Creating and initializing graphic structures

The following commands create and initialize a graphic structure. The graphic structure consists of several so-called subgraphs. The subgraphs may have their own graphical elements, but most of the graphical commands change the properties of all subgraphs within the same graphical structure.

There are three possible ways to create a graphic structure:

SOM

To visualize a specific neural network structure (TS-SOM), it can be specified as a parameter. In this case each neuron will have its own subgraph.

Data

Graphics structure can also be created for a data frame, in which case each subgraph will correspond to one data record.

Manual

If no source data or SOM is specified, subgraphs must be created with addsg (see section 7.1.2). If data records are to be displayed in subgraphs, then a source data frame must be connected to a graphic structure with setgdat (see section 7.1.1) and a data record for one subgraph is selected with setsg (Sect. 7.1.2).

In addition, a classified data frame can be connected to a graphic structure, but its use depends on chosen operations.
