I would also like to see this functionality and dont like the prospect of paying for an API to then have to work out how to make the changes I need.
I am surprised that no one has added this to highcharts because it seems to be a common requirement and I have spent 2 days researching available API's (free and paid) and none of them supports this functionality.
I would have thought it would be good to be the only API that does offer this functionality..Paul supported this idea ·
