@arikfr Please lmk if I'm on the right direction and feel free to share your ideas. Thank you!

[arikfr]

We should have only two options:

1. To the right of the chart with auto behavior like today. I don't see why the user would want it otherwise.
2. To the bottom of the chart.

[kravets-levko]

I also experimented with other options, like placing legend above the plot, but that wasn't easy to implement (conflicted with modebar), so I abandoned this idea.

[arikfr]

Is it easy to add an option of "inside the chart"? (regardless of whether it's overlapping or not)

[arikfr]

Just a change to the option names to make them friendlier to users. Up to you if you want to change the naming in code.

Yes, it's possible. We can even choose anchors (all four corners). Would you like to see how it looks like?

Also, WDYT about moving "Show legend" checkbox to dropdown option ("Hide legend" or whatever) - to make UI less crowded?

I think it's a good idea.

If it's a small effort, then yes - let's do it. But maybe finish this one (with the "hide" in side the same dropdown) and try the new options in a separate PR? Then it will be easier to drop it if we don't like it.

[kravets-levko]

Okay, I'll move the checkbox to dropdown tomorrow morning (and add spelling fixes you suggested) and we'll finalize work on this PR. Then I'll prepare PR with more options.
