Table View

When you select a table in the branch tree (in feature or manual calibration), you see the Table view. In CAGE, a table is defined to be either a one-dimensional or a two-dimensional lookup table. One-dimensional tables are sometimes known as characteristic lines or functions. Two-dimensional tables are also known as characteristic maps or tables. CAGE regards them both as similar objects.

Each lookup table has either one or two axes associated with it. These axes are normalizers.

For example, a simple MBT feature has two tables:

• A two-dimensional table with speed and relative air charge as its normalizers
• A one-dimensional table with AFR as its normalizer

For feature calibration (filling the tables by comparing a strategy and a model), see Calibrating the Tables.

For an example of manual calibration (filling tables using experimental data), see Filling Tables from Data Tutorial.

The example following is a feature view. In manual calibration, you do not see the comparison pane because you are not comparing tables with a model.

The parts of the display are numbered and labeled as follows:

1. The table pane displays the breakpoints of the normalizer and the values of the table. (See Viewing a Table.)
2. The graph of the table pane displays the table values graphically. (See Using the Graph of the Table.)
3. The comparison-of-results pane displays a comparison between the current output of the strategy and the feature model. (See Comparing the Strategy and the Model.)

Note    You can view the History display by selecting View -> History. For information, see "Using the History Display.

This section describes each of these parts in detail.
