Hi all,
I am relatively new to Excel. I am trying to plot the function y=0.000643688x³-0.065413x²+1.88017x-9.17115. This is a line I want to have in my chart. Additionally I want to be able to enter onto the same chart a set of data values. (I am interested in visualising the position of these points compared to line - are they above or below line? ). How can I go about doing this?

I hope what I've said makes sense.

Many thanks in advance!
