Thanks @bclehmann, this is a great start! Pulling some convo from Discord (#1966)

I would like at a minimum to have less ugly arrows, a method in the plottable factory, and options to anchor the arrows on their midpoint, rather than the vector tail. Colormap support would be cool too

These are all good extensions for this plot type! I'll review and merge this PR in now, and refinements can be made in future PRs 👍

Note that I'm renaming RootedCoordinateVector.Tail to RootedCoordinateVector.Point since that location may become decoupled from the position on the arrow in a future revision

Also (let me know if I'm messing up here) I'm going to rename RootedCoordinateVector.Distance to RootedCoordinateVector.Magnitude because I think that word better matches the concept of a vector, and it may be representing things which are not spatial

Also, dang, I'm sorry I just noticed this branch was marked "draft" this whole time 😩 I've been pretty aggressively merging PRs as I see them these days 😅 I hope I didn't mess you up too much by modifying it and merging it this morning...

I'll still merge this now (because my edits expanded the scope a bit beyond vector fields) so that future PRs that refine this behavior can be small and easier to work with.

Thanks again for bringing this new plot type to ScottPlot5! 🚀

Magnitude is actually what I named it originally but I realized some of our other classes used Distance so I tried to be consistent. And then I learned Vector2 uses Length so I guess consistency is going to be hard.

I think the main thing that's missing is in the plottable factory, I don't think it automatically assigns a colour to the vector field (so it will be black by default). I don't think we should release a new version without that, but fortunately that's a 2 minute fix.

I also wonder if the legend should have a little arrow (right now it's just a line, which isn't great). As for all the colourmap stuff, that would be cool and probably pretty easy, but maybe not essential.

Good points! Thanks for your feedback.

Now that you mention it, I can see multiple sides to this. Since the RootedCoordinateVector and RootedPixelVector both have a unit baked in (coordinates and pixels), perhaps distance or length makes sense over magnitude.
