Introduction to Selectors
Sample Model: Check Box
This section provides an example of Selectors functionality using the Check Box selector to illustrate.
The Check Box is a simple selector that uses the Value function. It has two positions, checked and unchecked. When the check box is checked, it inserts a certain value on the target cell. When the status is unchecked, it inserts a different value. Both values are defined by the designer when creating a model.
Let's explore how the check box works:
In the Source Data area, we selected two values: 0 and 1. The number 0 indicates that the check box is unchecked, while 1 indicates that the check box is checked. You can select any values that you need.
In the Insert In area, we selected the cell A7 as the destination or target row. You can select any empty cell that you want.
When the check box is checked, the check box inserts the number 0 in the target cell A7. When the check box is unchecked, it inserts the number 1 in the target cell A7.
Check Box is unchecked: The number zero (0) is inserted in the target cell.
Check Box is checked: The number one (1) is inserted in the target cell.
Check Box functionality can become powerful when combined with other components using the Dynamic Visibility function. Suppose that when a component using Dynamic Visibility is linked to a cell that contains the number 1, the component becomes visible. Any other number or value means that the component is invisible (hidden). If you combine the Check Box and another component using the Dynamic Visibility function, the result is extremely powerful.
Suppose you want to create a model that gives the user the option to show or hide a chart. Once you configure the chart you use the chart's Dynamic Visibility functionality to link the chart's Display Status parameter to the Check Box Target cell (in this case, cell A7).
- Click the Chart to edit the Property Window.
- Click the Behavior tab (third tab from left to right).
- Click the Dynamic Visibility icon and link it to the Check Box target cell (in this case, A7).
The model is ready to be tested and published. By default, when you run the model, the chart won't be visible. Users must click on the Check Box to enable the chart. This function adds interesting effects to your presentations.
