Design Editor Displays

The following example shows the display after creating an optimal design.

When you first see the main display area, it shows the default Design Table view of the design (see example above). There is a context menu, available by right-clicking, in which you can change the view of the design to 1-D, 2-D, 3-D, and 4-D Projections and Table view (also under View menu). This menu also allows you to split the display either horizontally or vertically so that you simultaneously have two different views on the current design. The split can also be merged again. After splitting, each view has the same functionality; that is, you can continue to split views until you have as many as you want. When you click a view, its title bar becomes blue to show it is the current active view.

The Design Tree

The currently available designs are displayed on the left in a tree structure.

The tree displays three pieces of information:

• The name of the design, which you can edit by clicking it.
• The state of the design:
• The icon changes from  if it is empty, to the appropriate icon for the design type when it has design points (for example,  optimized, as in the toolbar buttons for Optimal, Classical, and Space-Filling designs).
• The icon changes to  when design points have been added using a different method (for example, augmenting a classical design with optimally chosen points). It becomes a custom design style. You can mix and match all design options in this way.
• A padlock appears (  ) if the design is locked. This happens when it has child nodes (to maintain the relationship between designs, so you can retreat back up the design tree to reverse changes).
• The design that is selected as best. This is the design that is used for matching against experimental data. The icon for the selected design is the normal icon turned blue. When you have created more than one design, you must select as best the design to be used in modeling, using the Edit menu. Blue icons are also locked designs, and do not acquire padlocks when they have child nodes.
• You can reach a context menu by right-clicking in the design tree pane. Here you can delete or rename designs and add new designs. Choose Evaluate Design to open the Design Evaluation window. Properties opens the Design Properties dialog, which displays information about the size, constraints, properties (such as optimality values), and modification dates of the selected design.

The information pane, bottom left, displays pieces of information for the current design. The amount of information in this pane can change depending on what the design is capable of; for example, only certain models can support the optimal designs and only these can show current optimal values.

Display Options

The Design Editor can display multiple design views at once, so while working on a design you can keep a table of design points open in one corner of the window, a 3-D projection of the constraints below it, and a 2-D or 3-D plot of the current design points as the main plot. The following example shows several views in use at once.

The current view and options for the current view are available either through the context menu or the View menu on the Design Editor window. Also in these menus is the Print to Figure command. This option copies the current view into its own figure, allowing you to use the standard MATLAB plotting tools to annotate and print the display.

The Viewer Options item in the View menu opens windows for configuring details of the current display. You can change basic properties such as color on all the projections (1-D, 2-D, 3-D, and 4-D). For the table view, you can alter the precision used for displaying data and set up a filter to selectively display certain ranges of values. You can rotate all 3-D views as usual. You can double-click the color bar to edit the colormap.

You can also view projections of constraints; see Applying Constraints.
