Why does my legend behave incorrectly in MATLAB 7.0.1 (R14SP1) after I have specified the "Units" property?

I create a plot with a legend using:

l = plot(1:10); 

L = legend(l, {'a'}); 

set(L, 'units', 'pixels'); 

set(L, 'units', 'normalized');

Then, if I try to change its location on the axis using, for example:

set(L, 'Location', 'north');

I expect the location of the legend to move to the upper center of the figure. However, the location does not change from the upper right.

Also, if I try to make the legend invisible using:

set(L, 'visible', 'off');

I find that the legend contents remain visible.

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

There is a bug in MATLAB 7.0.1 (R14SP1) in the way the LEGEND function properties are updated after the “Units” property has changed to anything other than “normalized”.

To work around this issue, avoid changing the "Units" property of the legend.

This bug has been fixed in MATLAB 7.1 (R14SP3).
