To determine whether a gate is visible on a 2D plot or to show or hide a gate, right-click on the plot and select Show Gates from the pop-up menu. A submenu will appear listing all currently defined gates. Clicking on the desired gate in the list will toggle between showing or hiding the gate.
You can also hide a visible gate directly from a 2D plot:
1. Activate the gate that you wish to hide, by clicking inside it.
2. Press the Delete key.
3. Select the Hide button in the dialog box that appears.
Note: A 2D gate can only be displayed if the axes on the plot match the axes that were used when the gate was first created. However, color dot plots can display backgated populations for any gate in your layout.
