I am trying to display two sets of data on the same graph using androidplot; however, the data sets have very different scales. Whilst I could do some kind of normalisation of the data sets to make them compatible, I would rather plot them on multiple y axes - e.g.

I can pretty much do this in achartengine, but I think that androidplot produces better looking graphs and provides a "better" (i.e. more android like) architecture.

Does anybody have any ideas: a) if it can be done? and, b) how to do it?

I'm guessing that by now the answer is a little late to be of use, but here it is in any case:

Androidplot does not provide any built-int support for displaying multiple log scales using different tick intervals simultaneously. As you already noted, the most popular workaround is normalisation, which forces you to use a shared tick interval. Having said that, one Androidplot user was able to find a workaround by overlaying data:
