Multi-Line Screen

The MultiLine Screen is the fourth of five main charting views in QWXL 3.

This new chart allows you to look at control charts for two or more variables at the same time. It is similar to the Relate screen, yet more flexible as you can view more than two variables at the same time.

Busitech’s famous colours are absent from the MultiLine Control chart in order to allow you to see the data points more clearly. As you can see from the above example, viewing more than four variables at one time can be challenging.
