Exactly. I want to plot the original data once, but the two y axes show
different scales (units). Is twinx() good for that? How?
Thanks.

I wouldn't call it "good", but you can make it work. Basically, you'd plot
your data once in F, then convert it
I hope the code below gives you some idea.
def Tc(Tf): return (5./9.)*(Tf-32)
ax1 = subplot(111) # y-axis in F
ax2 = twinx() # y-axis in C
def update_ax2(ax1):
y1, y2 = ax1.get_ylim()
ax2.set_ylim(Tc(y1), Tc(y2))
# automatically update ylim of ax2 when ylim of ax1 changes.

This works nicely. Thank you JJ.

John,
These ideas have been part of motivation behind my axes_grid toolkit.
In the module documentation of
"lib/mpl_toolkits/axes_grid/axislines.py", I tried to briefly explain
what I wanted and what I implemented, although the explanation is very
far from complete (also some examples are found in
