bonjour,

j'ai superposé 3 variables sur l'axe Y.

est-il possible d'ajouter un trait vertical pour relier le mini au maxi pour chaque identifiant de l'axe X ? Il faudrait qu'on puisse choisir la couleur, l'épaisseur et la transparence du trait vertical.

voir l'image avec un exemple dans le cercle.

cordialement

You could try using Range Error Bar

Or you could add Interval Bar chart and disable the "middle" value (this might require some extra calculations / columns)

And then there is of course scripting option using graphic script which is more complicated

Here is one possible example for scripted option

Names Default To Here(1);

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

dt << New Formula Column(Operation(Category("Aggregate"), "Minimum"), Columns(:height), Group By(:age));
dt << New Formula Column(Operation(Category("Aggregate"), "Maximum"), Columns(:height), Group By(:age));

gb = dt << Graph Builder(
	Size(525, 448),
	Show Control Panel(0),
	Variables(
		X(:age),
		Y(:height),
		Y(:"Maximum[height][age]"n, Position(1)),
		Y(:"Minimum[height][age]"n, Position(1))
	),
	Elements(Points(X, Y(1), Y(2), Y(3), Legend(3), Summary Statistic("Mean")))
);



segs = Report(gb)[FrameBox(1)] << Find Segs();
ys = [];
xs = {};
For Each({seg}, segs, 
	If(seg << Class Name == "MarkerSeg", 
		ys = ys |/ (seg << get y values)`;
		Insert Into(xs, seg << get x values);
	)
);

For Each({{ymin, ymax, x}}, Across(V Min(ys), V Max(ys), xs[1]), 
	Eval(EvalExpr(
		Report(gb)[FrameBox(1)] << Add Graphics Script(
			"Back",
			Pen Color("Purple");
			Pen Size(20);
			Transparency(0.2);
			V Line(Expr(x), Expr(ymin), Expr(ymax));
		);
	));
);

Write();

This "simple" example won't work with filters.

And then there is Marker Draw Expr where you can control the color and transparency from legend and width from the draw expression

Names Default To Here(1);

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

dt << New Formula Column(Operation(Category("Aggregate"), "Minimum"), Columns(:height), Group By(:age));
dt << New Formula Column(Operation(Category("Aggregate"), "Maximum"), Columns(:height), Group By(:age));

gb = dt << Graph Builder(
	Size(746, 818),
	Show Control Panel(0),
	Variables(
		X(:age),
		Y(:height),
		Y(:"Maximum[height][age]"n, Position(1)),
		Y(:"Minimum[height][age]"n, Position(1))
	),
	Elements(
		Points(X, Y(1), Y(2), Y(3), Legend(3), Summary Statistic("Mean")),
		Points(X, Y(1), Legend(4), Summary Statistic("Mean"))
	),
	Local Data Filter(Add Filter(columns(:age), Display(:age, N Items(6)))),
	SendToReport(
		Dispatch({}, "400", ScaleBox,
			{Legend Model(
				4,
				Properties(
					0,
					{Line Color(35), Transparency(0.2)},
					Item ID("Mean(height)", 1)
				)
			)}
		)
	)
);

frame = Report(gb)[FrameBox(1)];
seg = (frame << FindSeg(Marker Seg(4)));
seg << Set Marker Draw Expr(
	Function({this seg, this row, x, y, size, row state},
		size = 0.1;
		Rect(
			x - size,
			:"Maximum[height][age]"n[this row], 
			x + size,
			:"Minimum[height][age]"n[this row],
			1
		);
	);
);
