Allow alpha or series as option for graph.datalabel

[mamo]

Dear Eviews team.
I use Eivews 13 October 17 2022 build
Kindly consider to expand the datalabel command for graph objects so that the contents of a series or of an alpha series can be made shown as data labels (x.datalabel point(all) label(myalphaseries))
Best, mamo
