Legend compatibility help

Could someone with access to Matlab run the following?

## Test if there is a listener on DisplayName property
h = plot (rand (3,3));
hl = legend ();
## At this point, legend is data1, data2, data3
set (h(1), 'DisplayName', 'This is a Long String')
## Is legend updated?

## What about doing?
legend hide
legend show
## Is legend updated now?

## What does Matlab display for surface objects?
z = peaks ();
surf (z);
hl = legend ("surf1");
print -dpng surfleg.png

## Similarly, what does Matlab display for contour objects?
contourc (z);
hl = legend ("contour1");
print -dpng contourleg.png

Thanks in advance,
Rik
