Question

Is it possible to have 2 yAxis in a highstock chart from highcharts one on the left and another on the right ?

Thanks

Answer 1

A very simple example:
First you have to create your new yAxis and set it’s position.

{
    title: {
        text: 'Other data panel'
    },
    top: 300,
    height: 100,
    offset: 0,
    lineWidth: 2,
    opposite: true
}

Then, when you create your serie you in what yAxis it will be placed.

{
    type: 'column',
    name: 'Other',
    data: otherData,
    yAxis: 2,
    dataGrouping: {
        units: groupingUnits
    }
}

You can see it working here.
