This happens because PGFPlots only uses one "stack" per axis: You're stacking the second confidence interval on top of the first. The easiest way to fix this is probably to use the approach described in "Is there an easy way of using line thickness as error indicator in a plot?": After plotting the first confidence interval, stack the upper bound on top again, using stack dir=minus
. That way, the stack will be reset to zero, and you can draw the second confidence interval in the same fashion as the first:

You can add every axis/.append style={font=\tiny},
before every axis x label/.style
. In this way you don't need to use \tiny
in x-y-z-labels.
To hide z axis just add hide z axis,
after axis z line=center
. I believe that if you put only axis z line=none
you are hiding only the axis line but not the ticks that are the short lines in your image. They are in that position because with axis z line=none
the z-axis
is no more centered.
