You meant to say Yes. Your numbers are between 0 and 100. I assume this is 0 and
100%, in fact, you say they are cumulative percentages. The Y axis numbers you've
indicated are commonly used in probability plots, but they are not, strictly
speaking, evenly spaced.

Barb suggested this web page:

I suggest you go to this page, and see what a cumulative probability plot looks
like, then decide whether in fact, the way that it shows a cumulative percentage of
a factor plotted on the X axis is what you need.

No. My numbers are all above 1. Basically what I've been asked to do is
visually "squash" the datapoints.

It is kind of like a log-scale, in that we want to show more information in
less space, but it is not a probability plot. The x variable is a log of a
workplace protection factor for certain equipment. The y variable is the
cumulative percent.

I'm using Excel 2002.

I have data that looks like this:
X Y
2.56937391 4.077622647
2.58546073 8.180775241
2.589949601 12.29105172
2.657055853 16.50782651
2.741151599 20.8580621
2.854306042 25.38787495
2.862131379 29.9301067
2.935507266 34.58878672

3.937417581 100

I need to produce a scatter plot in excel. Simple to do in general.
However, the requestor has asked me to have the major y-axis values be


these

(evenly spaced on the y axis):

0.1
1
5
20
50
80
95
99
99.9

I was able, using information found at http://PeltierTech.com/ (thank you
Jon) to make a dummy series that would portray the axis as I needed it.
However, the data is still plotted on the "real" axis and obviously does


not

line up with the "fake" y-axis values. Because there is a different


amount

of "space" between the major ticks, the distance between points will need


to

vary.

Any suggestions appreciated. I am going to try a SAS solution as well,


but

the end-users prefer to be able to do it in excel.
