However, no matter what settings are input into `GridSpec`, the parent figure is divided into equally sized subfigures. Doing this same process with `Figure.add_subplot` produces the expected results with the axes bounded by the input extent and separated by the correct `hspace` and `wspace`.\n\n### Code for reproduction\n\n```Python\nimport matplotlib.pyplot as plt\r\nfrom matplotlib.gridspec import GridSpec\r\nimport numpy as np\r\n\r\ndpi = 100\r\nwidth = 600\r\nheight = 600\r\n\r\nmain = plt.figure(figsize=(width / dpi, height / dpi), dpi=100,\r\n                  facecolor='#9a9a9a', frameon=False)\r\n\r\ngs = GridSpec(2, 4, left=.1, right=.9, bottom=0.1,\r\n              top=0.9, wspace=0.15, hspace=0.15)\r\n\r\ncolors = np.array([\r\n    ['red', 'black', 'green', 'blue'],\r\n    ['brown', 'gray', 'white', 'gold']\r\n])\r\n\r\npanels = []\r\nfor row in range(2):\r\n    for col in range(4):\r\n        main.add_subfigure(gs[row, col], facecolor=colors[row][col])\r\n\r\nplt.show()\n```\n\n\n### Actual outcome\n\nThe output is equally sized subfigures without any space between them and the full extent being used despite the input restrictions.\r\n![test_add_subfig](https://github.com/matplotlib/matplotlib/assets/13972103/aa289a95-97a9-428c-a3c4-30e610117858)\r\n\n\n### Expected outcome\n\nWhat is expected is a properly spaced areas with the proper extent. This can be produced when using `add_subplot` instead of `add_subfigure`.\r\n![test_add_subplot](https://github.com/matplotlib/matplotlib/assets/13972103/dbdab0bc-1232-44f1-8877-5e4960656a07)\r\n\n\n### Additional information\n\n_No response_\n\n### Operating system\n\n_No response_\n\n### Matplotlib Version\n\n3.8.3\n\n### Matplotlib Backend\n\n_No response_\n\n### Python version\n\n3.12.2\n\n### Jupyter version\n\n_No response_\n\n### Installation\n\nconda","author":{"url":"https://github.com/nawendt","@type":"Person","name":"nawendt"},"datePublished":"2024-04-24T15:08:53.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/28132/matplotlib/issues/28132"}
