Constraints

Return to Plot Options Menu

Use the Constraints menu option to specify upper and lower limits on design variables. The plot will be shaded to show the feasible and infeasible design points based on the constraints.

Control Name	Use/Options
Variable Name	Lists the design and response variables set in the trade study.
Low/minimum	Shows the value set in the trade study. Change the limit by either entering a value in the text box or dragging the slider.
High/maximum	Shows the value set in the trade study. Change the limit by either entering a value in the text box or dragging the slider.
Dock	Closes the Constraints panel and opens the selected variable control panel at the bottom of the plot so that the whole plot can be seen while the constraint is changed. If the Constraints panel is opened while a variable is docked, the control panel for that variable displays as shown below. Return -- reinserts the selected variable in the Constraints panel. Can be accessed from the docked variable or from the Constraints panel.
Enumerated values	The Constraints panel can handle enumerated values. The values list will be displayed as individual entries with a checkbox next to each; uncheck the corresponding box to remove the value from the plot. Numeric enumerated values can also be turned into a normal slider by clicking the button (see the matType line above). Click the button to change back to the enumerated list.
Boolean values	The Constraints panel can handle Boolean values. The values list will be displayed as individual entries with a checkbox next to each; uncheck the corresponding box to remove the value from the plot.

When constraints are applied to a graph, the infeasible points are retained, but are grayed out. A new entry is added to the legend for the infeasible points.

Infeasible points can be hidden (and reshown) by using the Hide infeasible designs option from the View Controls toolbar.
