If it is not acceptable to to remove this call, can we have option to tuning this?\n","author":{"url":"https://github.com/Kojoley","@type":"Person","name":"Kojoley"},"datePublished":"2016-07-08T12:50:53.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/6705/matplotlib/issues/6705"}
