Yes, it is fine.

Thanks. It looks like your approach provides a subset of what mine does, 
with probably the benefit of better performance. Am I correct that for a 
given series, the markers are all the same, that is, they all point in 
the same direction and are the same length?
With my code, each data point gets a different direction (though they 
are all the same length -- maybe I should change that). You could set 
them to be all the same to get similar results to your approach.
This brings up another question: Could you have created a custom marker 
without having to patch the code, but rather using the existing API? If 
not, that would be a good feature to add.
