I would like to know if there is any method to do something like this:

As you can see, I have some pens on the first easy chart and made a copy, then turned off the pen control for the copied easy chart.  
What I would like to do, is have the pen control, control both charts OR somehow setup the easy chart component to display 2 different sets of pens by using a WHERE clause to denote a different Furnace.  
Any ideas?

how are your tags setup? are each furnaces tags stored in an individual folder?

Yes, all I’d have to do is change the Folder Path to link to a different furnace.

should be pretty easy to have a script that grabs the first easy charts tagpens dataset then run thru and replace the folder portion of the tagpath in the tagpath column with the other furnace name. Then you can bind the date start/end to the first chart also.

Like this both charts should respond to tags being enabled disabled and any date range changes.
