Or, maybe not. Somebody else is going to have to work on the "Why?" for you. I'm retired. But, I will say I never imagined that anyone would ask for a black background, especially in a PDF file. This will give you a black background on the display, and a white background in your PDF file. I think that is what most people want. I'm really not sure what YOU want. :-)
cgWindow, WMulti=[0,1,2], background='black'
cgPlot, x1, y1, /Addcmd
cgPlot, x2, y2, /AddCmd
