Thanks for the great package, makes creating complex multi-panel figures much easier!","author":{"url":"https://github.com/mmagnuski","@type":"Person","name":"mmagnuski"},"datePublished":"2020-08-22T09:55:38.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/221/proplot/issues/221"}
