Hi all,
Just switched from S&T to MP 2006. I am using the US Demographic data in Data Mapping and have picked the areas I need and exported to excel to get just the territory, and then imported that data to a clean map. (Is there an easier way to do this?)

What I then am trying to do is plot the population over time. What I would love to do is take the 1990 population by zipcode as the shaded area, and then show the next period (2000) population and color it a different color. Is there an easy way to flip back and forth by hiding one of the data sets? I seem to remember in S&T you could hide a dataset fairly easy by clicking on the legend bar.
Any advice is appreciated.
