This leaves them without preview images in the gallery.\n\n## Proposed Plan\nFor each example, use `sphinx_gallery_thumbnail_path` in the docstring pointing to a manually captured screenshot saved in the `images/` folder.\n\n### Examples I can cover:\n- `embedding_in_tk_sgskip.py` (Tkinter — already done in #31365)\n- `embedding_in_qt_sgskip.py` (PyQt5)\n- `embedding_webagg_sgskip.py` (WebAgg)\n- `toolmanager_sgskip.py`\n- `svg_histogram_sgskip.py`\n- `svg_tooltip_sgskip.py`\n- `canvasagg.py`\n\n### Examples needing GTK/wx contributors:\n- All gtk3/gtk4 examples (Linux only)\n- All wx examples (need wxPython)\n\n## Question\nShould the screenshots be PNG or can SVG be used directly for the svg_* examples?","author":{"url":"https://github.com/buddy0452004","@type":"Person","name":"buddy0452004"},"datePublished":"2026-03-25T07:15:39.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":7},"url":"https://github.com/31378/matplotlib/issues/31378"}
