Hi,

I have two sets of data and I am plotting both on the same chart. I need
them to have separate y axes, because they have different ranges. When I
select one data set and force it onto a secondary y-axis, it stops
plotting
on the log-x axis, and instead plots over an imaginary linear x axis. So,
for instance, value x=4871 y=1.29 plots at 1.29 on the secondary y axis
and
at about 900 on the log x axis. Anyone know of a fix?

Thanks
-Tom
