I am trying to create a very simple graphing program. The point of the program is to be able to graph many transparent lines so that you can quickly judge the variation between different samples by eye. Anyway, what I have so far looks good on the screen, however, when I try to print it all the lines become opaque. All I have done is use IB to connect the print menu item to the print: IBAction of the view my graph is in (the print method is inherited from NSView). What am I missing?
