Hold on a second here... why isn't this method in the base class? Is the check different in the Axes class? I just did a quick looking around at the other PRs related to this one, and they don't seem to do the check in the same way. I am confused. |

Yes, I was going to suggest the same thing; move implementation into the base class and use it there as well. |

I just noticed that the 3d limit functions now converts the limit twice. I don't think we have any tests that applies units for 3d axes, so this wouldn't have been noticed in the previous PR. |

The method name is a bit misleading. It validates the converted limit. Also, the docstring doesn't say that it returns anything useful, nor that None can be an input.

I'll change the name to _validate_converted_limits . Should I change the docstring to """ Raise ValueError if converted limits are non-finite.
Note that this functions also accepts None as a limit argument.
Returns : limit value after call to convert_xunits() or convert_yunits() or convert_zunits()""" ?

Name is good. A slight tweak to that docstring,
"Returns : The limit value after call to convert(), or None if limit is None."

This is so much cleaner! Thank you for this!

Fix it here in this PR. It is relevant to what you are fixing up. |

Just a couple of typos.
One thing that we lose with this overall change that was nice is the exception message saying which axis was problematic; it also said what the original limits were. I think the trade-off is fine since we can figure out the problematic axis by looking at the traceback, and debugging can get us the values.

More lines removed than added: I love it! I'll wait for the CI and @WeatherGod to change his review status before merging.

Will merge once Travis and friends are done. Thanks for bearing with me, and sorry for not noticing these issues in the previous PRs. |
|
Not an issue and thank you too for helping me :) |

In addition to my previous PR ( #8022 ), this one places the check in the
_validate_axes_limits()function in/lib/mpl_toolkits/mplot3d/axes3d.pyon the converted limits rather than on the limits passed to the function
