I'm using the HTML5 Time Series Line chart and get an error message when running the report. The report simply shows charges against 4 account numbers for a period of time. The report works with just the dates and charges but fails when I add the account which is just a string. This same SQL works fine on the the Pro Line Chart. The settings for the series are below as well as the stack trace. Any help would be appreciated.
