Graph builder with separate overlay, color and marker

[#1]

I am trying to use JSL to construct a plot similar to the one shown above. My attempt is below. Where I am stuck is that I don't want the marker legend to use the overlay variable, but to use lgd2. The solution needs to work for various number of categories for "lgd1" and "lgd2".

dt = New Table( "example",
	Add Rows( 18 ),
	Set Header Height( 60 ),
	New Column( "lgd1",
		Character,
		"Nominal",
		Set Values(
			{"A", "A", "A", "A", "A", "A", "B", "B", "B", "B", "B", "B", "C", "C",
			"C", "C", "C", "C"}
		),
		Set Display Width( 63 )
	),
	New Column( "lgd2",
		Numeric,
		"Nominal",
		Format( "Best", 12 ),
		Set Values( [1, 1, 1, 2, 2, 2, 1, 1, 1, 2, 2, 2, 1, 1, 1, 2, 2, 2] )
	),
	New Column( "value",
		Numeric,
		"Continuous",
		Format( "Best", 12 ),
		Set Values( [1, 1, 2, 1.5, 1.5, 2, 2, 2, 3, 2, 4, 3, 4, 4.5, 5, 4, 6, 5.5] )
	),
	New Column( "X",
		Numeric,
		"Continuous",
		Format( "Best", 12 ),
		Set Values( [1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3] )
	),
	New Column( "Group",
		Character,
		"Nominal",
		Set Values(
			{"A-1", "A-1", "A-1", "A-2", "A-2", "A-2", "B-1", "B-1", "B-1", "B-2",
			"B-2", "B-2", "C-1", "C-1", "C-1", "C-2", "C-2", "C-2"}
		)
	)
);


DT << Graph Builder(
	Size( 500, 500 ),
	Show Control Panel( 0 ),
	Fit to Window( "Off" ),
	Variables( X( :X ), Y( :value ), Overlay( :Group ), Color( :lgd1 ) ),
	Elements( Line( X, Y, Legend( 1 ) ), Points( X, Y, Legend( 2 ) ) ),
	SendToReport(
		Dispatch(
			{},
			"400",
			ScaleBox,
			{Legend Model(
				1,
				Properties( 0, {Marker Size( 5 )}, Item ID( "A", 1 ) ),
				Properties( 1, {Marker Size( 5 )}, Item ID( "B", 1 ) )
			), Legend Model(
				2,
				Properties( 3, {Marker Size( 5 )}, Item ID( "A-1", 1 ) ),
				Properties( 4, {Marker Size( 5 )}, Item ID( "A-2", 1 ) ),
				Properties(
					5,
					{Marker( "Circle" ), Marker Size( 5 )},
					Item ID( "B-1", 1 )
				),
				Properties(
					6,
					{Marker( "Plus" ), Marker Size( 5 )},
					Item ID( "B-2", 1 )
				),
				Properties(
					7,
					{Marker( "Circle" ), Marker Size( 5 )},
					Item ID( "C-1", 1 )
				),
				Properties(
					8,
					{Marker( "Plus" ), Marker Size( 5 )},
					Item ID( "C-2", 1 )
				)
			)}
		),
		Dispatch(
			{},
			"400",
			LegendBox,
			{Legend Position( {1, [0, 1, 2], 2, [-1, -1, -1, 3, 4, 5, 6, 7, 8]} ),
			Position( {0, 1, 2, -1, -1, -1, 3, 4, 5, 6, 7, 8} )}
		)
	)
);

Hi, 

Just a quick note that may (perhaps) meet your requirements if you do not mind a bit of manual preparation:

1. Create 2 new columns by splitting Group column (Column > Text to Column  > Separator = "-".
2. If you want, rename the column as CLASS and SUBCLASS, respectively
3. Assign Symbols to each row based on the SUBCLASS column (No Color, Symbols = Standard)
4. Build your plot with Overlay = Group, and Color as CLASS
5. Under the Points menu, deactivate the Overlay option (as shown below)

There is another manual option where you will not need to assign the Markers and switch-off the Overlay under Points: in the Preferences > Graphs > Graph Marker Theme > Paired will yield something similar to what you may need.

Best,

Thanks, @Thierry_S . I've edited my original post to include more details on the required solution.
