In the plot, the blue fill should be between the red and green line.\r\n\r\n**Matplotlib version**\r\n\r\nThis is with Matplotlib 2.0.0.\r\n(on Macports, but I don't think that matters)","author":{"url":"https://github.com/cdeil","@type":"Person","name":"cdeil"},"datePublished":"2017-05-15T14:28:05.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":11},"url":"https://github.com/8623/matplotlib/issues/8623"}
