I'm trying to plot a line/column chart in Excel with 2 data series.
However when I am trying to add in horizontal gridlines, Excel scales
the secondary Y-axis to integers therefore not matching the primary
axis. (ie. the numbers on the secondary Y-axis do not line up with the
gridlines).

Is there anyway that I can fix the scale so that the numbers will
appear beside the gridlines?

Thanks a lot,
Steven
