Here's the demo file I used last night at the BTUG to demonstrate right drag, multiple levels of detail, and jitter. If you have any questions or suggestions, please reply to this thread so everyone benefits.
Many thanks to Kathy Wilder and all of the Grand Circle staff for hosting and headlining last night's packed event. The level of Tableau Server implementation and integration achieved by the Grand Circle team in just one year is remarkable.
Next event will probably be the Tableau 8 roadshow, stay tuned to this forum for dates and details.
