Default Is there a way to obtain a polynomial trendline of order higher th

Hi,

I have data which generates an s-shaped curve. The best trendlines that can
be obtained in Excel are of the order 6 and that isn't close to the accuracy
I am seeking.

Does anyone know if there is a way in Excel to get a trend line of order
higher than 6?

Thanks in advance,
Vikram
