title: How to control a NSView, located in a dedicated NSWindow, from the main NSWindow designed to support the GUI built under COCOA?
body: <p>This is probably a simple problem for the high skilled Cocoa programmers, but I can't find how to control the graph in a separate window. I read carefully the Cocoa related books, go through many web notes,but I can't find a solution to my problem. The purpose is to use a dedicated window to draw the I=F(Vg) curves extracted by the GUI from a specific hardware. All the GUI and the hardware works fine ( thanks to the help provided by several members of stackoverflow) , but no way to send the parameters to the NSView to display the results.
  So far, the GUI class is based on a NSObject, the graphic class is NSView.
  Any idea, examples, links will be appreciated. Thank you so much.
