Highcharts工具提示x轴字体大小

Question

from the highcharts api it says we can edit the fontsize in the tooltip, however, this only edits the values and not the x axis label.

Is there a way to increase the size of the Tuesday, May 17... etc as well? ie the x axis label?

Editing the real xaxis label did not work.

Thanks! :)

For custom tooltips formatting, you can use the formatter property to pass a function which returns your custom html.

tooltip: {
        formatter: function () {
            return 'The value for <b>' + this.x +
                '</b> is <b>' + this.y + '</b>';
        }
    }, 
useHTML: true
