Yes you are right that my request is how to put code in HTML Display to show the chart on page. Maybe my last demo project is not match with what we want, just updated to a new one as attched.
1. When put the chart.html file in root folder of project, and use iframe Tag to show chart, it works. but with refresh issue, use the Refresh element still have prolem of show new chart file (the refresh don't work maybe due too cookie or other problems, maybe it is not be able to refersh new src file, new file of chart.html).
2. In new project we put the code to both a Text Display (check code correct or not) and HTML Display (show chart) as you can run it on your broswer. But not be able to show chart, this is what we wanted (we have put script in head and one script in HTML from template which put data into body script).
3. You can open the chart.html with any broswer to verify html code, no any problem to show chart.
