SO I'm trying to put 2 different series on the same graph with different
chart types. One series as a line plot and one as a scatter XY. I put the
first series in a line chart because it's lets me use equally spaced dates on
the x-axis, and then the second series is in scatter plot.

This has worked fine up til now: For some reason, Excel wants to plot the
data from the second series far in the future (the year 4300), while the
first series plots fine. (all data is in dates between 1977 and 2003).
There are no mistypings, and I even played with the cell formats to see if
there was something hidden, but no luck. Any ideas?

A clue?: At first it tried to include a lattitude value I had mistakenly
included (it was treated as a serial, which equaled the year 5000 or
something), but even now that I've deleted that row and pasted the correct
information in a new sheet, I'm getting the same error.

Thanks.

PS - here is my data:
