Hi,

Break the problem down by calculating the area of each triangle in the
radar plot and then summing them.
Assuming your data series for a 3 point radar chart is in A1:A3 put this
formula into B1 and copy down to B3.

B1: =0.5*A1*A2*SIN(DEGREES(360/3))

To make the last points formula work you will need to reference point 1.
The easiest way to do this is to add a formula in A4 which references A1
A4: =A1

To find the area sum B1:B3

Cheers
Andy
