How do I get the x-axis to be a range of "values" instead of "categories"?
I am trying to do a line chart with values over a % range, but I do not have
values evenly spaced over the entire range (The chart is asymptotic and I
only need to see values from 0 to 40 or so) e.g.:
X Y
0.5% 28.8%
1% 44.8%
2% 62.2%
5% 80.9%
10% 89.9%
15% 93.4%
20% 95.3%
35% 97.7%

I get the X axis evenly spaced in 8 categories. Seems like older versions
of Excel (I am using Office XP/2002) allowed me to set the range and
divisions within the range. How do I handle this now?

Thanks for your help.
