How to "Label by Value" for overlay plots? Scripting Help

I am trying to script an overlay plot. I have everything I want except I can not figure how to add value labels for the line and bar graph. Here is the script I am working with:

obj_1=dt23<<Overlay Plot(X(:Work Week and Year),

  Y(:Average Meters per Lot, :Number of Lots),

  Y Scale(Left,Right),

  :Average Meters per Lot(Connect Points(1)),

  :Number of Lots(Needle(1),Overlay Marker( 0 )),

  Left Axis << {{Format( "Best", 9 ), Min( 0 ),

  Max( 300 ), Inc( 20 ), Minor Ticks( 0 ),Show Major Grid (1)}},

  Right Axis << {{Format( "Best", 9 ), Min( 0 ),

  Max( 150 ), Inc( 30 ),

  Minor Ticks( 0 )}});

obj_1<<Uniform Y Scale(0);

obj_1<<Show Labels(1);

obj_1<<Label By Value(1);

The graph it produces looks like this:

Hi jsuls,

Are you trying to set row labels?  If yes, try turning them on by sending your command to the data table rather than to the overlay plot.  A script may look something like this.

Names Default to Here(1);

bigClass = open("$SAMPLE_DATA/Big");

over1 = bigClass << Overlay Plot( Y( :height, :weight ), Y Scale( Left, Right ) );

Column(bigClass, "name") << label(1); // Set column label.

bigClass << Select Randomly(5) << Label(1) << Clear Select; // Turn on row labels.

I don't think <<Label by value is supported in Overlay Plot(). It is supported in Chart() and Graph Builder() for categorical x-axis. Chart seem not to support dual y-axes, but Graph Builder is very versatile and can produce a graph very close to your example.

Open("$SAMPLE_DATA/Big") << Graph Builder(

    Variables(X(:age), Y(:weight), Y(:height, Position(1), Side("Right"))),


        Points(X, Y(1), Legend(1), Summary Statistic("Mean")),

        Bar(X, Y(1), Legend(2), Bar Style("Needle"), Label("Label by Value")),

        Points(X, Y(2), Legend(4), Summary Statistic("Mean")),

        Line(X, Y(2), Legend(6))



        Dispatch({}, "weight", ScaleBox, {Max(300)}),

        Dispatch({}, "400", ScaleBox, {Legend Model(6, Properties(0, {Line Color(19)}))})
