I have been doing some analysis of reaction kinetics.  The
best way to plot the data is a rate versus inverse
temperature.  My issue is that 1/T is not a number that
people that recieve my reports generally use, but
temperature is.  I'd like to label the x-axis with values
for temperature.

1) Is there a way to plot X vs. Y and label an axis with Z
instead of X?

Alternatively,
2) Is there a way create a custom scale?  I don't
generally plot log(X).  I usually just change the axis to
log scale.  Can I create a 1/X scale?

Thanks!
