How to change the color of many histogram distributions?

AT — Tue, 13 Mar 2018 21:41:17 GMT

Hi,

I am plotting 64 histogram distributions and stack them together. I like to change the color of each histogram different. You can manually do this but how one can change this automatically?

I appreciate your help. Thanks

The Histogram Color is programatically available to JSL. You can fairly easily write a script to do this. Here is the result of just using Customize and then having the platform generate the script for the modification

Distribution(
	Stack( 1 ),
	Continuous Distribution(
		Column( :height ),
		Horizontal Layout( 1 ),
		Vertical( 0 )
	),
	Continuous Distribution(
		Column( :weight ),
		Horizontal Layout( 1 ),
		Vertical( 0 )
	),
	SendToReport(
		Dispatch(
			{"height"},
			"Distrib Histogram",
			FrameBox,
			{DispatchSeg(
				Hist Seg( 1 ),
				{Line Color( {108, 60, 65} ), Fill Color( "Medium Light Green" )}
			)}
		),
		Dispatch(
			{"weight"},
			"Distrib Histogram",
			FrameBox,
			{DispatchSeg(
				Hist Seg( 1 ),
				{Line Color( {108, 60, 65} ), Fill Color( "Red" )}
			)}
		)
	)
);

Thanks Jim. Does it mean I have to do this for 64 Histograms that I want to build and stack them together?

The simple answer is yes......however, using a For() loop and Substitution you can just loop through the 64 histograms you want and generate the necessary code
