Combination Graphs

A combination graph uses different types of data markers to display different series of data.

The Java-client and HTML-client user interface for changing the graph type presents combination graphs as a separate graph type. However, the Graph bean API does not have separate constants for combination graphs. The combination graphs that are exposed in the user interface are bar graphs in which the Series.getMarkerType for any series returns a value other than BaseGraphComponent.MT_DEFAULT. In the API, you can also start with a line graph or an area graph and set the MarkerType property of any series to a value other than MT_DEFAULT.

Standard use of a combination graph

Use combination graphs to clarify or emphasize relationships among data series.

Available varieties of combination graphs

The MarkerType property of a Series determines the type of data marker that represents the series. Valid values of the MarkerType property are:

You can have a single-Y combination graph or a dual-Y combination graph.

Graph properties for combination graphs

The DepthRadius and DepthAngle properties of the Graph object together specify whether a combination graph appears to have depth.

Data structure of combination graphs

The data structure of a combination graph is the same as for bar, line, and area graphs.

Data guidelines for combination graphs
