User input nodes and user output nodes
• • • 5.2
You can change the values in the user input nodes directly. The user output node, Net present value, shows a Calc button. Click it to compute and see its value. Double-click the Model details node to open a diagram showing details of the model (the influence diagram shown above).
An existing model opens in browse mode. In this mode, the browse tool button is highlighted in the navigation toolbar, and the cursor looks like this:
In browse mode, you can change input node values, view output node results, and examine the model by opening windows to see more detail.
Viewing User input nodes
- An input field lets you see a single number or text value. Click in the box to edit the value. An input field can be configured to be Number only, Text only, Number or text only or (the default) any expression. When any expression is allowed, you must should put matching quotes (single or double) around a text value; otherwise, if it happens to be a valid expression, the entry will be interpreted as an expression rather than text.
- Click the List button to open a list of values, usually defining an Index. To change a value, click in its cell. For more about lists, see Editing a list.
- Click to open an edit table showing an editable array with one or more dimensions displayed as a table. For more, see Editing a table.
- Click to view and edit a probability distribution in the Function Finder. For more, see Probabilistic calculation
Viewing User output node values
- Click the Calc button to compute and display the value of this output variable. When computing is complete, it shows a number in this node, or, if it’s an array, it changes to the Result button and opens a Result window showing a table or graph. See Result Tables and Graphs for more.
- The Result button shows that an array has been calculated. Click it to open a Result window showing a table or graph. See Result Tables and Graphs for more.
