Detailed Description

Base class for legend definition.

Legend is an object that contains a key to the plot styles used in graphs. The key contains a sample of the plot style used and a corresponding text label.

The Colormap legend is a special case because in addition to the plot style, the plot z-range is shown in the legend.

The size of legend can be queried and the location can be set.
