How do i add error bars in chart builder using a var as the error term

[#1]

I have a dataset with the mean and SD as columns of data and i want to make a simple line graph with error +/- SD.   This seem extraordinarily difficult if not impossible to do in JMP .. 

of couse it is not that simple .. i have several groups of Y +/- SD  using the same X ... but i would be happy to just get one simple set ...

appreciate any help ...   with all JMP can do this should be easy.   ie not require coding ..

thanks in advance

Could you provide example data and some sort example graph of what you want to do?

Edit:

This might give some ideas How to create custom error bars in Graph Builder

Thanks ... the instructions in the article seem to do what i want, but it sure is complicated. (create a line fraph with error bars).   I will give it a try one problem is my X axis is numeric.   This the article in the link you provided was from 2017.  Seems since then JMP would have added an error-bar option.   I finally make the graph in Excel, which it not my favorite graphing program.    In excel, it took me a while to figure how to jitter the data so the error bars would not overlap.  

I attached the graph i made in Excel.  You can see the jittered error bars at 0, 3 ..  in data set there was in the. form.  X Y1 SDY1 Y2 SDY2 Y3 SD Y3.  

I plotted in Excel by making 3 copies of the X axis ...  and then manually editing the corresponding X value to achieve the Jitter at 0, 3.      This is clearly brute-force ... but worked    

I attached the Excel sheet as well, if you want to play.   I would really like to be able to create a column in JMP  and tell JMP that COL2 is the Error for COL1.

Thanks for the response ......

While Graph Builder allows multiple variables in the Y role, they all share the same Interval variable. Here's what I was able to get in JMP after stacking the variables into two columns, one for data and one for SD, and then using the SD column in the Interval role. I used the Local Data Filter to only show the three measures on interest and used a duplicated/split axis instead of your left/right axes.

Hi,

Have you tried to assign your error column to the Interval variable in the Graph Builder window? 

Also, if you have asymmetrical errors, you can assign two columns to the Interval variable to define the upper and lower boundaries of the error range.

Sorry if this is too simplistic for your case.

Best,

One more note:

Your Xs, Ys, and SDs need to be stacked (i.e., one column for each X, Y, and SD)

As noted previously in the link from Xan, when you have more than one overlay variable the "jitter" is too large.  As Thierry mentioned you need to stack your data.  Here's an example with two Y variables. Done in JMP 18 Early Adopter, but will work in versions 14, 15 and 16 as well.

Here's the graph.  Note the too-large jitter.  If someone knows how to remove the jitter please let us know!

Here's the code.

dt = New Table( "Error Bar Demo", Add Rows( 12 ),
	New Column( "Interval", Numeric, "Continuous", Format( "Best", 12 ),
		Set Values( [1, 2, 3, 4, 5, 6, 1, 2, 3, 4, 5, 6] )),
	New Column( "Y", Numeric, "Continuous", Format( "Best", 12 ),

		Set Values( {"BTD", "BTD", "BTD", "BTD", "BTD", "BTD",

);

dt << Graph Builder(
	Show Control Panel( 0 ),
	Variables(
		X( :Interval ),
		Y( :Y ),
		Y( :LCL, Position( 1 ) ),
		Y( :UCL, Position( 1 ) ),
		Overlay( :Label )
	),
	Elements(
		Points( X, Y( 1 ), Legend( 15 ), Jitter( "None" ) ),
		Line( X, Y( 1 ), Legend( 17 ) ),
		Bar( X, Y( 2 ), Y( 3 ), Legend( 18 ), Bar Style( "Interval" ))
	),
	SendToReport(
		Dispatch( {}, "Interval", ScaleBox, {Label Row( Show Major Grid( 1 ) )} ),
		Dispatch( {}, "Y", ScaleBox, {Label Row( Show Major Grid( 1 ) )} )
	)
);

If you stack your data and follow Xan's directions you'll be able to do this without writing JSL.
