I am using the following command line to change the text of a figure's default legend:

legend('820mm','750mm','680mm','585mm','470mm','Location','NE');

but would like to add what the measurements relate to in a LEGEND TITLE, eg. 'Panel sizes (mm)'. Then I don't have to have 'mm' on every line and don't have to say what they measure elsewhere.

Shouldn't be difficult but can't find it in help. Would somebody kindly help please?

Thank you.

There is a lot of information buried in layers of handle graphics. You can do the following:

hleg = legend('820mm','750mm','680mm','585mm','470mm','Location','NE');
htitle = get(hleg,'Title');
set(htitle,'String','Panel sizes (mm)')

Use get(htitle) to see a lot of other properties you can manipulate.

I believe there are easier options in more recent versions of MATLAB. Certainly the R2016a online documentation for legend suggests that you can simply call

title(hleg, 'Panel sizes (mm)').
