Thanks for the replies! Gonna go with this one, because this saves a few clicks when inserting individual graphs somewhere!
I'm actually running a jsl loop like this to put a bunch of images into one report (with some custom axis autoscaling and a pptx export as well):
win = New Window( "Window", Outline Box( "Graphs", hb = V List Box() ) );
For( i = 9, i <= N Cols( dt ), i++,
gb = Graph Builder( Variables( X( :Column1 ), Y( Eval( i ) ), overlay( :Group ) ) );
hb << Append( Report( gb ) << child );
hb << append( Page Break Box() );
gb << Save Picture( "path" || strTitle || ".emf", emf );
gb << close window;
);
