ArcMap

Symbolize by Line Thickness

Доступно с лицензией Business Analyst.

Краткая информация

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

Использование

  • You can display lines at different thicknesses to represent different values.

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

  • You can use this tool to display road segments with different thicknesses based on traffic volume during rush hour.

  • This tool can be used in conjunction with the Desire Lines tool. Desire lines can be displayed by total sales or number of visits for each customer.
