HI there, two questions: after purchasing a license do we have to show the 'highcharts.com' watermark on the charts?
And more importantly: I want a 'last updated' field on my charts that shows when the underlying data was last updated. This info will be provided in the data. Ideally I would like this info to be displayed exactly as the 'highcharts.com' watermark, same style, same position, it would just be perfect. Can you show me how to implement a custom text box (I guess?) that has the same properties? Or is there another easy way? I can't use figure (sub-)title or caption because they are needed for the chart itself.
Thank you so much, as always!
