    Is there a way to have the average line extend past the center of the first and last bars? i.e. how can i make the average line extend to all the way to the horizontal bounds of the graph?

      This should help as long as you don't need to use the secondary axis for a different series. Still searching for the answer for when you do.

    Steps 1-3 don't work. The formula is carried through the rows and it calculates an average for the data for each row.

      Did you check that you had locked the reference (look for the $ infront of the Cell references)
