Reference line from axis to specific value

pprabhu — Fri, 06 Apr 2018 11:57:34 GMT

hi,

i am new user to JMP and I was using Graph Builder for for developing a graph. However, I could not have specific value for x axis and y axis.

Currently I have option to keep minimum Scale and maximum scale with a increment.

eg.: Minimum: 0

Maximum: 24

Increment: 5

Then axis will be 0, 5, 10, 15, 20 and 25.

But I want like below:

0, 1, 2, 3, 6, 9, 12, 18, 24.

Can someone help? Thanks.

You cannot specify individual tick mark values. You might be able to get the scale you want by using the Power scale. (Right click on axis and select Axis Settings, then click Linear at the top left and select Power.) It might take further adjustment of the minimum, maximum, and increment settings to get what you want.

Hi,

Thanks, that should help. However, I am not finding Power option. I am using JMP 12.1.0

It's there - I just checked: right click on the axis you want to change and select Axis Settings. The first option at the top left of the dialog is where you can change from the default linear scale to another scale. Power is one of the choices.

Unfortunately, I don't think this change gives you what you want.

Since you are new to JMP, I am reluctant to show you this option that might work for you.

JMP data table columns have multiple properties that can be set. Value Ordering that allows you to set the order of nominal axes instead of the default alphabetical order is probably the most used ( ex. Never, Seldom, Sometimes, Frequent, Always).

Another popular column property is Value Labels. This property can be set with a JMP script (JSL) or interactively.

Attached is a table with 2 columns x and y; and and an attached script called y vs. x. Use the inverted red triangle menu and select Run Script. It will create a GraphBuilder plot with only 1,2,3,6,9,12,18,24 labeled. But you will notice that the data table x values look strange.

You can select Column Info for x and uncheck use value labels. The graph will continue to have the limited labeling unless it is redrawn.

This is a method to create a custom graph axis that is good for generating the graph. I wouldn't use it for an interactive graph. This is the JSL syntax for the Value Labels. I set the X axis scale to be 0.5 to 24.5 with an increment of 1. Note the unwanted laebls are set to empty strings, and hence will not appear. You did not mention if you wanted these values to be equidistant, or linear spacing with limited labeling.

If your data only has your specified values (ex. a lifetime test, 1day 2, days, 3 days, etc.) another platform graph or a variability chart might be more useful. Interesting question.

:x << Value Labels(
			{1 = "1", 2 = "2", 3 = "3", 4 = "", 5 = "", 6 = "6", 7 = "", 8 = "", 9
			 = "9", 10 = "", 11 = "", 12 = "12", 13 = "", 14 = "", 15 = "", 16 = "",
			17 = "", 18 = "18", 19 = "", 20 = "", 21 = "", 22 = "", 23 = "", 24 =
			"24"}
		) << Use Value Labels( 1 );
