Here is an example:\n\n``` python\nimport matplotlib.pylab as plt\nmarker_size=10\nplt.figure()\nplt.subplot(221)\nplt.plot(\n        range(10),\n        linestyle='--',\n        )\n# drawing a line looks fine\nplt.subplot(222)\nplt.plot(\n        range(10),\n        marker='o',\n        markersize=marker_size,\n        markeredgewidth=2,\n        markeredgecolor='r',\n        )\n# drawing markers is a bit problematic. There is always a line associated with markers.\nplt.subplot(223)\nplt.plot(\n        range(10),\n        linestyle=' ',\n        marker='o',\n        markersize=marker_size,\n        markeredgewidth=2,\n        markeredgecolor='r',\n        )\n# In order to ONLY draw markers, 'linestyle' should be set an empty string.\nplt.subplot(224)\nplt.plot(\n        range(10),\n        linestyle='--',\n        linewidth=3,\n        marker='o',\n        markeredgewidth=2,\n        markeredgecolor='r',\n        markersize=marker_size,\n        )\n# It's even more strange that when you do want makers with a line, 'linestyle' also affects marker\n# edges. In this example, line is set dashed. Then the marker's edges get dashed too!\nplt.draw()\nplt.show()\n```\n\nThere are of-course ways to get around these problems, but wondering maybe this is a bug unexpected by maintainers.\n","author":{"url":"https://github.com/enfeizhan","@type":"Person","name":"enfeizhan"},"datePublished":"2015-04-15T06:49:43.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":20},"url":"https://github.com/4338/matplotlib/issues/4338"}
