Is there a way to access area's plot->dc? For this example I wanted to
ask if the mouse was within 2 pixels of any point.
There's unfortunately not. But if your plots don't have axis
transforms (i.e. have the identity transform), it's a linear function,
so you can apply dc->plot to two points and derive it from the return
values.
