have the effect off ringing the center point with the other data. You could
create other patterns (such as a line) with different offsets.

Dear All
I would like to know, are there any method to show mutilple points with their
own attributes on same xy? Sounds complicated.
Here is my case:
There are many ppl in same xy, each ppl carry 1-5 color ball(s).
I would like to show these five ppl and also what color ball(s) they are carrying
on the map in same time.
Does anyone experiense similiar case?
Is it possible? Since I have seen a disperse function in mapinfo.
Thanks all
Regards
Taka Wong
