using RGB values in JSL scripts instead of color name or whatever this (--16741343) is

Hello,

I'm new to using a basic JSL script that was saved after building a bar chart graphic. Although I set RGB values to assign colors to bars in Graph Builder, the resulting JSL script gives me this:

Properties( 1, {Fill Color( "yellow" )} ),
Properties( 2, {Fill Color( -16741343 )} ),
Properties( 3, {Fill Color( -11075814 )} ),
Properties( 4, {Fill Color( -16755200 )} ),

Can I use RGB values in this script instead and if so, what's the syntax? I tried "yellow" for example which works fine, but {Fill Color( 255,255,0 )} - the yellow I really want - does not.

Is it possible to use your own colors, or do you have to use JMPs table of colors?

Thanks!

You need to use the RGB Color() function. The Scripting Index gives a nice example of using the RGB Color() function to convert from RGB to the JMP color,.

Names Default To Here( 1 );
New Window( "RGB Color Example", 
/* 1 through 16 are good */ 
	division = 6;
	blocks = division + 1;
	ysize = 400 / Sqrt( division );
	xsize = ysize * blocks;
	fract = 1 / division;
/* 100 is default axis range */
	yBlockSize = 100 / blocks;
	xBlockSize = 100 / (blocks * blocks);
	Graph(
		frameSize( xsize, ysize ),
		For( blue = 0, blue <= 1, blue += fract,
			For( red = 0, red <= 1, red += fract,
				For( green = 0, green <= 1,
					green += fract,
					y = red / fract * yBlockSize;
					x = green / fract * xBlockSize
					+blue / fract * xBlockSize * blocks;
/* here's the example */
					Fill Color(
						RGB Color( red, green, blue )
					);
					Rect(
						x,
						y,
						x + xBlockSize,
						y + yBlockSize,
						1
					);
				)
			)
		)
	);
);
