The first half of the year certainly seems to be having a promising start. Wonder if the second half is as good?

Bring this data into Query Editor and unpivot it so that it can be presented within report view. Create a line chart based on these results:

Messy unsorted line chart

Yikes! We can't tell anything from this due to the weird month order.

Import the month numbers table from the Excel file in the above folder. Join this to your pivot table via the month names (using the month number to sort the  month names):
