#CONNECTSTO (Optional construct): The integer numbers which follow CONNECTSTO represent a pane in the realtime [[Dashboard|dashboard]]. When clicked on that pane this chart appears. This is only valid on charts in the default output. For other outputs there is no semantics for CONNECTSTO and a warning is issued in the logfile if it is specified in any second or higher output. | #CONNECTSTO (Optional construct): The integer numbers which follow CONNECTSTO represent a pane in the realtime [[Dashboard|dashboard]].
