How to show the actual range in the level values in Graph Builder?

[#1]

Hi,

In the attached plot, the property of column "ChannelNumber" is Numeric/Continuous. I found it confusing in the grouped values at the top. "0-4" actually includes 0-3, as shown at the bottom; "4-8" actualy includes 4-7. It seems the range at the top always has overlapping values between adjacent levels. What can I do to make this overlap go away (i.e. I want it to show "0-3", "4-7","8-11" at the top)? Thank you very much...

Hi Jane

增加一个新的列，将你原先的信道归纳到这3个分类里。（0~3，4~7，8~11）

用新增的列作为X group即可实现你的需求。

Thank you Frank. I wonder if there is a way other than adding a new column...

If you have JMP16, you could create Custom Range:

Or in this case it might be enough if you just change the Bin Label Style from Cutpoints red triangle in same Custom Levels menu.

Default:

Using Low to high - 1

Thanks, but I am using JMP14. There is no "Custom Levels" option. The closest I can get it to add a Binning column:

Any other ideas please?

Just wanted to point out that if the value is continuous, then what happens if you have a value of 3.9? What about 3.999999? The default is that the intervals are left inclusive. Mathematically it would be written as [0,4), [4,8), etc.. 

It sounds like you might want to consider the data as ordinal if the fractions are not possible.

Thanks, Dan. I tried that too. This is what I got after setting it to ordinal:

Unfortunately, I don't have JMP 14 to hand to check - But if you right click on 'ChannelNumber' in the Graph Builder display immediately above, do you see some options that allow you to control the number of levels displayed?

I do have version 14. If you right-click on the channel number, select Number of Levels. From your first example, that would be 12 levels. Not sure why yours defaulted to 3 levels as mine defaulted to all levels. 

I made a simple example, and it looks like this (as a scatterplot rather than boxplot).

Thanks Dan. I was trying to make the ChannelNumber into 3 equal groups, as in 0-3, 4-7, 8-11. Number of Levels to display was set to 3. My original question was how to make it show "0-3","4-7","8-11" at the top, instead of "0-4","4-8","8-11", without adding another column.
