ArcMap

Symbolize by Point Size

Доступно с лицензией Business Analyst.

Краткая информация

Thematically maps a feature class based on a numeric field and displays it as a symbolized point.

Использование

  • You can display points using a symbol that varies in size to represent different values.

  • Graduated symbols work best for counts and amounts, since most people associate the size of the symbol with magnitude.

  • An example for using a graduated symbol is to display store points as different sizes according to their sales volume or to show customers according to total purchases or visits.
