My scripts would therefore save me significant amount of time if e.g. for \"abcd123.dat\" they suggested to export into \"abcd123.*\".\r\n\r\nRationale 2: One old question about this can be found on SO (https://stackoverflow.com/questions/41680007/how-to-change-default-filename-from-matplotlib-navigationtoolbar-in-a-pyqt5-appl) and the proposed solution requires monkey-patching Matplotlib functions - which is ugly, tedious and most importantly, the suggested code did not work anymore. \r\n\r\n### Proposed solution\r\n\r\nLet's allow users to change the filename too, allowing one to simply set:\r\n\r\n     matplotlib.rcParams[\"savefig.basename\"] = ...","author":{"url":"https://github.com/FilipDominec","@type":"Person","name":"FilipDominec"},"datePublished":"2024-02-12T09:37:06.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":15},"url":"https://github.com/27774/matplotlib/issues/27774"}
