Summary
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.
Syntax

Field | The attribute field used to define the thematic map. | Field |
ClassificationSchemeParameterName | The classification method to thematically map your input feature class.
| String |
ColorParameterName | The color assigned to the lines to be symbolized. | Long |
NameField (Optional) | The attribute field used in the normalization calculations. | Field |
UseSelectedFeatures true false (Optional) | Identifies the features that will be used to generate the thematic map.
