     '''Create a plot that compares the shapes of backgrounds versus signal.
-    Backgrounds will be stacked together and signals will be plot separately.
+    If stackBkg, backgrounds will be stacked together and signals will be plot separately.
     Total background and signals are scaled to 1 if scale == True. Inputs organized 
     as dicts so that keys can match across dicts (ex. bkgs and bkgNames).
 
     @param outfilename (string): Path where plot will be saved.
+    @param year (int): Year to determine luminosity value on plot. Options are 16, 17, 18, 1 (for full Run II),
+        or 2 (for full Run II but represented as separate years, ie. 2016+2017+2018).
     @param prettyvarname (string): What will be assigned to as the axis title.
     @param bkgs ({string:TH1}, optional): Dictionary of backgrounds to plot. Defaults to {}.
     @param signals ({string:TH1}, optional): Dictionary of signals to plot. Defaults to {}.
     @param names ({string:string}, optional): Formatted version of names for backgrounds and signals to appear in legend. Keys must match those in bkgs and signal. Defaults to {}. 
     @param colors ({string:int}, optional): TColor code for backgrounds and signals to appear in plot. Keys must match those in bkgs and signal. Defaults to {}.
     @param scale (bool, optional): If True, scales total background to unity and signals (separately) to unity. Defaults to True.
+    @param stackBkg (bool, optional): If True, backgrounds will be stacked and the total will be normalized to 1 (if scale==True). Defaults to False.
