Export to PDF

You could easily export the RadHtmlChart control with the RadClientExportManager to PDF (as shown in the demo) and to an image. You can also use the skin chooser to change the appearance of the component and export the new appearance.

Known Limitations:
The exporting functionality does not work out of the box in IE version 9 and lower and Safari, because RadClientExportManager relies on the File API in order to work and the mentioned browsers do not support File API. You can use a proxy that streams the file to the end user in these scenarios, as explained in the IE9 and Safari Compatibility help article.
