There used to be a [subplot example](https://matplotlib.org/2.1.2/gallery/animation/subplots.html), but \u003cstrike\u003ethat was back when it was overly complicated to do animated subplots.\u003c/strike\u003e it was removed in #10125\r\n\r\n### Suggested improvement\r\n\r\nAdd a new example showing how animation on subplots work. I originally thought of merging existing examples but they all feel overly complicated so I think this should be super simple, like 3 plots: sine/cosine/tangent and two lines each in the style of https://matplotlib.org/devdocs/gallery/animation/simple_anim.html#sphx-glr-gallery-animation-simple-anim-py\r\n\r\nI was thinking something like this, but if there's an easier or alternative, we should probably show that (too/instead of):\r\n\r\n```python\r\nimport numpy as np\r\nimport matplotlib.pyplot as plt\r\nimport matplotlib.animation as animation\r\n\r\nfig, (ax1, ax2, ax3) = plt.subplots()\r\n\r\nx = np.arange(0, 2*np.pi, 0.01)\r\nline1, = ax1.plot(x, np.sin(x))\r\nline2, = ax2.plot(x, np.cos(x))\r\nline3, = ax3.plot(x, np.tan(x))\r\n\r\ndef animate(i):\r\n    line1.set_ydata(np.sin(x + i / 50))  # update the data.\r\n    line2.set_ydata(np.sin(x + i / 50)) \r\n    line3.set_ydata(np.sin(x + i / 50)) \r\n    return [line1, line2, line3]\r\n\r\n\r\nani = animation.FuncAnimation(\r\n    fig, animate, interval=20, blit=True, save_count=50)\r\n\r\n```","author":{"url":"https://github.com/story645","@type":"Person","name":"story645"},"datePublished":"2022-09-16T14:14:05.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":7},"url":"https://github.com/23909/matplotlib/issues/23909"}
