Hi all,

I'm messing around with the trend line function in excel. I see there
are 6 different types of trend/regression types:

- Linear
- Logarithmic
- Polynomial
- Power
- Exponential
- Moving Average


I have a list with 30 data points that I would like to plot on chart
with the different trend/regression lines. I notice that the Power and
Exponential options are greyed out, so that I can not choose them. Is
this because 2 of the 30 numbers are negative?

Thanks!
