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 14‑14. By displaying this threshold value, the gauge shows whether the actual sales total is over or under the sales target.

Figure 14‑14 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.

Table 14‑8 shows all the threshold properties and lists the gadgets to which they apply.
