Crystal Report Experts : Can we create one graphic from multiple fields

Dear Experts,

Can we create one graphic from multiple fields ? Because I think
Crystal Report has limitation that it can only display one field for
one graphic (within a range of data)

Suppose we want to display graphic of fields : Customers Count, and
Customers Spend in a range of data, how will we do it ? I wonder what
the legend in the report use for.

Help me on this ok ?

Sincerely,

Eddie Jones, Indonesia.
