I am plotting records (name, address, salesytd, etc.) in MapPoint North America 2010. My data set is being mapped by Longitude & Latitude based on Salesytd with 5 Equal data points (quantiles). My lowest range is from -1,492 to 117 which is mapped with a blue circle. I have a customer in the data set with a salesytd of 0 that shows as being mapped but there is no blue circle for them. I can search for them by name but again there is no way of telling where they are on the map except for doing this. This makes me wonder how many other records are like this. Any advice would be greatly appreciated.
