Adding a line to a 3-D scatterplot

jennifer_n_blak

Hello!  

 

I have created a lovely 3-D scatterplot and am trying to add some things that will help interpretation of the points.

 

1. I would like to add a line connect the 0,0,0 vertex to the 1,1,1 vertex (a diagonal line from corner to corner through the middle).  There are very few points along this line, so using the contour options hasn't been working.

2. I would like to add a 2-tone gradient of background color to the walls so that it ranges from 1 shade on one end at 0, to a different shade at 1.

3. I would like to export this in its spinning glory.  A post from 2014 says this is not possible, but hopefully that has been remedied by now?

 

Point 1 and 3 are the most important.  I am interested in a non-scripting solution.  Thanks for your assistance!

There really haven't been any JSL upgrades to the 3D Scatterplot Platform, however, I believe the following technique will work, and I believe that it actually was available in 2014.  What I do to create the following display

is to create a new column that only has a value for the 2 rows that I want to draw a line between, and then I use

the Connect Points,  grouped by the new column, and it draws a line just between those 2 points.  Below is a sample script

Names Default To Here( 1 );
dt = New Table( "The Line",
	Add Rows( 40 ),
	New Column( "age",
		Numeric,
		"Ordinal",
		Format( "Fixed Dec", 5, 0 ),
		Set Values(
			[12, 12, 12, 13, 13, 13, 12, 12, 13, 16, 14, 13, 12, 12, 14, 14, 15, 15, 17, 14, 14,
			13, 14, 14, 14, 15, 13, 15, 16, 14, 14, 15, 15, 12, 15, 14, 16, 17, 14, 17]
		)
	),
	New Column( "height",
		Numeric,
		"Continuous",
		Format( "Fixed Dec", 5, 0 ),
		Set Values(
			[51, 52, 55, 56, 58, 59, 59, 60, 60, 60, 61, 61, 61, 61, 62, 62, 62, 62, 62, 63, 63,
			63, 64, 64, 64, 64, 65, 65, 65, 65, 65, 66, 66, 66, 67, 68, 68, 68, 69, 70]
		)
	),
	New Column( "weight",
		Numeric,
		"Continuous",
		Format( "Fixed Dec", 5, 0 ),
		Set Values(
			[79, 64, 74, 67, 95, 79, 95, 84, 112, 115, 81, 107, 123, 128, 85, 91, 92, 104, 116,
			84, 93, 105, 92, 99, 99, 112, 98, 111, 112, 119, 142, 105, 106, 145, 128, 112, 128,
			134, 113, 172]
		)
	),
	New Column( "Grouping",
		Character,
		"Nominal",
		Set Values(
			{"", "Line", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "",
			"", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "Line"}
		)
	)
);

dt << Scatterplot 3D(
	Y( :age, :height, :weight ),
	Connect Points( 1, :Grouping ),
	Frame3D(
		Set Grab Handles( 0 ),
		Set Rotation( -22.7391193234154, 33.6106458355737, 86.1083668103014 ),
		Set Marker Quality( 0.3875 ),
		Set Marker Scale( 1.21375 )
	)
);
