Symbolize by Line Thickness (Business Analyst)

Résumé

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

Usage

• 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.

Syntaxe

SymbolizeByLineThickness_ba (InputFeatureLayer, Field, ClassificationSchemeParameterName, ColorParameterName, {NameField}, {UseSelectedFeatures})

Paramètre	Explication	Type de donnée
InputFeatureLayer	The input feature layer.	Feature Layer
Field	The attribute field used to define the thematic map.	Field
ClassificationSchemeParameterName	The classification method to thematically map your input feature class. Natural Breaks —Uses natural breaks classification to produce a thematic map. Std Deviation —Uses standard deviation classification method to a produce a thematic map. Equal Interval —Uses equal interval classification method to produce a thematic map. Quantile —Uses quantile classification method to produce a thematic map.	String
ColorParameterName	The color assigned to the lines to be symbolized.	Long
NameField (Facultatif)	The attribute field used in the normalization calculations.	Field
UseSelectedFeatures true false (Facultatif)	Identifies the features that will be used to generate the thematic map. True —Uses only selected features to generate the thematic map. False —Uses all features to generate the thematic map. This is the default.	Boolean
