And this method is missing from LogLocator. (`set_params` is indeed defined in `MaxNLocator` https://github.com/matplotlib/matplotlib/blob/master/lib/matplotlib/ticker.py#L1297)\n\nSo my question is: shouldn't all `Locator` subclasses have a `set_params` method ?\n\n(and then, my code example could raise a _different error_, or maybe a _warning_,  complaining that `LogLocator` makes in fact no use of an `nbins` parameter!)\n\nbest,\nPierre\n","author":{"url":"https://github.com/pierre-haessig","@type":"Person","name":"pierre-haessig"},"datePublished":"2014-10-17T14:00:00.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/3658/matplotlib/issues/3658"}
