API Reference

d3.swoopyDrag()

Creates a new swoopyDrag.

swoopyDrag.x([function])

Function called on each annotation object to determine its x position.

swoopyDrag.y([function])

Function called on each annotation object to determine its y position.

swoopyDraw.draggable([boolean])

Boolean. Pass true while adjusting annotations to enable dragging and add control points to paths.

swoopyDrag.annotations([array])

Array of objects representing annotations. The path in each annotations will have its d attribute set to the path property. The text element will contain the text property and be translated by textOffset.

swoopyDrag.on('drag', [function])

Called as the labels or paths are dragged.

swoopyDrag.bootstrap()

Creates a new swoopyBootstrap.

Usage:

var swoopyBootstrap = swoopyDrag.bootstrap()
  .scale({x: myXScale, y: myYScale})
  .sel(swoopySel)
  .labelAccessor(function(d, i) { return "Hello, world!" })
someD3Selection.call(swoopyBootstrap)

swoopyBootstrap.scale([object])

Set the scales for the bootstrap function to use.

Usage: swoopyBootstrap.scale({x: myXScale, y: myYScale})

swoopyBootstrap.sel([object])

Point bootstrap to the D3 selection you are using for annotations.

Usage: swoopyBootstrap.sel(swoopySel)

swoopyBootstrap.labelAccessor([function])

Pass in a function to set the label text.

Usage: swoopyBootstrap.labelAccessor(function(d, i) { return "Hello, world!" })

swoopyBootstrap.container([DOM Node])

Explicitly set the DOM node which will be used to determine the offset for mouse events. If you are setting transforms on the elements you want to annotate, you will likely need to use this or your annotations may show up in a place other than where you intended.

Usage: swoopyBootstrap.container(swoopySel.node())
