I've been relying very heavily on the examples lately to test my refactored branch of matplotlib. In doing so, I've discovered a few that are currently broken in matplotlib's trunk. I'm reporting these just to bring them to the attention of the list, not because they are priority bugs for me. Some of these may simply be old and should be removed. Let me know if you need any more information for them. I've also run backend_driver.py through a code coverage tool (coverage.py) and identified a few large parts of the code that weren't covered. I added a dozen or so existing examples to backend_driver, and now though there are lots of little places that never get run (mainly error cases and such), the code coverage of backend_driver is quite good. The only high-level method in axes.py that isn't being tested is cohere(). Does anyone have a test for it that could be added? Errors follow.
