Answer 1

We can hide Yaxis label without hiding the y-Axis without hiding the series by returning the empty string as follows:

yAxis: {
       title: '',
       labels: {
                formatter: function() {
                    return '';
                },
                style: {
                    color: '#4572A7'
                }
        }

},
