Thank you! You have correctly restated my problem. I
think I need details though. I selected the lower x axis
and adjusted the scale from "Value (y) axix crosses
between categories" to "Value (y) axis crosses at maximum
category" or "Categories in reverse order". The y axes
flipped! However, on the left side of the chart only a
title appeared, with no actual y axis. I tried to find
this y axis but it appears to be missing.

What should I try next?


I think we may have a misunderstanding here. I think
the basis of the
misunderstanding is the assumption that the secondary
axes are on the
right/top of the screen, which is not necessarily true.
Allow me to restate
the problem so you can correct me if I have it wrong.

You want one x-axis, preferably at the bottom of the
screen. The x-axis
data for all series is the same and it is uniformly
spaced so that a value
and category axis looks the same. You want two y-axes,
the left y-axis
being percent cover and the right y-axis being
precipitation.

Did I get that right? If so, you can move the primary y-
axis to the right
and the secondary y-axis to the left side of your chart
(sort of a
flipflop). You can also flipflop the x-axes. The basic
idea is to select
an axis, Format | Selected axis | Scale tab, change the
value next to "(X or
Y) axis crosses at:." More details if you need it.
