There are several different ways to apply a gate to a plot such that only the events in the applied gate will appear in the plot:

 

•Create a Gate View from the Insert→General group. Press and hold the mouse button on the gate that you want to apply. While holding the mouse button down, drag and drop the gate from the Gate View list onto a plot.

 

•Open the Gate Navigator from the View tab→Navigators→Gate Navigator. Press and hold the mouse button on the gate that you want to apply. While holding the mouse button down, drag and drop the gate from the Gate Navigator onto a plot.

 

•Select a gate on a plot. While holding the mouse button down, drag and drop the gate to another plot.  If dragged to an empty spot on the layout, a new plot gated on that gate will be created.

 

•Select a plot or multiple plots and go to the Gating→Create Gates group. Select the gate from the Current Gates drop-down list.

 

•Right-click on a plot and select Format from the pop-up menu. Go to the Overlays category (see Formatting Single Parameter Histograms or Formatting 2D plots) and choose the gate you want to apply from the drop-down list.  This is a convenient for applying different gates to overlays on the same plot.

 

Note:  Different overlays on a plot need not have the same gate applied.
