The first command ldgr creates line diagrams to all subgraphs. Then the commands ldgrc or ldgrcld can be used to set components to diagrams. The ldgrc sets the components of the line diagram according to one data record that has been associated to a subgraph. Instead, the ldgrc gets fields through a classifying data frame <cldata> from which a class associated to a subgraph is used to determine the data records from data. Thus, the number of classes in a classifying data frame should equal the number of subgraphs. To remove the line diagram components the whole line diagram should be deleted.
Example (ex7.20): The example displays three line diagrams in two subgraphs. First line diagrams are created and then three components are added to them.

Example (ex7.21): The second example shows how line diagrams can be used to display the ranges of the data in neurons. Two line diagrams "min" and "max" are created and then three components "zn_min", "age_min", "rate_min" are set to the diagram "min" and the corresponding maximum values are set to the diagram "max".

Example (ex7.21): The third example shows how all the data records classified to the neurons can be plotted. The presentation is also known as parallel coordinates.
