brush(data, options)

[Fil]

Support for optional data and options in the brush marks (brush, brushX, brushY).

• options (x, y, fx, fy) propagate as channel defaults to the reactive marks (inactive, context, focus), so you don't have to repeat them
• brushX(data) defaults the x option to identity (to support an array of numbers, or dates); similarly brushY(data) defaults y to identity; brush(data) assumes an array of pairs of [x, y] coordinates
• support for dataless brush(options), brushX(options), and brushY(options)
• the brush’s selection rect can be styled with the following options: fill, fillOpacity, stroke, strokeWidth, strokeOpacity
• when data is provided, the value of the plot the filtered subset in the value's data property
