    Nulls in Bar Chart

      I have a bar chart that depicts patient puntualtiy.  I want to be able to show the % of patients that are early, on time, and late.  The logic is quite simple,


      Appointment DateTime - Arrived DateTime


      (See attachment for sample chart)



      My issue is that there are null values in the Arrived DateTime column which is giving me a forth value in the chart.


      Can anyone think of a way to disregard the nulls and only look at the Arrived DateTime when it is populated? (Nulls mean the Patient Cancled or No Showed)
