      • setAccessibility

        public void setAccessibility​(ExportingAccessibility accessibility)
        Accessibility options for the exporting menu.

        10.2.1.0

      • isAllowHTML

        public boolean isAllowHTML()
        Experimental setting. Returns whether allows HTML inside the chart (added through the useHTML options), directly in the exported image. This allows you to preserve complicated HTML structures like tables or bi-directional text in exported charts. Disclaimer: The HTML is rendered in a foreignObject tag in the generated SVG. The official export server is based on PhantomJS, which supports this, but other SVG clients, like Batik, does not support it. This also applies to downloaded SVG that you want to open in a desktop client.

        Default: false

        Since:
        7.2.1.0

      • setChartOptions

        public <V> void setChartOptions​(Map<String,​V> chartOptions)
        Sets additional chart options to be merged into an exported chart. For example, the exported chart can be given a specific width and height, or a printer-friendly color scheme.

        Defaults to null.

        For example, to export a chart with different size from the displaying chart, 

         
 Map<String, Number> options = new HashMap<String, Number>();
 options.put("width", 350);
 options.put("height", 600);
 chart.getExporting().setChartOptions(options);

        To export a chart with different background image from the displaying chart, 

         
 Map<String, String> options = new HashMap<String, String>();
 options.put("plotBackgroundImage", "http://www.example.com/sky.png");
 chart.getExporting().setChartOptions(options);

        To export a chart with both different background image and size from the displaying chart, 

         
 Map<String, Object> options = new HashMap<String, Object>();
 options.put("width", 350);
 options.put("height", 600);
 options.put("plotBackgroundImage", "http://www.example.com/sky.png");
 chart.getExporting().setChartOptions(options);

        Do notice the different type signature in the options map declaration.
