Value Colors - same color for a block of values?

[#1]

When defining colors via value colors, is there an easy way to define the same color for a block of (e.g. 100) adjacent values?

I can select the block via Shift Click, but how to apply the color.

Selecting the respective rows and changing the color manually is no option because I want the rule to be applied dynamically after data changes.

Hi,

Considering your advanced level in this Discussion forum, I am unsure if this suggestion will help.

Have you considered creating a grouping formula (e.g., Quantiles) to which you could assign colors? 

If(
	:X <= Col Quantile( :X, 0.25 ), 1,
	Col Quantile( :X, 0.25 ) < :X <= Col Quantile( :X, 0.5 ), 2,
	Col Quantile( :X, 0.5 ) < :X <= Col Quantile( :X, 0.75 ), 3,
	4
);

// OR a classification based on Rank //

Round( (Col Rank( :X ) * 10) / N Rows(), 0 );

These are just workarounds.

Best,

TS

An auxiliary variable is a good idea, thanks :)

While playing around I found out that for long lists the values in a GraphBuiler plot don't match the values defined via Value Colors ( TS-00045154). According to Jmp support, this is a known issue and will be fixed in Jmp 18.

Workaround: define the colors via JSL:

dt = Open( "$SAMPLE_DATA/Aircraft Incidents.jmp" );
locs= AssociativeArray(dt:Location << get values) << get Keys;
myMax=N items(locs);
colorList = Transform Each({i},As List(Transpose(1::myMax)),
                Substitute(Expr(__a__ = __b__), Expr(__a__), locs[i], Expr(__b__), -15000000 +i)
);
dt:Location << delete property("Value Colors");
Eval(substitute(Expr(dt:Location << Set Property("Value Colors",__cols__)),Expr(__cols__),Name Expr(colorList)));

                Elements( Points( X ) )
