How can i select the persistence to show in habmin?

Hi,

i persist some items in rrdj and 4dbo persistence.

How can i change the used persistence for drawing the graphs in habmin?

Or do i have to use two items for this? One persisted in rrd4j and one item with another name persisted with 4dbo?

See the Chart element:

You provide the name of the persistence store to get the data to chart from with the service tag.
