This doesn't seem to be happening.\n\nExample:\n```\nimport control as ct\nsys1 = ct.rss(4, 2, 2, strictly_proper=True)\nsys2 = ct.rss(4, 2, 2, strictly_proper=True)\nct.singular_values_plot([sys1, sys2])\n```\ngenerates\n\n![Image](https://github.com/user-attachments/assets/66f2d7dd-3413-42bd-a3cf-e007676a69a6)\n\nThe following code works correctly in terms of colors:\n```\nct.singular_values_plot(sys1)\nct.singular_values_plot(sys2)\n```\n\n![Image](https://github.com/user-attachments/assets/8b589767-463f-4793-8276-432058588811)\n\nNote that the range of frequencies is different for each system, which is the reason you want to be able to call them as a list.","author":{"url":"https://github.com/murrayrm","@type":"Person","name":"murrayrm"},"datePublished":"2025-03-02T02:04:15.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/1134/python-control/issues/1134"}
