Value axis

The value axis show the scale chart values.

Chart can have any number of value axis. Each value axis is identified by a string identifier.

To define value axis, use valueAxis section in settings:

    valueAxis: {
      "myAxis": {
        position:"outside",
        side:"left",
        size: 45,
        style:{ valueLabel: {font: "11px Arial"}},
        zeroLine: "center"
      },
      "mySecondAxis":{
        ...
      }
    }

By default the chart has a single value axis named "default" and all series are by default bound to it.

To bind a series to value axis, use series.valueAxis property:

    series: [
      {
         ...
         valueAxis: "myAxis"
         ..
      }
    ]
