ArcMap

Symbolize by Non-numeric Field

获得 Business Analyst 许可后可用。

摘要

Thematically maps a feature class based on a nonnumeric field.

用法

  • This tool generates a map designed to convey information about a single topic or theme, such as population density.

  • Nonnumeric fields are used only when generating the thematic map. These values will be represented on the map as unique values based on the field used to symbolize.

  • Nonnumeric thematic maps cannot be normalized, since they contain no numeric data.

SymbolizebyNonnumericField_ba (InputFeatureLayer, Field, {UseSelectedFeatures}, {ColorSchemeParameterName})
