I received a spreadsheet with a pie type progress chart contained within the cell. It is divided into quarters. Put 3 in the cell and 25% of the pie is shaded. put in 9 and 75% is shaded. 12 and 100% and so on. What is this and how do I chnage it to read more than just quarter segments? Can I chnage to 1/12th segments. How can I show you what I am talking about?
