"legend" command does nothing

I remember missing fonts were raised as a possible culprit when I was having
trouble with text appearing on plots.  I checked my Font Book at that time
and performed a "resolve duplicates" on all of my fonts.  Then, as now, I
haven't been able to find any duplicate fonts.

Adrian,

missing fonts have cropped up a few times - so far the most common cause
were broken fonts - please check your Font Book for duplicate or broken
fonts (most specifically Arial). Please let me know if that was the cause.

Thanks,
Simon

Hello,

I am having problems adding legends to my plots.  For example, the

command

at the bottom of this message produces no legend for me.  The plot

appears

correctly, but the legend is completely absent.  Am I doing something
incorrectly in the syntax of the legend function?

It is possible that this is related to a problem that I posted previously

on

this list: I do not see any text on any graphs unless I explicitly supply
the "family="sans"" argument to any plotting function.

Any advice is appreciated.  Thank you,
Adrian Down
