Setting the Selected Point

You can use the Taguchi Main Effects Viewer to set a selected point for which to calculate and display the Taguchi response metrics, allowing for a determination of the benefit of that selected point over an optionally specified baseline design.

  1. From the Runtime Gateway, click a Taguchi Robust Design component that has completed execution from the Sim-flow tab or from the model explorer.

  2. Click the Graphs tab, and click the button.

    Isight loads the results from the Taguchi Robust Design component into the Main Effects Viewer.

  3. Click the Graphs subtab.

  4. In the Selected Point area in the upper left section of the Main Effects Viewer, do one of the following:

    • Select Best Levels to set the selected point to the combination of factor levels that provides the estimated best metric values.

    • Select Worst Levels to set the selected point to the combination of factor levels that provides the estimated worst metric values.

    • Select any combination of factor levels by clicking the graph on the desired level for any factor. User selected levels is selected automatically in this case.

      If you select specific user-selected levels and then switch to Best Levels or Worst Levels, the user-selected levels are retained so that if you select this option again, you do not lose your selection. This behavior allows you to interactively select levels and compare the benefit at those levels with the benefit at the best/worst levels in an iterative fashion. However, if you select Best Levels or Worst Levels and then click in the graph on a new level for any factor, this set of levels (best/worst levels modified by the manual selection for one of the factors) is now considered the new set of user-selected levels.

    • Click the arrow next to Based on to set the selected point on each graph independently for Each Metric (default) or to set the selected point on both graphs to the same point based on the best or worst levels for the selected metric (S/N Ratio, Sensitivity, Beta 1, Beta 2, or Beta 3). This option is not available when only the S/N Ratio graph is displayed or when the selected point is set to User selected levels.

    Isight shows the selected points with a green filled circle symbol on the corresponding level for each factor.

  5. Click Close to exit the Main Effects Viewer and to return to the Graphs tab.

    Isight does not save any selections or settings when you close the Main Effects Viewer.
