3. procure y-values at a particular time point x on the trendline that is plotted through the averaged points
4. display an equation for the trendline?
If possible, I would prefer an interactive explanation. Is it possible to do all this using only the GUI? I have tried to graph different series using the Graph Builder tool, but I just get each replicate graph stacked. On the Fit X by Y, I am confused as to how to graph multiple series at once. I am unsure of how to get graphical output, or how to predict a value, from the New Column Formula method as well.
