Displaying the Model or Feature

Using Display Options

The Plot Type drop-down menu gives the options on how to display the model or feature, as shown below.

Use the options in this menu to display the model or feature as described in the following sections.

For information about the Movie option, see Making Movies.

When plotting multiple models or features, it can be useful to link axes rotation or use common Y- or Z- ranges. Use the display options (toolbar button or View menu).

In any of these views you can select View > Statistics, or click the equivalent toolbar button. This opens a dialog box with a list of the summary statistics (mean, standard deviation, maximum, or minimum) of your currently selected model, strategy, or error for the current display.

For the plots (not movie, single value or tables) you can use the File menu or toolbar to print, copy to clipboard or print to figure. You can also export plot values to CSV file. See Printing and Exporting the Display.

You can alter display options for all plots (not value or tables) with the View menu or toolbar button.

Surface

You can rotate the surface plots by left-clicking and dragging.

If you are using the surface viewer to view a feature, you can choose the following options to display:

• Model

• Strategy

• Prediction Error

• Error (between the model and the strategy)

When viewing models there are no strategy options. You can choose these options from the drop-down menus for Surface 1 Height, Surface 1 Shading, and Surface 2 Height, as illustrated below.

You can view any of these options alone as a primary surface (by leaving the last two options set to None). You can add a second option to shade the primary surface, for example to color your model surface with the error between the model and the strategy, to highlight problem areas.

When you choose to shade a primary surface, a color bar appears to the right of the plot to show you the scale. You can change the maximum and minimum values of the shading factor by typing in the edit boxes above and below the color bar. You can see an example like this in Viewing a Model or Strategy.

You can add a second surface to display any two of the options simultaneously, for example, your model and your strategy.

If you have a boundary model, you can display the boundary by selecting the check box.

Select the Inputs to plot from the X-axis and Y-axis drop-down lists, and specify the ranges of inputs in Value controls. See Setting Variable Ranges.

Note   For information on the two different error displays available using the surface view, see the next section, Displaying Errors.

Contour

You can specify where you want contours by clicking Set Contour Values. Use the check box to return to automatic contour value selection. You can also control number of contours, filling and labels in the display options (toolbar or View menu).

You can enable Cursor Mode (use the View menu or toolbar button) and then click on the plot lines to display the values at a point (plotted with an X). The values are shown in the status bar.

Back to Top

Line

A line plot - you can display up to three different lines (strategy, model, prediction error and error between the model and strategy). Use the Line drop-down lists to select what to plot. You can select the check box to clip to a boundary if available.

You can enable Cursor Mode (use the View menu or toolbar button) and then click on the plot lines to display the values at a point (plotted with an X). The values are shown in the status bar.

Back to Top

Single Value

This displays the value of the model, strategy, prediction error or error at the point you have specified in the variable value boxes.

Back to Top

Multiline

Select the variables to plot from the X-axis and Line colors drop-down menus. Control the number of lines by altering the Values. You can use the check box to clip to a boundary if available.

You can enable Cursor Mode (use the View menu or toolbar button) and then click on the plot lines to display the values at a point (plotted with an X). The values are shown in the status bar.

Back to Top

Table

You can select a 2-D or 1-D table to display. Select the check box to mark cells outside the boundary.

Choose variables to be the axes of your table and set the range and number of points in the same way as for all the plots. Set single values for any other variables. For more information, see Setting Variable Ranges.

For 2–D tables you can use the Cell values drop-down menu to select whether to display the model output or the prediction error.

For 1-D tables you can select what to display in columns 1, 2 and 3: Model, Prediction error, Strategy or Error (strategy – model) (for features), or choose None for 2 and 3 to display only a single column. When viewing models there are no strategy options.
