Tim Shields,
Thank you for your kind reply. But the problem is that my data is
chbarecter fied, A,B,C not numeric...but charecter.
Yes I have a combination of three in an expression as
81+"/"+82+"/"+83.. that would return the combinations of theose in to colors..
ie A+A+A is red
A+B+C is yellow so on..
But, I want to represent the vaules in the same polygon, by
breaking the polygon or using any other possibility...
Do, you have further suggestions????

Hello Harsha,
If you substitute numeric values for A,B,C so that A=1, B=5, and C=20
you
can calculate a sum of these three values. A result of 3 would
indicate A
for three years, a value of 11 would indicate B for two years and A for
one,
a value of 26 would indicate A, B, and C for one year each, etc. Your
results could be categorized into discrete outcomes which you could
then map
thematically.
Hope this addresses your situation.
Good luck,
Timothy M. Shields

Subject: MI-L Thematic map query expression....
> Hello listers,
> I have a doubt of how to represent my data in a
theme.
The doubt is I have A TABLE like this for a map. The table contains
Year
field (its is like 1981..etc I shortened), and P represents the data of
people.
> The data is for the presence of a particular person at the same
location (polygon or house). i.e In 1981 in a ploygon B is occupying
and in
82 A was occupying and in 83 A was occupying.
> Now I want to create a Thematic Map, such that I can
represent
in the same theme such that I can represent the presence of A,B,C..etc
in
the same polygon for three different years. I tried myself generating
themes
by expresion.. Pls help me.. how can I give the expression

> Y 81 82 83
> P B A A
> P B A B
> P B B B
> P B B B
