Need help with showing Totals

[Bob]

I have a clustered cylinder chart. Along the x-axis, I have the average test
score per exam per class. For example, in the first cluster I have the
average test score for five exams in the Science class. In the second
cluster, I have the average test score for five exams in the Mathematics
class, etc.

For each average test score, I would like to display the total number of
students that took the test above each score.

In looking through several of the previous answers in this discussion group,
I think I need to add a dummy series and plot the total number of students
against a second y-axis, but I am not sure.

Can someone please show me how this can be done? I am using Excel 2007.

I would greatly appreciate any help.

Thanks,
Bob

Luckily for you it is not possible to plot a second axis when you are
using a 3D chart.

i say lucky, because to achieve your goals you need to flatten your
chart to a clustered column, which is a much better way of displaying
your data.
Having done that, you can simply plot your additional dummy series, add
data labels with the values then select it, go to format it and choose
"plot on secondary axis". Format the new series to be invisible (eg for
a line chart have no lines and no markers, for a column have no border
and no fill). Now delete the new axis so that it is sharing a scale with
the first axis again, so the labels will appear in the correct positions
near your data.
Job done.

Hope this helps
