To load a trend into a Selected Trend field, right-click the field. A menu appears allowing you to select a trend or clear the field. Once you have loaded your selected trends, you can make a particular pen the focus of the graph by clicking this field. An arrow to the left of the field indicates it is currently the focus trend.
