Applying forecastDataPoints to a single series

[pursuitofloot]

Hi there, is it possible to apply forecastDataPoints to a single series?

I have a line chart with 4 series of data, but only 1 of them I want to style with the dotted lines to show it's forecast data. As this is not specifically mentioned in the docs as a feature, I figured I'd ask here in case it was achievable in some way.

Thanks in advance 🙏
