I'm marking this PR as ready to review. But in my mind, I wanted to open a discussion with you to cursor's form and legend markers. If you prefer, I'll mark it as a draft again.

thanks for the PR, i will take a look soon.

however, i definitely prefer to discuss things like this in an issue/proposal first instead of getting a random code dump without prior context. it will help you better align your PRs with future changes and understand where things are headed that are not immediately obvious from the repo code or conversations.

#431

i've been thinking long term about rendering markers on a dedicated canvas layer, which would fix the misalignment issues between DOM and canvas: #922

i'm currently experimenting with fast svg pathstring marker rendering in https://github.com/leeoniya/uMarks

I'll work on pixelAlign next.

if you attain an improvement, maybe put that into a separate PR (if it improves the existing hover point alignment)

also, please leave the build files out of PRs for easier review. i will do a build commit when the PR is merged.

Today, the example to override the point form (draw-hooks.html) is not performant. In order to draw the custom point, the points.show function is overidden; this force the drawing of every point, regardless of the serie's size.

this may be true of the demo, but this callback does receive all the necessary arguments needed for conditional point visibility. it does require copying some code, though.
