In 13.1, there is not 'out of the box' means to export or print the Clarity Gantt chart. Taking screen shots and pasting into your app is only option.
Print feature was delivered in 13.3.
Exporting to Excel, apparently, is still in queue. I can find discussions about this, but not an Idea.
Except for simple projects and allowing team members to have a Gantt view in the browser, seems that most customers are sticking with OWB and MSProject for the bulk of their work.
