No. It was purely a programming error on my part. I typically work in
normalized coordinates and I was setting YCOORD_CONV in my code, but
when I did the work for creating a log axis and plot, I forgot to reset
YCOORD_CONV to match the new data range. So, I was plotting the data
and the axis against the first data range (before the log was taken).

Is this something to do with the axis range (e.g. !Y.CRANGE) being specified in powers of
10 rather than regular old absolute units?

Well, it seems that I have figured out my immediate problem. I finally
have a log plot working! Turns out that the real problem was what I was
giving to YCOORD_CONV. *sigh*
