You can choose from graduated pies or half pies. Graduated pies graduate the size of the pies according
to the sum of their components. Half pies distribute your data across half a pie instead.

Graduated Symbol Maps
Graduated symbol maps use symbols to represent different values. You can use graduated symbols
regardless of the type of map object with which you are working.
For instance, use graduated symbols to show the number of housing units by city. When you select the
graduated symbols option, MapInfo Professional varies the size of each symbol according to the value
in the sales order field.
You can also represent how much interest each customer has expressed in a given product by assigning
a symbol whose size is proportional to the customer's interest.
Graduated symbols maps work best when you use numeric data. If you are working with a layer of
restaurants, it makes no sense to create graduated symbols based on the type of cuisine each restaurant
serves. However, graduated symbols are appropriate when you want to show the relative number of
housing units by city as in the next figure.
