Show the min/max data in funky purple shading

Browse source 
Dirk likes purple. I mean - Dirk REALLY likes purple.

And what's better than "purple"? You got it: "funky purple".

So this shows the one- two- and three-minute min/max information in some
seriously funky purple fringing.  It's not really necessarily meant to
be serious, but it's a quick hack to visualize the data until we figure
out what to *really* do with it.
