Threshold properties

Threshold properties define thresholds, which you use to identify meaningful values. For example, in a linear gauge that displays a sales total, you can add a threshold that identifies the target sales amount, as shown in Figure 17-14. By displaying this threshold value, the gauge shows whether the actual sales total is over or under the sales target.

Figure 17-14 also shows the threshold properties set to create the threshold. You can specify a label, create a threshold line or a threshold zone, specify a threshold value or range of values, and format the line and marker. You can create multiple thresholds for a gadget.
