This example uses the Failure.jmp sample data table, which contains failure data and a frequency column. It lists causes of failure during the fabrication of integrated circuits and the number of times each type of defect occurred. From the analysis, you can determine which factors contribute most toward process failure.
1.
Open the Failure.jmp sample data table, located in the Quality Control folder.
2.
Select Analyze > Quality and Process > Pareto Plot.
3.
Select failure and click Y, Cause.
4.
Select N and click Freq.
5.
Click OK.
Pareto Plot Report Window
6.
Select Label Cum Percent Points from the red triangle menu next to Pareto Plot.
7.
From the red triangle menu, deselect Label Cum Percent Points and Show Cum Percent Curve.
8.
Double-click the y-axis labeled N and rename it Count.
9.
Double-click the y-axis to display the Y Axis Specification window.
In the Maximum field, type 15.
In the Increment field, type 2.
In the Tick Marks and Grid Lines area, select Grid Lines for the Major grid line.
Pareto Plot with Display Options
Pareto Plot with Display Options shows counts now instead of percents, and has a category legend. The vertical count axis is rescaled and has grid lines at the major tick marks.
