If you have selected one or more variables for display in Self-Managed Display, it will appear in status box at bottom of the form. If you left-click on the name of a variable in the status box, a new box (shown below) will appear with a large set of options that can help you learn more about the variable (or simply to delete it from the status box).
A subset of these same options can be obtained from the Quick Scenario Analysis with Tree form by using either a left-click or right-click on a list of parameters within the tree:
There is an option to search for variables and parameters in several locations of the interface, including within Self-Managed Display and the Quick Scenario Analysis with Tree forms. When the search returns a list of parameters or variables as below, a click on any in the list provides explanatory pop-up options (when the browser has enabled pop-ups):
However you reach these explanatory options, here is what they provide:
Define: This option generates a window that will define the variables that are being displayed.
Drivers (Linkages): This option generates a window that graphically displays the drivers of the variable selected (backward linkages or causes) and also the forward linkages or variables driven by it. That is, the form will include a diagram showing the variable in the center and the variables from which it is computed on the left plus the variables to which it contributes on the right. This drivers diagram is derived directly from parsing the computer code of the model. If you float the cursor over any variable name on this screen, a more extended name (or a brief definition) will pop up. You will be able to see these definitions by selecting Show Definitions under the Variables option as well. If you double click on any driver variable or driven variable, the diagram will repaint with the variable selected at the middle. Select Continue to return to the previous screen.
View Historic Analog Variable: This option shows the name of the variable in historical data, if any, that is associated with a forecasted variable in IFs. For instance, if you select the forecast variable POP, it will show that the name of the analog in the data files is Population.
Delete: This option allows you to clear the selected variable/parameter from this box.
View Equations: Selecting this option will bring up a help page that shows the equations used in computing the variable selected.
Explain (Block Diagram): Selecting this option will bring up a help page that shows a diagram that broadly explains how drivers interact for the area of inquiry (agriculture, economics, etc.) that you have displayed in your table. There normally is also textual explanation.
View Code: Select this feature and a new page will be opened that shows the computer code used to express the calculation of these drivers and their interaction in IFs.
Cancel: This option allows you to cancel your selection and return to the previous screen.
