allowHTML property
Experimental setting to allow 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.
