I'm not sure what kind of annotation rectangle you are using, but if you are
using something like legend() then what you need to know is that it constructs
a separate axis in the figure, and that axis is normally on top. If you move
the legend axis using uistack() or setting the children order of the figure,
then the legend will move underneath the axis that contains the pcolor and the
line plot. Thus, the solution is to pcolor, then legend(), then find the
parent axis of the pcolor() and create a third axis that is the same size but
has 'axis', 'off' (so you don't overwrite the lower tick marks) and has the
same Position and InnerPosition as the axis for the pcolor, and has 'Color',
'none' so that it is transparent. Then draw the line plot in that third axis,
either by specifying the axis number as the first parameter to plot(), or by
specifying the axis number as the 'Parent' property for the plotting command.
