scientific notation for axis labels?

Bill, 

thanks for your previous help. I have it all going now except for one small
detail:

Many of the concentrations are very small (e.g. 1e-6 range), and it appears
to me that the labeling on the axis shows "0" for both low and high values
whenever the high is <0.001.

Is it possible to either switch the labeling to scientific notation when
the maximum is smaller than 0.001 or use scientific notation at all times?


Thanks again,
Hartmut
