Hello--

I attempted to plot a trendline as a new data set (I looked at the fit equation and created a new set of data with it). However, the line the equation draws is not the same as the trendline! Am I making a mistake somewhere?

The black line is the trendline. The blue line is the line the equation describes.

Thanks,
Jennifer

For the Y column I'm using:
=(0.0000000009*(J2^3)) - (0.000004*(J2^2)) + (0.0057*J2) + 0.3246

Col J Col K
X Y
20 0.4370072
30 0.4920243
40 0.5462576
50 0.5997125
60 0.6523944
70 0.7043087
80 0.7554608
90 0.8058561

120 0.9525552

...and so on...
