I came up with a way to simulate the effect for one data set before
realizing that...
Actually, no, it doesn't make any sense for multiple data sets, at
least not to me. How do you envision the spacing along the x-axis for
the following?
Data set 1 partial x-values: 96, 97, 100, 98, 95.
Data set 2 partial x values: 95, 98, 100, 101, 105, 103, 102, 101, 94.
Here's a simple solution for one data set. As long as the data have
only one maximum, just subtract Max(X-values) from all the actual x-
values! Use these new values as the x-axis values. Also create a new
column of data with all zeros. Plot this as a new series. Remove the
displayed x-values (double-click the axis, select the Patterns tab, set
'Tick mark labels' to None). For the new dummy series add the
*original* x-values as data labels (use XY Chartlabeler from
www.appspro.com
or Chart Tools from
www.j-walk.com
).

I had thought about merging the data, but unfortunately it's not quite as
straight forward as 10,20,30,20,10 merging with 15,25,35,25,15 etc. Each set
is 200 points, and for example, one has a range of 60 to 100 to 60 and
another is 65 to 100 to 65. The x-values can be any value within those
ranges, and are not integer values. Also, I would still have to plot as a
line chart to get the increase/decrease x-values, and it wouldn't work as i
want it to beacause each value would be a category and the actual x-values
for each data set would not align, if you see what I mean.
I suppose I could create a formula to merge the two sets to one x-value
range, but when I first thought about it I didn't try becasue it would take
me too long to get it right! My VBA isn't really up to the challenge
either....
If thats the only way to do it, I'll have to try and fudge something
together. But if anybody knows a way to get increasing/decreasing values (eg.
60 to 100 to 60) on the x-axis of a scatter graph, it'd make things a whole
lot simpler...

What you have to do is 'merge' the x-values of the 2 data sets. In the
example below the x-values go from 10 to 40 to 10 in DataSet 1 and from
15 to 45 to 15 in DataSet2. I reorganized the data so that the 2 sets
'interleave.'
Data set 1:
10 1.061231423
20 1.861363713
30 6.561589331
40 3.4964915
40 9.683049858
30 20.00872277
20 11.95088416
10 11.62636711
Data set 2:
15 3.4709576
25 2.725999451
35 16.9991303
45 18.1101212
35 21.63843686
25 12.27002799
15 35.20802415
Merged data set:
10 1.061231423
15 3.4709576
20 1.861363713
25 2.725999451
30 6.561589331
35 16.9991303

15 35.20802415

Plot the merged data set and it will give you exactly what you want.
It isn't pretty to set up but if you have a lot of data (whether 200 is
a lot is up to you) and are comfortable with VBA you may want to
automate the process.

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.
