Need to Update Several X bar R Charts on a Regular Basis?

QI Macros XbarR Dashboards for Manufacturing Can Help!

The purpose of the XbarR Chart dashboard is to evaluate the stability of multiple measurements in a manufacturing environment.

The XbarR Chart dashboard has a few main components:

  • Data Entry Sheet
    Just type data into the yellow/white input areas on the data sheet. Use 2-5 samples:
  • xbarr-dashboard-1

  • XbarR Chart with flat limits for fixed sample sizes (2-5):
  • xbarr-dashboard-2

  • XbarR Chart with "skyline" limits for varying sample sizes (2-5):
  • xbarr-dashboard-3

Creating the XbarR Chart Dashboard

  1. Input measurement titles, specification limits and data into the data sheet as shown above.
  2. Click on the tab you would like to create a dashboard from - XbarR Chart, Skyline or Precontrol:
  3. XbarR Dashboard Tab

  4. Use the Next/Prev buttons to look through the various charts to make sure they are what you want:
  5. Previous Next Button

  6. When you have the right data and charts, click on the CREATE DASHBOARD button. This will create new worksheets for each chart as well as the dashboard showing just the X Charts:

  8. Delete the unused worksheets, as they are no longer needed.
  9. You can rearrange the charts on the dashboard by clicking and dragging them around.
  10. You can copy other charts from the new worksheets (e.g., Histograms) and paste them onto the dashboard:
  11. XbarR Dashboard with Added Charts

  12. You can then continue to add data to the data sheet and update charts by clicking the "Refresh Charts," "Refresh Charts w Stability," or "Refresh Charts w Rules" buttons on the data sheet. Refresh with Stability will run QI Macros stability analysis on all control charts. Refresh Charts with Rules will run QI Macros stability analysis on all control charts and show specific rules violated.
  13. If you save this workbook as an Excel "Shared" workbook, you could have multiple people updating various measurements. Just refresh the charts every so often. Anyone can then look at the dashboard.

I think you'll find this a very powerful feature of QI Macros. Creating dashboards of key measures quickly and easily. And keeping them up-to-date with a click of a button.
