Creating Rules

You can ignore points in the data set when you fill your lookup table.

By defining a region to include or exclude such points, you create a rule for the table filling.

For example, you might want to fill a lookup table that has a range of operating points that is smaller than the range of the experimental data.

To ignore points in the data set:

1. Select Data -> Plot -> Data Set. This displays the view of where the breakpoints lie in relation to the experimental data.
2. To define the region that you want to include, left-click and drag the plot. For example, see the following display.

1. This region defines a rule in the Table filling rules pane.

   

3. To fill the table based on an extrapolation over these data points only, click Fill Table.

The display of the surface now shows the table filled only by reference to the data points that are included in the range of the table.

You can now review your data set using the options in the View and Plot panes of Data Sets.

You can add any number of rules to follow when filling tables. For example, you might be aware that a particular test run included in the chosen area is not good data. You can click and drag to enclose any chosen point, then right-click that rule (in the Table filling rules pane) and select Exclude Points. You can set any number of rules to make sure you fill the table by using just the points you are interested in.

Right-Click Options

Right-clicking the Table filling rules pane gives you the following options:

• Enable Rule: Apply the rule to the data.
• Disable Rule: Do not apply the rule, but also do not delete it.
• Exclude Points: Do not include these points in table filling.
• Include Points: Include points in table filling.
• Promote Rule: Change order of rules.
• Demote Rule: Change order of rules.
• Clear Rule: Delete this rule.

You can use these options to enable an iterative process. You can fine-tune the selection of data points: try different selections of data to fill your tables, check the results, then reuse the same rules for the same or different tables.
