Ah, that'll be why it's 100 separate series.

If you go back to the original data, with X values in B2:B101, Y values in
C2:C101, put a label (Y, or whatever) in C1, & leave B1 blank.
Select B1:C101, Insert/ Chart/ XY (& choose appropriate sub-type)/ Data in
columns/ other options to suit.
When you've got your chart you can put an X label in B2 if you want.

The original data set was 100 rows of data with the headers in the first
column, X values in the next column and Y values in the next. I couldn't
figure out how to make it work without transposing the X values so that
they
appeared in the first row and there was a Y value only under the relevant
X
value, so the data set ended up being 101 rows by 101 columns.

It sounds as if you've got 100 different series, rather than one series
with
100 points which is what you want. What is the layout of the data in
your
worksheet, and how did you produce the chart?

I have an XY Scatter Chart with 100 entries. The data points plotted
fine,
but the graph automatically assigned a different symbol and color to
each
data point. To make the chart look cleaner, I wanted to make all of
them
the
same. I can select and change the data points individually, but it
would
take a while. Is there any way to change them all at once?

Thanks,
