circle-stroke marker renders black instead of white by default

[RobinKohrs]

According to the documentation, the default fill color of the circle-stroke marker should be white. However, in my case, all circle-stroke markers are rendering as black.

I tried inspecting the source code and assumed the fill option might control this behavior. However, it appears that setting fill results in an attempt to render the marker as a polygon

It’s possible I’m misunderstanding how the fill behavior is implemented or intended to be used. Any clarification or guidance would be very much appreciated.

Can you post the code that is not working as you expect?

By "circle-stroke marker", do you mean the Dot mark?

It is working as expected for me:

No sorry, that wasn't clear... I meant the "circle-stroke"-option for data-points in a Line-Marker like here

What is happening here is that the fill of the marker is being set to a CSS variable var(--svelteplot-bg) (rather than white).

I think this is so that the color can switch between light and dark mode, but it does mean that the references to "white" in the marker options section of the docs are incorrect.

As a work-around, you can either:

• define this CSS variable to be white (https://svelte.dev/playground/89ac35e244724360b89a288a6d6730b3?version=5.34.3)
• use separate Line and Dot marks (https://svelte.dev/playground/a3f97af257674a969f28b4b740aaa514?version=5.34.3)
