Property

Description

Superclass

· <DRM Axis>

Class

· <DRM Interval Axis>

Subclass

· none

Definition

An object of this DRM class defines a <DRM Axis> that has an interval specified for each axis value (tick mark).

Example(s)

· Consider a <DRM Interval Axis> instance that specifies wavelength bands in centimetres. Its field values are:

axis_type

{ATTRIBUTE, EAC_WAVELENGTH}

value_unit

EUC_METRE

value_scale

ESC_CENTI

axis_value_count

3

axis_interval_value_array

{FLOAT_INTERVAL, LOWER_CLOSED_UPPER_OPEN}
2.40	3.75
3.75	7.50
7.50	15.00

Inherited field elements

field_name	range	Field_Data_Type
axis_type^1		Element_Type
value_unit^2		EDCS_Unit_Code
value_scale^3		EDCS_Scale_Code
axis_value_count^4		Short_Integer_Positive

Field elements

Notes

¹ Gives the type of measurement along the axis, such as distance, pressure, or frequency.

² Specifies the unit of measurement of the axis_type.

³ Specifies the scale applicable to value_unit. If axis_type does not require a unit of measurement (for example, if axis_type requires a value_type of STRING), value_scale shall be set to ESC_UNI.

⁴ Indicates the number of "hash marks" along the axis.
