Hiding overlapping labels

[#1]

How do I script in JSL the preference that I don't want to hide overlapping labels, please?  If possible I'd like the preference to relate only to a specific chart I've created within the Graph Builder, but I'll settle for a general preference if isn't possible.

I've found the reference to "Hide Overlapping Labels" within the Preferences section of the Scripting Index, but the example doesn't seem to work. I note that the example actually says:

Preferences[1] << Set( Hide Overlap Labels( 0 ) );

and I'm guessing this is probably a typo, but correcting it to

Preferences[1] << Set( Hide Overlapping Labels( 0 ) );
show preferences();

 doesn't seem to work either, although the preference does now appear in the list, and the relevant check box has changed its setting when "Preferences" is invoked from the File menu. Clicking on the "Apply" button of the Preferences window seems to force the required change to be acted upon, but I'm trying to do this from a script.

Many thanks.

I have always used this JSL syntax to change a preference.

preferences( Hide Overlapping Labels(0|1) );

Hi - I've realised what the problem was: either syntax works, but the chart needs to be redisplayed (e.g. "gb << reshow") after amending the preference for the change actually to take effect.  Having said that, it looks as though resetting Hide Overlapping Labels( 1 ) after forcing all of the labels to be displayed doesn't actually do anything unless the chart is resized (even if the size is exactly the same as originally) - but that can be easily accommodated by doing it via a little function like this:

	OverlappingLabels = function({myChart, YesNo}, {default local},
		// myChart is the chart I'm modifying; YesNo is either 0 or 1;
		preferences( Hide Overlapping Labels(YesNo));
		sizeList = (myChart << get size);
		myChart << Size( sizeList[1], sizeList[2] )
	);

Many thanks.

Somehow it isn't working in JMP 15 even when you run it from Scripting Index:

What am I doing wrong?

Ok, it's Overlap vs. Overlapping.
And still I don't see any effect on my charts.
