When the mouse cursor move on the inset axes the cursor don't move.\n\n### Code for reproduction\n\n```python\nimport numpy as np\r\nimport matplotlib.pyplot as plt\r\nfrom matplotlib.widgets import MultiCursor\r\n\r\n# Fixing random state for reproducibility\r\nnp.random.seed(19680801)\r\n\r\n# some random data\r\nx = np.random.randn(1000)\r\ny = np.random.randn(1000)\r\n\r\n\r\ndef scatter_hist(x, y, ax, ax_histx, ax_histy):\r\n    # no labels\r\n    ax_histx.tick_params(axis=\"x\", labelbottom=False)\r\n    ax_histy.tick_params(axis=\"y\", labelleft=False)\r\n\r\n    # the scatter plot:\r\n    ax.scatter(x, y)\r\n\r\n    # now determine nice limits by hand:\r\n    binwidth = 0.25\r\n    xymax = max(np.max(np.abs(x)), np.max(np.abs(y)))\r\n    lim = (int(xymax/binwidth) + 1) * binwidth\r\n\r\n    bins = np.arange(-lim, lim + binwidth, binwidth)\r\n    ax_histx.hist(x, bins=bins, label=\"X\")\r\n    ax_histy.hist(y, bins=bins, orientation='horizontal', label=\"Y\")\r\n    \r\n# Create a Figure, which doesn't have to be square.\r\nfig = plt.figure(layout='constrained')\r\n# Create the main axes, leaving 25% of the figure space at the top and on the\r\n# right to position marginals.\r\nax = fig.add_gridspec().subplots()\r\n# The main axes' aspect can be fixed.\r\n\r\n#ax.set(aspect=1)\r\n# Create marginal axes, which have 25% of the size of the main axes.  Note that\r\n# the inset axes are positioned *outside* (on the right and the top) of the\r\n# main axes, by specifying axes coordinates greater than 1.  Axes coordinates\r\n# less than 0 would likewise specify positions on the left and the bottom of\r\n# the main axes.\r\nax_histx = ax.inset_axes([0, -0.25, 1, 0.12], sharex=ax)\r\nax_histy = ax.inset_axes([-0.25, 0, 0.12, 1], sharey=ax)\r\nax_plus = ax.inset_axes([1.05, 0, 0.02, 1])\r\n# Draw the scatter plot and marginals.\r\nscatter_hist(x, y, ax, ax_histx, ax_histy)\r\n\r\n\r\nmulti1 = MultiCursor(None, (ax, ax_histx), useblit=False, horizOn=False, vertOn=True, color='r', lw=1)\r\nmulti2 = MultiCursor(None, (ax_histy, ax), useblit=False, horizOn=True, vertOn=False, color='r', lw=1)\r\n\r\n#ax.set_aspect(0.5)\r\n\r\nplt.show()\n```\n\n\n### Actual outcome\n\n\r\nhttps://github.com/matplotlib/matplotlib/assets/65216088/7fcdd145-8fbf-4903-96f4-64ad50f29a06\r\n\r\n\n\n### Expected outcome\n\nThe cursor move following mouse for all axis.\n\n### Additional information\n\n_No response_\n\n### Operating system\n\nUbuntu\n\n### Matplotlib Version\n\n3.1.6\n\n### Matplotlib Backend\n\nQtAgg\n\n### Python version\n\n 3.10.6\n\n### Jupyter version\n\n_No response_\n\n### Installation\n\npip","author":{"url":"https://github.com/jlocatelli74","@type":"Person","name":"jlocatelli74"},"datePublished":"2023-06-30T14:48:27.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/26225/matplotlib/issues/26225"}
