If the ConnectionType property is set to 1 (local connection) or 2 (remote connection), then the value of this property must be set, for example, to string "group1", where group1 is a value defined in the "PmaTrendGroup > Trend > Trend group identifier" configurator.

	// or

	oTrend.ConnectionGroup = "GroupX";
