Images or any other HTML in balloons / tool-tips
Balloons or tool-tips of our charts can accept any HTML. This means you can add images, tables, divs and format tool-tip content in any way you need. You can use custom fields from your data provider to create dynamic content of the balloon or even use your own custom method which would provide a tool-tip with a HTML code to be displayed.
