HOWTO: Turning a label into a link

Prior to version 6.18 doing this involved a significant effort and a not-insubstantial amount of code to achieve. However since version 6.18 was made available it has become as simple as adding an anchor tag (<a>) around your label. The target attribute is also supported so you can stipulate that the link opens in a new window if you want it to. As well as the labels you can also give links in the title, subtitle, any custom text, key labels etc. Here's some sample code for a Pie chart that uses links in the labels:

>script<
    new RGraph.SVG.Pie({
        id: 'chart-container',
        data: [4,8,6,5,3,4,6,8],
        options: {
            labels:[
                    '<a href="https://www.google.com#q=richard" target="_blank">Richard</a>',
                    '<a href="https://www.google.com#q=jimmy" target="_blank">Jimmy</a>',
                    '<a href="https://www.google.com#q=apollo" target="_blank">Apollo</a>',
                    '<a href="https://www.google.com#q=davey" target="_blank">Davey</a>',
                    '<a href="https://www.google.com#q=craig" target="_blank">Craig</a>',
                    '<a href="https://www.google.com#q=alex" target="_blank">Alex</a>',
                    '<a href="https://www.google.com#q=terry" target="_blank">Terry</a>',
                    '<a href="https://www.google.com#q=june" target="_blank">June</a>'
                ],
                title: '<a href="https://www.google.com#q=scores" target="_blank">User scores</a>',
                titleOffsety: -9
        }
    }).draw();
>/script<
