Hi Susanne,

Thank you for the logged feature request.

Indeed at the moment there doesn't seem to an option that allows setting a gradient background to the series area. Unfortunately there isn't a suitable workaround that I could suggest as well. Thus we will track the demand for this feature request and consider adding it to our future development plans.

In order to indicate some specific point in the chart the Note elements could be used:

In case further information is required for this case could I ask you to open a private support thread so that we can further clarify the requirement and try to suggest something else. Thank you.

Regards,
Svetlin
