dual y-axis plotting - is it possible in mathematica?

I'm trying to figure out how to create a dual y-axis scatterplot, but there doesn't seem to be any documentation about how to do this in Mathematica's help or anywhere online that comes up in a search engine quickly.

Anyone here know how to do it?

By dual y-axis plot, I mean a plot which has one y-axis on the left and one on the right, with different scales, but with a common x-axis. I need to be able to make such a plot because I would like to illustrate the measurement error of a plot of measured values, where the error is much smaller than the measured values. Because the data is this way, it's difficult to see variation in the error unless you have a second y-axis that's on a much smaller scale (say 0 to 0.1) vs. a scale of 0 to 50 for the measurement data.

There does seem to be plenty of documentation about how to do this in other systems, and I already know how to do it in Excel. I'm rather surprised there isn't an easily accessible way to do it in Mathematica... so, any ideas?
