The most convenient way to represent component performance characteristics ('maps') is in a graph. Several types of maps exists for different component types. Some component types like compressors, fans combustors and turbines have special graphical representation layouts that are commonly used in the gas turbine community. For many other relations such as in scheduler-, control- and case control components, simple 1-D and 2-D maps are used for which simple X-Y plots are used for graphical representation.

In maps that are scaled, a yellow rectangle represents the map design point (DP) to which the engine design point is scaled. If the map graph is scaled using the Map | Scale to model design point menu option, then naturally the rectangle represents the actual engine DP. See example of a compressor map. Map graphs can be saved or copied to the clipboard or to files in bitmap or meta file format using the Copy and File menus in the graph window. Note that when printing or exporting the map graph to bitmap or meta formats, only if the map is scaled also the rectangle is drawn in the map.
