This was asked a few years ago in this thread : How to make a Line Chart curved instead of straight from point-to-point?
The SWF example was posted but not the .XLF and it does everything that I would like but again the thread was old. Does anyone have the related .XLF or know how to calculate the values between 2 numbers to get the nice curve look ?
Its quite important to complete the look of a dashboard I am working on.
Thanks in advance
