Ryan,

I don't think these calls should be removed. Would you convert them to
asanyarray() instead? That will preserve the masked arrays.

Log Message:
-----------
Remove calls to np.asarray(). This was breaking the use of masked arrays in calls to set_[x|y]data() and is handled appropriately already by set_data().

Darren,

I couldn’t find a case where those calls weren’t already duplicated when set_data() was called. According to the code, np.asarray() will be called if ma.isMaskedArray() returns false. Am I missing something?

No, I didn't realize it was called in set_data.
