Customizable Brush Events?

[spren9er]

When dealing with lots of data, brushing on brush events for interval1d and interval2d interactors can lead to lagging queries and sluggish UI:

brush_end_event.mov

In that case, switching to brushing only on end events would be better:

end_event.mov

My suggestion would be to introduce a new attribute brushEvent to intervalX, intervalY and intervalXY interactors, which is by default brush end, but could be changed to end.

Any other ideas?

That sounds reasonable to me. One question is if we want to expose these d3-specific event names, versus having a bit more abstraction via a boolean toggle (default false), which when true results in end events only. Are there any cases other than brush end and end that we might want to consider?

I agree, a boolean toggle would be sufficient and also be more user-friendly.
If I find some time, I'll implement this...
