Functions of this model
The Code-Subcodes Model is useful for illustrating the hierarchical structure of a code and its subcodes in combination with the code frequencies.
Display in the map
The icon for the selected code is placed directly under the heading of the model. Underneath the, the direct subcodes are placed at a small distance, and a row underneath them the subcodes of the subcodes, etc. Arrows point from each code to its subcodes. Codes with many coded segments can be displayed larger than codes with few coded segments.
Creating a new model and determining its structure
Once you have selected the Hierarchical Code-Subcodes Model in the New Code Model menu of the Start tab, drag a code from the “Code System” onto the map. The following dialog window will appear:
A preview of the model is shown on the map, taking into account the selected options. Click the Use Model button to use the model as it is currently displayed.
Display only activated – When this option is selected, only the subcodes of the selected code that are currently active are taken into account.
X levels of subcodes – A 1 here means: Only the direct subcodes are to be included; a 2 means: their subcodes are also displayed and a 3 means MAXMaps also displays the subcodes of the subcodes.
Code size reflects code frequency – Select this option to display codes with many coded segments larger than codes with few segments. MAXMaps uses three different sizes for the code representation: Codes whose frequencies are in the range of a standard deviation around the mean value are represented in an average size. Codes with more or less coded segments receive a larger or smaller symbol. If the code frequencies are close together, MAXMaps uses only the smallest or the smallest together with the mean symbol size.
Usually the option Aggregate frequencies for parent codes will be enabled, so that the frequencies of the subcodes are taken into account when determining the size of the codes above. Otherwise, the subcodes may be displayed much larger than their upper codes, because the upper codes were only used very rarely or not at all.
Only for activated documents – When creating the model and determining the code sizes, only the currently activated documents are taken into account if this option is selected.
