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>',
