Thanks for these tips; I hadn't known about glSwapAPPLE() and I am
using double buffering. (and MacFOH -> very nice GUI!)
I am almost certain that this isn't an OpenGL error per se, but maybe
an error related to subclassing NSOpenGLView and then placing it in a
subclassed NSView: before I had the labeled axes, I only instantiated
HistoryGraphView (the NSOpenGLView subclass that now doesn't display
unless I constantly resize the window) in the nib and it drew itself
correctly then.

The Cocoa way:
[[aHistoryGraphView openGLContext] flushBuffer];
Instead, if you're double-buffered, call glSwapAPPLE() after drawRect:
returns, or if single-buffered call glFlush().
