Just like the style in MATLAB? The current new Matplotlib defaults generate grid lines that look too pronounced.\r\n\r\nIn fact, when using Matplotlib 2.0+, I always use `plt.grid(ls=':')` instead of just `plt.grid()`. It looks much better.\r\n\r\n(2) The `zorder` behavior, if set to None, is undefined, or at least not documented clearly.\r\n\r\nFor example, I tried the following codes respectively:\r\n\r\n`plt.figure(); plt.plot([0,1],[0,1],lw=10); plt.grid()`\r\n`plt.figure(); plt.plot([0,1],[0,1],lw=10,zorder=None); plt.grid()`\r\n`plt.figure(); plt.plot([0,1],[0,1],lw=10); plt.grid(zorder=None)`\r\n`plt.figure(); plt.plot([0,1],[0,1],lw=10,zorder=None); plt.grid(zorder=None)`\r\n\r\nand I am getting confusing results.\r\n\r\nThere is indeed some needs to pass `None` to `zorder`, especially when designing wrapper functions where `zorder` sometimes needs to be specified by the user, and sometimes doesn't.","author":{"url":"https://github.com/jsh9","@type":"Person","name":"jsh9"},"datePublished":"2017-11-14T22:49:51.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":19},"url":"https://github.com/9785/matplotlib/issues/9785"}
