Select Data Selected by Brushing - Move To New Plot from the Graph Data Editor shortcut menu or the Graph Data Editor Layouts menu to add a new plot to the Graph Data Editor (and the graph). As in Copy to New Plot, one line will be copied for each case in the Graph Data Editor from the original plot (i.e., one for each point on the graph), but only those points selected by brushing will be represented by non-missing values in the new plot. The brushed cases are effectively moved to a new plot, i.e., when Move to New Plot is selected, the brushing-selected cases in the original plot in the Graph Data Editor will be set to missing values.
