Pull-down menu that specifies the Data Series for which the QuickView data will be displayed. The user must first select the Subplot for which the QuickView data is to be displayed. If several Data Series are overlaid within the Subplot, then it will be possible to select the desired Data Series with this pull-down menu. If there is only one Data Series in the Subplot, then there will be only one Data Series in the pull-down menu and it is not necessary to make a selection.
