Can you make sure that on your slope line test, that the month number is the number from the start. i.e if you start your graph in July 2016, the first point should be 1, not necessarily based off of the month’s number (i.e July is the 7th month).
Secondly did you apply the slope to the y-axis graph?
I filtered the graph to start at beginning MonthNumberOfYear to start at 1, and increment by 1 naturally with filters, which should allow us to move forward with the functionality testing piece.
I can look to make this more dynamic later, with possibly a Rank function or something.
By Default, the Y-Axis on my line chart is based on the ‘Values’ I drag/drop into the field well, so I applied both of the Test measures and neither one is yielding a non-blank value for me in this context.
