Re: Re: Problems with new plot widget

I think you'll find that axis_set_ticks() changes both the left and right axes
while axis_set_ticks() only changes the specified axis for the top and bottom
as it should.  A part of my graph that looked correct was actually displaying
the bug, because I invoked axis_set_ticks() twice yet three axes were correct.
(The graph was initialized as (0..1, 0..1).)

Thanks for the other information.  It should polish up my graphs considerably.
