Dynamic chart
 

I think the best way to ask the question is to explain what I have
first.
I created a trending system for a bunch of machines in my company.
Basically I pull out such things as voltage, current, temp, gas flow,
pressure, cycle time, cycle name along with date and time.

In all I am trending 35 different things.
What I would like to be able to do is use a pull down window to grab
any of the items I am trending over any given range of dates.
So bassically I would like to be able to graph anywhere between 35 -1
things between any given date.

Please help
