To add to a legend:
| Note Only a single legend item may exist for a given visualization. If you are inserting multiple visualization items into an existing legend, only legend items for those visualizations not already represented will be added to the legend. |
Each legend entry consists of a sample and a label. For example, in Figure 5-1, the sample for the first entry is an unbroken line of thickness 1, and the label is Noisy Sine Plot. The sample for the second is a broken blue line of thickness 2, and the label is Clean Sine Plot.
| Tip To alter your legend's properties such as in the example shown previously, display the property sheet. To do this, double-click the border of the legend box. |
