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. |
