have you tried a symbol inside a symbol. I manage to use the same datapoint
more than one thematic mapping different columns, loading the layers as many
times (more than 3 get dificult to interpret) assigning different symbols at
each layer. To the one on the bottom i assign a bigger symbols and as i go
up on the layer position i use a smaller symbol
could work

Asunto: MI Bivariate thematic mapping
>Has anyone done bivariate thematic mapping in MapInfo using two different
variables succesfully?
>
>I would like to be able to map a dengue fever outbreak and fill property
polygons (regions) with a foreground colour for each mosquito species
detected and then change the fill of the same polygons so it varies
according to the number of breeding sites on the premise.
>
>I have successfully managed each operation separately but am having
difficulty organising the thematic mapping so that both variables are
displayed.
>
>I already have symbols on the map polygons to indicate other variables so
that why I would like to use the polygon fill to state on of the variables.
>
>Please tell me there is an answer to this! -Maybe an .mbx that takes
thematic mapping a little further? aaaagggghh......
