This creates internal semantic structures: While Artists currently contain a long ist of artist properties with various purposes, we may simplify them by grouping properties by concerns. I anticipate that this will make it easier to reason about them. Also this can enable new features like multiple artists sharing styles, or dynamic style updates.\n\n#### Additional information\n\nFor a start, this would be an internal change, without any modification to the public Artist API.\n\nAs an example, I could see the following Line2D properties grouped into a style:\n- alpha\n- antialiased\n- color or c\n- dash_capstyle\n- dash_joinstyle\n- dashes\n- drawstyle\n- fillstyle\n- gapcolor\n- linestyle\n- linewidth\n- marker\n- markeredgecolor\n- markeredgewidth\n- markerfacecolor\n- markerfacecoloralt\n- markersize\n- markevery\n- path_effects\n- rasterized\n- sketch_params\n- snap\n- solid_capstyle\n- solid_joinstyle\n\nThis would reduce the non-stype properties to:\n- animated\n- clip_box\n- clip_on\n- clip_path\n- data\n- figure\n- gid\n- in_layout\n- label\n- mouseover\n- picker\n- pickradius\n- transform\n- url\n- visible\n- xdata\n- ydata\n- zorder\n\n### Proposed fix\n\n_No response_","author":{"url":"https://github.com/timhoffm","@type":"Person","name":"timhoffm"},"datePublished":"2025-12-09T11:12:59.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":6},"url":"https://github.com/30828/matplotlib/issues/30828"}
