Bivariate Chart - how to connect data points?

djhanson — Sat, 02 Dec 2017 00:34:54 GMT

Can data points be connected in a Bivariate chart? (no fit of any kind, just a straight connection among consecutive points within each of overlaid groupings)

In this case, I am grouping by several items so that all groups display on a single bivariate chart. (so I'm attempting to connect each group's points together) thx, DJ

You could try using Graph Builder where there is the line graph option to connect the X,Y points. It sounds like you might want to only connect the points by groups, however. In that case, you could use Fit Y by X, and before selecting Fit every point, use the group by command to do it by whatever your grouping column is.

Traditonally the Overlay Plot option under graphs was designed to do this. It's still hanging in there on the Graph menu (only just!)

Or perhaps the new in JMP 13 Parallel Plots workflow embedded in Graph Builder? Not sure if this is what the original poster is after? Here's a link to the online JMP 13 documentation for the Graph Builder Parallel Plot capability:

Maybe you are after something like this?

Names default to here( 1 );

dt = Open( "$Sample_data/Big Class.jmp" );

dt << Graph Builder(
	Size( 403, 330 ),
	Show Control Panel( 0 ),
	Variables( X( :height ), Y( :weight ), Overlay( :sex ) ),
	Elements(
		Points( X, Y, Legend( 3 ) ),
		Line( X, Y, Legend( 5 ), Row order( 1 ) )
	),
	Local Data Filter(
		Add Filter(
			columns( :age ),
			Where( :age == 13 ),
			Display( :age, Size( 256, 144 ), List Display )
		)
	)
);

This is almost too easy, so I've presumed it isn't what you want, but have you tried Fit Each Value under the Flexible option under the red triangle menu?
