You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
One of your colleagues has created an excellent pivot table within Excel. While it may look excellent there, however, it causes problems within the data model:
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:
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):
A very handy feature which makes our months appear in a more logical order.
Recreate the line chart using the sorted month column from the other table, admire your sorted months:
Ouch. Guess the summer holidays didn't help with focussing the mind!
Optionally save this as More grades, more green and then close it down.
