| ndatplc | Set a data field for an axis to enable data plotting |
| <graphic> | name of the graphic structure |
| -n <name> | name of the data to be plotted |
| -ax <axis> | name of the axis: x, y or z |
| -f <field> | source field |
| -c <cldata> | a classified data |
| [-co <color>] | the color of the data points |
| ndatplc <graphic> -n <name> -rm | |
| Remove a data set | |
This command maps a given data field to the axes of the subgraphs in a way that <cldata> determines, which data records are mapped to which neurons. Before using this command, the definition of the axes should be set with saxis.
Example (ex7.33): In the following example, the correlation of two fields inside neurons is visualized through data plotting.
