default:

      formatLabel (bar, formatX, formatY) {
        return [
          'x: ' + formatX(bar.xv),
          'y: ' + formatY(bar.yv)
        ]

• bars: Boolean : show bars | Object:

  • gradient: Boolean | Object : { sroke:Boolean, fill:Boolean }

• curve: Boolean | Object:

  • type: String | Function

    • String, name of d3 curve Types ex: 'linearClosed' or 'curveLinearClosed' (default: MonotoneX) see d3-shape#curves

    • Fuction: custom curve function

• curveBack: render another curve, with same settings as default.

• marks: Boolean | Object: {type: point | square style:{ fill , stroke }, size }

d object

• xv: original x value
• yv: original y value
• x: computed chart x value
• y: computed chart y value
• color: computed chart color
• percentX: percent of x
• percentY: percent of y
• w: computed bar width,
• d: original data

Events

• barClick: fired on click/touch bar, emits bar,event
