Rotation renderer

Purpose

This sample demonstrates how to turn marker symbols into arrows where the size represents velocity and the arrow is rotated to reflect a wind direction.
 
A ProportionalSymbolRenderer is used with additional settings in the IRotationRenderer interface to display arrow markers showing wind direction and velocity. The wind.shp shapefile is used, and it must be the first layer in the focus map. The following fields are used from the shapefile:

Velocity—Specifies the size of the arrow marker
Direction—Specifies the rotation in degrees of the arrow marker

How to use

See How to use ArcGIS samples for help running the sample.

1. Run the sample application. Marker symbols are turned into arrows where the size represents velocity and the arrow is rotated to reflect a wind direction.
