In 3.0.0, it barfs.\r\n\r\nIs there a different way to set this?  I don't see any rcParams keys that reference drawstyle or look like they could be impacting drawstyle\r\n\r\n**Code for reproduction**\r\n\r\n```\r\nPython 3.5.4 |Continuum Analytics, Inc.| (default, Aug 14 2017, 13:26:58)\r\nType 'copyright', 'credits' or 'license' for more information\r\nIPython 6.1.0 -- An enhanced Interactive Python.
