Remarks

This type is referenced by the LabelOrientation property implemented in the TdxGaugeArcQuantitativeScaleOptionsView class. Possible values include:

Value	Description	Example
loLeftToRight	All label inscriptions within an arc scale are located on imaginary parallel horizontal lines.
loCircular	This value combines two variants of label orientation, represented by the loTangentIn and loTangentOut values. Each label corresponding to its respective major tick mark is located on the outer side of an imaginary straight line parallel to the tangent to the arc scale‘s outer circumference. The direction of the label’s upper part depends on the angle of the circular arc at which the respective major tick mark is located. If the arc angle is within the range between 0 and 180 degrees inclusive (i.e., the upper semicircle), upper parts of the label inscriptions are directed towards the arc scale’s outer boundary. Otherwise, the label inscription’s upper parts are directed towards the scale’s center.
loCircularInward	This value is opposed to loTangentOut. Each label corresponding to its respective major tick mark is located on the outer side of an imaginary straight line parallel to the tangent to the arc scale‘s outer circumference. Upper parts of all label inscriptions are directed towards the arc scale’s center.
loCircularOutward	This value is opposed to loTangentIn. Each label corresponding to its respective major tick mark is located on the outer side of an imaginary straight line parallel to the tangent to the arc scale‘s outer circumference. Upper parts of all label inscriptions are directed towards the arc scale’s outer boundary.
loRadial	The labels are located on the arc scale‘s imaginary radii which match the respective major tick marks. A label inscription is directed from left to right relative to an imaginary radius.
