Re: [Numpy-discussion] numpy, matplotlib and masked arrays
Hi Pauli, Thanks for that. The script does not work in either EPD-6.1-1 or EPD-6.2-2 (the current release, see original post) on Ubuntu, so not supporting EPD-6.1-1 doesn't solve the problem unfortunately. However, your test suggests that it is not simply the change from numpy 1.3.0 to 1.4.0. This leaves either the EPD or the combination of numpy 1.4.0/matplotlib 0.99.3 on Ubuntu. I've never tried installing from the source, maybe that's where it's heading.

I've been trying to wean myself off Windows and migrate to Linux, so far a rewarding and mostly enjoyable experience, while developing a Python-based quality control and post-processing system for ecosystem time series data. The end users will be on Win, MacOS and Linux, so unfortunately your elegant if somewhat non-pythonic suggestion doesn't quite help.
