This sample demonstrates get jqChart image data URL with .jqChart('toDataURL', mimetype) method.

The jqChart can export its image to a data URL (e.g., data:image/png;base64,iVBORw0KGg...). This data may then be rendered in the browser, which could then be saved.

For detailed implementation, please take a look at the Aspx code tab.
