[Feature Request] Addition of hover mode button to ModeBar

[bvenn]

Description

I cannot find an option to activate the mode bar button for multihover.

Known workarounds

You easily could set the hover mode in the ChartLayout chart |> Chart.withLayout(Layout.init(HoverMode=HoverMode.X)), but the activation of the button would be beneficial for exploratory analyses.

Solution

Addition of hovermode within the ModeBarButton .

	Chart.Point([1,2])
	Chart.Point([1,2])

|> Chart.Combine
|> Chart.withConfig(Config.init(ModeBarButtonsToAdd=[ModeBarButton.HoverMode]))
|> Chart.show
