21.1 Introduction

Objective Chart provides special support for control charts. Control charts dynamically display some measure of the status of an ongoing process. Temperature, pressure, acidity, and the number of out-of-tolerance items are examples of variables that may appear in control charts.

Objective Chart allows developers to set a variety of limit conditions. During each draw cycle, the data items in the graph are compared to the selected limit condition. Data items that fall outside the limits are automatically highlighted on the screen. Developers can establish other actions to be performed in response to out-of-range data.

The class that implements this functionality is SRGDataWatcher.
