This can easily be accomplished by using JMP's ability to add virtual columns. Assuming your data table has a column that has the percentile value, such as below
![txnelson_0-1690103273400.png txnelson_0-1690103273400.png](https://community.jmp.com/t5/image/serverpage/image-id/55187iD95480CADF36DEE7/image-size/medium?v=v2&px=400)
Then open Graph Builder and drag the percentile column to the X axis
![txnelson_1-1690103403968.png txnelson_1-1690103403968.png](https://community.jmp.com/t5/image/serverpage/image-id/55188i058685E8415AF2A8/image-size/medium?v=v2&px=400)
Next, a virtual count variable needs to be created. Right click on the Percentile column and select Formula
![txnelson_2-1690103569452.png txnelson_2-1690103569452.png](https://community.jmp.com/t5/image/serverpage/image-id/55189iDD8A1989AC554204/image-size/medium?v=v2&px=400)
Change the value of the formula from the original column( in my example Percentile), to just the number "1"
![txnelson_3-1690103734530.png txnelson_3-1690103734530.png](https://community.jmp.com/t5/image/serverpage/image-id/55190i53CCC0D9341556DB/image-size/medium?v=v2&px=400)
If you right click on the Transform(percentile) column, you can select "Rename" and change the name to whatever you want. I chose the name "Count"
![txnelson_4-1690103932811.png txnelson_4-1690103932811.png](https://community.jmp.com/t5/image/serverpage/image-id/55191iD1D5ACC1C745E2BE/image-size/medium?v=v2&px=400)
Close this window and now drag the new virtual column to the Y axis
![txnelson_5-1690104050903.png txnelson_5-1690104050903.png](https://community.jmp.com/t5/image/serverpage/image-id/55192i8F1AA333AEC383E8/image-size/medium?v=v2&px=400)
Now go to the Points control section and change the Summary Statistic to N
![txnelson_6-1690104201646.png txnelson_6-1690104201646.png](https://community.jmp.com/t5/image/serverpage/image-id/55193i20EF7BF0C430436B/image-size/medium?v=v2&px=400)
And then finally right click on the chart, and select Smoother>Remove
![txnelson_7-1690104301722.png txnelson_7-1690104301722.png](https://community.jmp.com/t5/image/serverpage/image-id/55194i2CF39F1A37D159D6/image-size/medium?v=v2&px=400)
And you will get the final graph
