I  am  following temperatures in my house and I want to feel the trend
of today compared to yesterday.

I  don't  want to overlap today's curve with all of yesterday but only
what  is missing between today "now" and the rest of the day that will
be filled with yesterday datas.

And I want Yesterday's curves to be draw with dotted style for better

As  a picture is faster to understand than words, here is what I would
like to reproduce : http://i.imgur.com/GcnX5M3.png

The beat is 1 min.

The grey bars are something that I also want to draw and is the 1 or 0
DS datas that show when boiler is on or off.

All datas are in same RRD.

Help would be appreciated.

Thank you.
