Definition |
An instance of this DRM class is a <DRM Axis> instance that uses a constant spacing between tick marks and numerical values. The value_unit field specifies the unit of measurement of the <DRM Regular Axis> instance, which shall be compatible with the requirements imposed by axis_type. If axis_type does not require a unit of measurement (e.g., if axis_type requires a value type of INDEX), value_unit shall be set to EUC_UNITLESS. The value_scale field specifies the scale applicable to value_unit. If axis_type does not require a scale (e.g., if axis_type requires a value type of INDEX), value_scale shall be set to ESC_UNI. The interpolation_type field allows the data provider to indicate how best to interpolate the data to points that are between grid points on the axis. The first_value field specifies the first numeric value on the axis. When spacing_type = GEOMETRIC, first_value shall not be zero. The spacing field specifies the distance between tick marks. For ARITHMETIC, spacing is the arithmetic difference between tick marks, such that Tick(i) = first_value + (i × spacing) where i is the ith tick mark. For GEOMETRIC, spacing is the difference between tick marks such that Tick(i) = first_value × (spacingi) The spacing_type field specifies how the spacing value is used to compute tick marks. The axis_alignment field specifies the position of the axis with respect to the axis interval. |
