Unless someone has come up with a cool trick, the functionality in th
chart tool doesn't seem to allow it.
But, I know how to get around that. What you can do is create an
"drawing" item that allows text inside it (like a rectangle, square
oval, or text box) and you can link it to a cell. Then that cell ca
contain the formula that you want.
Here is how you do it, create one of the drawing items I mentione
above and select it. Then click in the formula bar and enter "=" and th
cell address that you want to reference (like A5) and press enter. The
in the cell that you referenced you can create any formula that you ca
think of and the drawing object will display that value, number, text o
whatever.
Next you can size and format the drawing item over your chart where yo
want it and it will dynamically update based on changes to the dat
based on the formula that you created.
Give it a try,
