Selecting Regions of the Data

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

For example, in this tutorial the experimental data ranges over values that are not included in the lookup table. You want to ignore the values of engine speed that are greater than the range of the table.

To ignore points in the data set:

  1. Select Data -> Plot -> Data Set. This returns you to 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. Highlight all the points that are included in your table range, as shown.

  1. To fill the table based on an extrapolation over these data points only, click Fill Table. This opens the History display again.
  2. In the History display, select version 3 and 4, using Ctrl+click. The following display shows a comparison between the table filled with two different extrapolations.

  3. Click Close to close the History viewer.
  4. Select Data -> Plot -> Surface to view the surface again.

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 have filled a lookup table with values taken from experimental data.
