Add footnote textbox immediately below chart.
I have several charts for which I need both subtitles and footnotes to clarify/explain the presentation of data (and I always use credits). When displaying on the web it is easy enough to add a paragraph under the chart, however I also need this footnote when exporting the chart. I would envision a simple text box above the credits section.
There is a similar suggestion that was closed with the suggestion to use subtitles ( http://jsfiddle.net/sGv32/5/ ), but this suggestion will obviously not work if subtitles are already being used. Also, in Chrome, the chart tries to display below the footnote, and is completely flattened out.
Here’s an example of how to add a responsive and exportable text box programmatically: http://jsfiddle.net/highcharts/WwPFN/
I'm 4 or 5 years late to the party but it appears this is still an issue. Torstein, thanks for the example but what would be more useful would be the equivalent of a text field that behaved similar to a title or subtitle but *under* the chart. It would span the width the chart itself and, most importantly, the chart would make space for it as is the case for the title and subtitle.

I too would enjoy this feature. I've tried my hand at hacking it in, but have problems when it comes to the responsive side of the charts. Have a hard time myself getting the text to flow properly when window screen size is changed.
A text area below the legend would be pefect that gets included with the chart on print or image export.
