Changing color of bar graph

hxnduke

Hi all,

I have a quick question regarding changing legend color. Below is the script that I copied directly from my data table. I understand the number within "Fill Color" specifies what color I want for the respective group shown in Item ID. However, can anyone tell me what number "28" means and what number "8/7/6" here mean. I tried searching through their syntax document but couldn't find anything on this.

Thank you!

{Legend Model(
				28,
				Properties( 8, {Fill Color( 35 )}, Item ID( "B1 D14", 1 ) ),
				Properties( 7, {Fill Color( 36 )}, Item ID( "B4 D14", 1 ) ),
				Properties( 6, {Fill Color( 37 )}, Item ID( "C4 D14", 1 ) )		
			)}

I fully agre4e with mark, if by any chance possible avoid it to modify "send to report" parts as it will be less robust and hard to debug.

That is what I would think about the behaviour you see in your code snippet:

Properties( 3, {Fill Color( 3 )}, Item ID( "A", 1 ) ),
Properties( 2, {Fill Color( 5 )}, Item ID( "B", 1 ) ),
Properties( 1, {Fill Color( 4 )}, Item ID( "C", 1 ) ),
Properties( 0, {Fill Color( 8 )}, Item ID( "D", 1 ) )


// compared to 
Properties( 1, {Fill Color( 3 )}, Item ID( "A", 1 ) ),
Properties( 2, {Fill Color( 5 )}, Item ID( "B", 1 ) ),
Properties( 3, {Fill Color( 4 )}, Item ID( "C", 1 ) ),
Properties( 4, {Fill Color( 8 )}, Item ID( "D", 1 ) )

In the properties call you have always the "Item ID" included. This is a clear identifier which is stronger than the order at the beginning. I'm pretty sure if you remove the identifier, you will see a change in the color

Properties( 3, {Fill Color( 3 )} ),
Properties( 2, {Fill Color( 5 )}),
Properties( 1, {Fill Color( 4 )}),
Properties( 0, {Fill Color( 8 )})

// compared to 

Properties( 0, {Fill Color( 3 )}, Item ID( "A", 1 ) ),
Properties( 1, {Fill Color( 5 )}, Item ID( "B", 1 ) ),
Properties( 2, {Fill Color( 4 )}, Item ID( "C", 1 ) ),
Properties( 3, {Fill Color( 8 )}, Item ID( "D", 1 ) )

Once more: Avoid playing with these if possible. Just one change in a variable reducing the levels might have an impact.

Check out this link, 35 is the 4th item in the 'medium light' series, so it is a medium-light red.

The 8,7,6 numbers should refer to the position within the legend.

@ih

The 8,7,6 numbers should refer to the position within the legend.

Did you mean the order within the legend? Because if I shuffle the "0,1,2,3" numbers in the script below in whichever way, I would still get the same order within my legend.

New Table( "Untitled 119",
	Add Rows( 4 ),
	New Script(
		"Value vs. Group",
		Graph Builder(
			Size( 534, 463 ),
			Show Control Panel( 0 ),
			Variables( X( :Group ), Y( :Value ), Overlay( :Group ) ),
			Elements( Bar( X, Y, Legend( 6 ) ) ),
			SendToReport(
				Dispatch(
					{},
					"400",
					ScaleBox,
					{Legend Model(
						6,
						Properties( 0, {Fill Color( 3 )}, Item ID( "A", 1 ) ),
						Properties( 1, {Fill Color( 5 )}, Item ID( "B", 1 ) ),
						Properties( 2, {Fill Color( 4 )}, Item ID( "C", 1 ) ),
						Properties( 3, {Fill Color( 8 )}, Item ID( "D", 1 ) )
					)}
				)
			)
		)
	),
	New Column( "Group", Character, "Nominal", Set Selected ),
	New Column( "Value", Numeric, "Continuous", Format( "Best", 12 ), Set Selected )
)

Please see picture below as example. Picture on the left was achieved by running the script I attached on the previous reply. Picture on the right was done by reversing the order to:

Properties( 3, {Fill Color( 3 )}, Item ID( "A", 1 ) ),
						Properties( 2, {Fill Color( 5 )}, Item ID( "B", 1 ) ),
						Properties( 1, {Fill Color( 4 )}, Item ID( "C", 1 ) ),
						Properties( 0, {Fill Color( 8 )}, Item ID( "D", 1 ) )

Unfortunately I don't fully understand the interaction between Base and Properties in this context, and so far haven't found a good reference explaining the difference. Hopefully someone else can chime in here.

As has been stated many times in many discussions such as this, the Send To Report() mechanism is not intended for you. Send To Report() was devised as a way for JMP to save customizations to the report layer of a platform. Of course, you can use it, but then you usually run into such issues and a lot of confusion. You can avoid this mess entirely by sending the appropriate message to the platform instead. For example, I can change the color theme for the bars without using Send to Report() like this illustration:

Names Default to Here( 1 );

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

gb = dt << Graph Builder(
	Size( 534, 448 ),
	Show Control Panel( 0 ),
	Variables( X( :age ), Y( :weight ), Overlay( :age ) ),
	Elements( Bar( X, Y, Legend( 8 ) ) )
);

Wait( 2 );

gb << Categorical Color Theme( "Pastel" );
