How it works

The AnyChart Stock component offers both end-user and developer, using the component, a very wide range of options for exporting charts in any format. A chart can be exported as a static image in the PNG or JPG format or as a PDF document with an embedded static image of the chart or a fully interactive functional chart, as user sees it on the page.

To view and use saved the document saved in this format, you would need to have Adobe Acrobat Reader or Adobe Acrobat Pro version 9.0 or higher installed on the local machine; also the local machine must have the flash player of version at least 9.0 installed.

This sample shows how to configure export settings and obtain base64 encoded content of the exported file using getInteractivePDFBase64Encoded function.

You can learn more about image export in Chart Exporting section and learn about PNG export settings in Interactive PDF Export Settings article.
