How can I plot multiple prognosis versions in one plot ("bad hair day graph")?

[Qlikders]

Hi,

I have a model that makes new prognosis of various parameters every quarter of a year (see list of prognosis versions below). I would like to plot the prognosis versions that are selected by user together with the real data like shown in the lower figure. This should result in one line per selection in the list. When a new prognosis version occurs (2020-03-31) it should automatically appear on the list when reloading the data, and be possible to select. Does anybody have an idea if this can be done? Any help is appreciated.

Thanks

Anders
