Create a Control Chart in Seconds

Need to Draw Control Charts But Don't Know How?

I am very impressed with QI Macros Software. I work with Excel eight hours a day and thought that I had written macros that made me efficient.

The Control Chart and Histogram macros in QI Macros alone have saved me hours of work and allowed me to present data to management in a format that is meaningful.

What is a Control Chart?

Control Charts Evaluate Process Performance Over Time

A control chart is a smart line graph. It performs calculations on your data and displays:

  • the average or median as a center line
  • the amount of variation in data using control limit lines.

Control Charts Contain These Key Elements

As data moves through the zones created by these control limits, a control chart highlights data points or trends that should be investigated.
