Additional Information
This behavior is expected for a one-to-many join. In this particular case, each elevation value for Montana is drawn as an individual polygon, and each of those polygons are drawn on top of each other (10 in total, equal to the number of records for Montana) in a randomized order. The elevation value of the polygon that is drawn on top of the stack is the value that is used to place the polygon in a class. In cases like this one, the user has two options to display the mean elevation value using graduated colors: 1. Using the Summary Statistics geoprocessing tool to create a table with mean elevation values for each state, and then apply the join.
