Hi, calling show returns the following error using the numpy maskedarray branch.

I haven't personally done any testing with the maskedarray branch myself, though I know Eric Firing has done a little. > /usr/local/lib64/python2.5/sitepackages/matplotlib/path.pyc in > __init__(self, vertices, codes) > 118 len(vertices), self.code_type) > 119 codes[0] = self.MOVETO > > 120 vertices = ma.compress(npy.invert(mask1d), > vertices, 0) > 121 vertices = npy.asarray(vertices) > 122 codes = npy.where(npy.concatenate((mask1d[1:], > mask1d[:1])), > > AttributeError: 'module' object has no attribute 'compress' This seems to work if you change it to npy.compress  for both the "default" ma and the maskedarray branch. I'll go ahead and commit this change, though there may be performance implications.

I'm using it routinely, but have not been doing any great variety of plots. I might have hit that bug a few days ago, but if I did I worked around it instead of investigating. > >> /usr/local/lib64/python2.5/sitepackages/matplotlib/path.pyc in >> __init__(self, vertices, codes) >> 118 len(vertices), self.code_type) >> 119 codes[0] = self.MOVETO >> > 120 vertices = ma.compress(npy.invert(mask1d), >> vertices, 0) >> 121 vertices = npy.asarray(vertices) >> 122 codes = npy.where(npy.concatenate((mask1d[1:], >> mask1d[:1])), >> >> AttributeError: 'module' object has no attribute 'compress' I reported the absence, and Stefan van der Walt has already put a version in svn. The whole block of code can be streamlined and sped up a bit; I will commit a change to do that. Eric

I wonder if Eric's changes (which are quite different) fix David's scalar mask problem...?
