How to symbolize polygons in time-enabled maps

Discussion created by IYTE-ARCHITECTURE on May 30, 2011

My apologies for cross-posting, I have a quick question which I've been trying to find a working solution for weeks. I'm trying to investigate the spatial distribution of cancer data within a province for year 1995, 2000 and 2005. I have exact locations of each cancer patient (without any personal private information) in districts as a point feature class for each year. When I enable the time in
point layer, I can easily see the the change between years just using the slider. But  what I'm trying to do is that to change the symbol of districts (polygons) instead of points. The sample screen-shot is attached.

Of course each polygon could only be  spatially joined to one point. I believe  the solution  could also applies to Tracking Analyst Extension. Thank you for sharing your experience and  suggestions in advance.

Kind Regards
