Re: fill_bw_xy error

Hi Jinqiang,

The code is a little complicated to debug without being able to actually run it. I created an example that seems to work for me, although I do get a warning:

(0) fill_bw_xy: Error: If filling between two curves, one set must be 2D, and the other 1D.

Can you try running the attached and let me know if it works for you?

The weird thing that I don't quite understand is that the Y2 curve is appearing on top, even though the Y3 curve was added last. Is this the issue you are talking about?
