Make the line chart with the first set of data, and set the X axis to use
days as the base unit. Add the second set of data, which produces a second
line series using the X values for the first series. Convert just this
series to an XY type, which breaks its dependence on the first set of X
values. Then, in Excel 2003 or earlier, you can move the XY series back to
the primary axis, and it will be aligned appropriately. In 2007 you have to
keep the XY on the secondary axis, and align all the scales yourself.

I'm trying to do a comparision line graph with two series of data. The
are
both tracked by date with the same range (from April 2008 to April 2009).
However one series has data monthly and the other has data weekly. When I
try to combine on a graph the dates just don't line up.

Is it possible to have these line up correctly. I've tried formatting the
axis to days instead of months but it appears to only line up data points.
So for the data reported monthly, it is graphed across the first 12 days.

Hopefully that makes sense. If not, just let me know & I'll try to
clarify.

Thanks!
