Command line syntax

ET_GPSpiderDiagram <centers_dataset> <Destination_dataset> <out_feature class> <Cutoff_distance> {output_spatial_reference}


Expression Explanation
<centers_dataset> A Point feature class or feature layer
<Destination_dataset> A Point, Polyline or Polygon feature class or feature layer.
<out_feature class> A String - the full name of the output feature class (A feature class with the same full name should not exist)
<Cutoff_distance> A Double representing  the Search tolerance (in the units of the {output_spatial_reference} to be used
{output_spatial_reference} The spatial reference in which the calculations will be performed. If not specified the spatial reference of the input dataset will be used.
NOTE: The spatial references of the <centers_dataset>, <Destination_dataset> and {output_spatial_reference} must have the same Geographic Coordinate System

Scripting syntax
