Should it be possible to filter the _tip_ mark when creating it implicitly via the _tip_ option on a different mark?

[mwaibel-go]

Consider this plot definition:

Plot.dot([[1, 1]], {tip: {filter: () => false}}).plot()

The tip object above is passed to to the Tip mark constructor, which has no documented filter option. So we cannot actually disable tips based on the displayed data (or generally). I’m wondering if we should.

My actual use case involves the need to access the (transformed and binned) data for a mark on hover. I’m trying to avoid duplicating these computations when using the Pointer mark. I was working off of the Histogram selection example, but I don’t need the tip mark.

The same behaviour can be achieved by overriding the render function:

Plot.dot([[1, 1]], {tip: {render: () => null}}).plot()
