AnyChartStock JavaScript API
Prerequisites

How to use this sample?

Click any button to save exported chart in one of the available formats to your local PC.

How it works

The 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.

When exporting a chart to any format, the component takes care of the entire file generation process. That means that you do not need to implement the conversion on the server side. The component automatically generates a ready-for-service file on the client side, not adding any extra load to the server. The only place where the server side is used is the helper script, which allows the end-user to save the file generated by the component on the local computer.

On any button click simple one of the following function is called: exportAsPNG, exportAsJPG, exportAsPDF or exportAsInteractivePDF.

You can read more about the way the export is organized at: Export to a local computer article.
