Make 'smoother' lines transparent in Graph Builder?

Question

As the subject says, is there any way to make the "smoother" lines in Graph Builder transparent? Right-click > Graph > Transparency... only affects the points, not the lines.

I would like to be able to build a graph with hundreds of lines overlaid, and make those lines transparent so that they are not overplotted and it's easier to see the "distribution" of trends.

Likewise, is there a way to change the line width/style of all the lines at once? You can change individual lines in the Customize... window, but that is infeasible for hundreds or thousands of lines.

I am currently using JMP 13.2.

Thanks!

Erik,

Regarding widening the lines all at once, try this, assuming the reference variable for your graph builder is called gb

_xx = gb << Xpath("//LineSeg");

_xx << Line Width(3);

One method to view one line (one overlay variable) at a time is to add a Local Data Filter.  The only problem I saw was the line and symbol colors are not maintained in the few examples I tried.

Attached is a script from Chapter 7 of our book, demonstrating interactive graphs.  This script enhances a graphbuilder plot that has a many level overlay variable,  U. S. states.  The enhancements include:

* a scrollable legend, so the legend box is not taller than the graph, and
* a mousebox, that hides all but the state of interest; when the mouse is hovered near a state's name in the legend, only that state's curve/points are displayed.

I modified the book example with the JSL shown above, that is, it is modified to have wide lines.

You can right click on the smoother legend and select Transparency, to change it
