Graduated Symbol Theme SOAP Request

This is an example of a SOAP mapping service request for a map containing a graduated symbol theme where a reference scale of 10,000,000 has been set using SymbolBaseSize. For a demo of the request, go to the Mapping Service Demo Page for your local installation at http://<server>:<port>/Spatial/MappingService/DemoPage.html .Notice the size of the graduated symbols. If you change the ZoomLevel from 3000 to 1500, and re-submit the request, the resulting graduated symbols will appear about twice as large as the original request.
