Sorry that's my fault for stuffing up the example. Here is the method in
question, the whole class would probably be too big. What I really want to do
is remove the hard coded values in initWithSize to be equal to the size of
the NSView called userGraph. Eventually I'm going to draw bar charts into the
image, but for now it just displays randomly placed squares. The NSLog output
shows that the size reported in NSSize ms is always 1081352192 for width and
0 for height.

-(void)drawGraph{
  NSImage *testImage = [[NSImage alloc] initWithSize: NSMakeSize(200,200)];
  srandom(time(NULL));
  NSRect r;
  NSPoint p;
  NSSize s;
  NSRect mr;
  NSSize ms;
  mr=[userGraph bounds];
  ms=mr.size;
  [testImage lockFocus];
  [[NSColor blueColor] set];
  int cx,cy,my;
   cx=0;cy=0;
   my=(random () % 20 ) + 2;
   for(cx=0;cx<200;cx+=6) {
         p.x=cx;p.y=my*5;
         s.width=5;s.height=5;
         r.origin=p; r.size=s;
         [NSBezierPath fillRect:r];
   my=(random () % 20 ) + 2;
   }
  [[NSColor whiteColor] set];
  [testImage unlockFocus];
  NSLog(@"Bounds");
  NSLog(@"%d %d",ms.width,ms.height);
  [userGraph setImage:testImage];
}
