Icon Sets debuted in Excel 2007
In Excel 2010, they added a set with Up, Flat, Down
But an icon set can only look at one cell! How can you use it to compare two cells?
Copy two helper columns off to the side
Use a calculation to show the change
Type that formula without using the mouse or arrow keys to prevent =GETPIVOTDATA
Use the SIGN function to convert that to +1, 0, -1
Add the Three Triangles icon set to the helper cells
Why do they call it Three Triangles, when it is really 2 triangles and a dash?
Manage Rules, Edit the Rule. Show Icon Only.
Manage Rules, Edit the Rule. Change from percent to numbers
Use greater than 0 for Green up arrow
Use greater than or =0 for yellow dash
all of the negative numbers will get the red down...
