| axis | Set an axis |
| <graphic> | name of the graphic structure |
| -ax <axis> | name of the axis: x, y or z |
| [-sca <scaling>] | scaling function |
| [-f <field>] | field for computing the scale |
| [-min <min>] | minimum value |
| [-max <max>] | maximum value |
| [-step <scales>] | the number of scale labels |
| axis <graphic> -ax <axis> -rm | Remove axis <axis> |
The graphic structure has one global coordinate system (x, y and z axes). Command axis computes the scale for the specified axis (using the minimum and maximum values). The normal scaling function (see section 7.5) is available, but note, that this command does not locate any data points or neurons in a neural network related to an axis.
Parameter -step defines the number of ranges for displaying the labels of the scale for the axis. The whole range of the axis (from <min> to <max>) is divided into uniform parts.
