When you create the legend, the function returns the handle to the legend.

        h = legend (...)

You may also obtain the handle by ...

        h = findobj (gca (), "tag", "legend");

The legend object is type "axes" and with 6 unique properties. They are 
"edgecolor", "location", "orientation", "string", "textcolor", and 
"textposition".

edgecolor: sets to color of the box around the legend axes (when boxon is set)

location: is one of "north", "south", "east", "west", "{northeast}", 
"southeast", "northwest", "southwest", "northoutside", "southoutside", 
"eastoutside", "westoutside", "northeastoutside", "southeastoutside", 
"northwestoutside", or "southwestoutside".

orientatation: is either "vertical", or "horizontal".

"string": Is a cell string array containing the strings describing the graphics 
objects.

textcolor: Is the color of the text objects.

textposition: May be "left" or "right" and specifies if the text is to the left 
of right of the graphics objects icons.

You may change the location and text descriptions by ....

        plot (rand (2))
        h = legend ({"foo", "bar"})
        set (h, "location", "west")
        set (h, "string", {"hello", "world"})
