Sum issues by certain measure

This was a timely discussion for me. I was able to use this discussion to get a similar property count in my own environment. What we really wanted was a graph of the daily count of issues containing each of the respective values of this property. I’ve had to create individual custom measures for each value of the jira select field in order to be able to graph these counts. Is this the recommended approach to count the unique values of a property over time or is there a simpler way to graph that there were x issues with property b and y issues with property c on day z?
