Preparing an X hi/lo-R Chart in Infinity QS ProFicient

I am no expert in preparing charts in InfinityQS, but Steve Wise at InfinityQS helped me fab up a trial. I hope this explanation can get one started if they have this software handy.

When using InfinityQS, I found that one could fabricate a X hi/lo chart (see sample) by grouping two XI plots on one chart using the “Group Chart” function. Here are the steps to creating a hi/lo chart using the build-in features of ProFicient.

Steps (Roundness of a Hole)
1) create a test called hole diameter
2) determine the number of points you want to capture of that diameter (in this example, I’m using 10).
3) Add the same hole diameter ten times to the data entry configuration (the software will treat these as sub-tests)
4) Using the sub-test size of 10, create a second test called Diameter Hi and place this in the 11th column (Test #11 in the data entry configuration). Using the Equation Editor, create a formula that will return the maximum of the 10 hole diameters. Here is the formula I’d use max(ch(1):ch(10))
5) Create a third test called Diameter Lo and place in the 12th column. Using the Equation Editor, create a formula that will return the minimum of the 10 hole diameters. min(ch(1):ch(10))
6) Create a group chart showing Diameter Hi and Diameter Lo (group on test)
7) This will create the X hi/lo chart.
[Note: When you create this chart, you’ll also get a group moving-range chart, but this chart can be hidden using the Graph Options.]

Then a second displayed XI chart is made plotting the Range (and is titled “RANGE”, although XI will still show up), calculated by subtracting the low from the high.

No control limits are used, as this software does not allow you to specify specific values. But, warning limits are used just as easily, and they can be specified at 75% of the tolerance for the hi/lo, and as specified based on the process for the Range. They also have pop-ups that indicate when action is needed, opportunity to input the action (e.g. "offset .001") and so forth.

You might consider locking the charts so the users cannot move the windows around. This feature is found by selecting the Preference>Project>Special menu item. Within the Display Mode tab, select Locked Charts.

This is clearly the closest I have come with commercial software to generate these charts. It may confuse a few people in that they state "IX" on both, but it seems to be the only shortcoming seen by an operator.

I found many links in your posts were navigated to incorrect place.

Yes, many of these posts were older, and when the discussion board transferred to new software, not all of the links carried over well.
