MapPoint 2002 Is it possible to add multiple sets of data to the same map? I would like to show vendor locations with one color of pushpins and customer sales in another color of pushpins on the same map. The Chart style map is too busy for the data I'm trying to display.

Yes, you can have an unlimited number of data sets on the map at any time. By the way, if your vendor and customer locations are in the same file, you can use the "multiple symbol" chart type to bring them in at the same time, with a different icon for vendors and customers (assuming there is a column in your data that distiguishes the two).
