An E3Chart is an ActiveX component specially created to work with Elipse E3. With it, users can display charts with Tags varying in real-time, as well as historic data stored on a database.

An E3Chart is formed by several collections. A collection is a special object that manages a set of similar objects. An E3Chart contains the following collections:

•Collection of Axes: Manages the Axes of an E3Chart, where different scales linked to Pen's data can be configured

•Collection of Pens: Manages a set of Pens created to manipulate data sequences represented on an E3Chart

•Collection of Legend Columns: Manages the columns of an E3Chart's Legend, where information about Pens is then displayed

•Collection of Queries: Manages queries containing information about Pens, such as charts displaying historical data already stored on a database

To use E3Chart features, follow these procedures:

1.Right-click a Screen and select the Insert - E3Chart option.
