Playing with Graphs part 2

I did it. With a heck of a lot of help from the support staff at Pachube, I can now read the data for whatever period I want and graph it. I don't have an illustration on the web yet because it takes time to gather the data and people get tired of waiting and just click off somewhere else.

However, this is so cool. I can sample data at one minute intervals for, say an hour, any hour, any day, for the last year (or however long I have had the sensor running) and look at it in detail. Ever wonder what happens when the clouds block the sun from your solar heater sensor? What happens to the pump power demand when the sun comes back. I know all about this now.
