How can change a black solid horizontal line to a black dashed line and change the transparency to 0.5

Thanks!

    Pen Color("black");
    Line({:test1[i] - bb, :test2[i]}, {:test1[i] + bb + 500 * (2 * bb), :test2[i]});

It didn't work

Pen Color( "black" );
seg = Line( {:test1[i] - bb, :test2[i]}, {:test1[i] + bb + 500 * (2 * bb), :test2[i]} );
seg << Set Line Style( "Dotted" );
seg << Set Transparency( .3 );

The setting of line style is easy. I am not seeing how to set the transparency for the line.

names default to here(1);
dt = new table("example",
	new column("test1",values([5])),
	new column("test2",values([10]))
);
bb=1;
i=1;
nw=new window("test",
	gb=graph box(
		Pen Color("black");
		line style("dashed");
		Line( {:test1[i] - bb, :test2[i]}, {:test1[i] + bb + 500 * (2 * bb), :test2[i]} );
	)
);

The line does not seem to have any segments that would allow for changing the transparency. Maybe some other member has a solution.

Thank Jim!

I try this

    Pen Color("black");
    Line({:test1[i] - bb, :test2[i]}, {:test1[i] + bb + 500 * (2 * bb), :test2[i]}  ,{ Line Style( "Dotted" ) , Transparency( 0.5 ) });
