    // an axis: series[n] => yaxis[n]. This needs to be retained for compatibility.
    // But we introduce an alternative that explicitly configures yaxis elements
    // with the series that will be referenced to them (seriesName: []). This
    // only requires including the yaxis elements that will be seen on the chart.
    // Old way:
    // ya: s
    // 0: 0
    // 1: 1
    // 2: 1
    // 3: 1
    // 4: 1

    // the contributing series. This is not particularly intuitive.
    // New way:
    // ya: s
    // 0: [0]
    // 1: [1,2,3,4]
    // If the chart is stacked, it can be assumed that any axis with multiple
    // series is stacked.
    //
    // If this is an old chart and we are being backward compatible, it will be
    // expected that each series is associated with it's corresponding yaxis
    // through their indices, one-to-one.
    // If yaxis.seriesName matches series.name, we have indices yi and si.
    // A name match where yi != si is interpretted as yaxis[yi] and yaxis[si]
