highcharts usehtml

Highcharts has a feature called "useHTML" that allows you to use HTML code to create custom labels, tooltips, and other elements in your charts. Here's an example:

Highcharts.chart('container', {
    title: {
        useHTML: true,
        text: '<span style="color:red">My Chart Title</span>'
    },
    xAxis: {
        categories: ['Apples', 'Oranges', 'Bananas']
    },
    yAxis: {
        title: {
            useHTML: true,
            text: '<span style="color:green">Number of Fruits</span>'
        }
    },
    series: [{
        name: 'John',
        data: [5, 3, 4]
    }, {
        name: 'Jane',
        data: [2, 2, 3]
    }]
});

In this example, we're using HTML code to style the chart title and the y-axis label. You can also use HTML to create custom tooltips and other chart elements. Just set the `useHTML` property to `true` and include your HTML code in the `text` property.
