Graph
サマリ
The Graph class helps you in creating graphs of different types. Also, you can specify general graph properties such as the title, graph axes, and legend information.
説明
Graphs assist you in presenting information about map features and the relationship between them in a visual, easy-to-understand manner. Graphs may also be created for nonspatial tabular data and can show both additional information about the features on the map or the same information in a different way. Graphs are complementary to maps in that they simply and visually convey information that would generally be summarized numerically or explored from tables. With a graph, it is easy to quickly compare features to gain insight into the functional relationship between the features and thereby visualize the distribution, trends, and patterns in the data that would otherwise be difficult to see.
