ZingChart: How to add an anchor tag to chart title
In order to add an URL click ability or anchor tag to the chart title, there are two attributes you must insert into the title object.
1. flat: false
(Flat false overlaps the click event listener for the below label)
2. url:' www.google.com'
The resulting title object would look something like this:
title: { text:'Title Click Test', flat:false, url: 'www.google.com', target: '_blank' }
