Why don't you create a "helper" column of data to get the X axis values that
you want. I'm not clear on how you want to display your data though, so
this may not be what you need.

I have many sets of data for which the x-values run up from approx 60 to
100,
and back down to 60ish. Each set of data consists of 200 points. I can
happily display each set individually on a scatter chart, with the
categories
from, 60 (at point i=1)to 100 (i=100) to 60 (i=200). My probably occurs
when
I want to display two sets of data on the same graph. For each set, the
x-values vary, for example another set could run from 65 to 95 then back
to
65, but it still contains 200 points. Excel will only allow one set of
values
on the category axis, so only one data set will be correctly represented
by
the x-values. Using a scatter graph uses numerical x-values rather than
categories, so my x-values only go from 60ish to 100ish, which is not what
i
want.

Is there any way to use numerical values on a line chart, and have each
data
set represented correctly against the x-axis? Or similary can I create a
scatter graph with x-values running from 60 to 100 to 60?

Any help greatly appreciated.
