TdxGaugeArcQuantitativeScaleOptionsView.AngleStart Property

Specifies the start position corresponding to the minimum value which can be displayed by an arc scale.

Declaration

delphi

property AngleStart: Integer read; write;

Property Value

Type
Integer

Remarks

The AngleStart and AngleEnd properties specify the positions of the minimum and maximum values, displayed by the circular, wide circular, three-fourth circular, half-circular, or quarter-circular scale.

The AngleStart property value can be either more or less than the AngleEnd property value. Moreover, you can assign both positive and negative angle values (in degrees) to the AngleStart and AngleEnd properties to position the scale’s end and beginning in different ways. The angle increases in the counterclockwise direction and decreases in a clockwise one.

The arc scale type can impose certain restrictions on values that can be assigned to the AngleStart and AngleEnd properties:

Scale Type	Imposed Angle Value Limitations
Circular	No limitations, any values can be assigned to the AngleStart and AngleEnd properties. Refer to the Full Circular Scales subtopic for more information.
Wide Circular	The range between the AngleStart and AngleEnd property values depends on the currently selected visual style of a wide circular scale. Refer to the Wide Circular Scales topic for the full list of angle ranges.
Three-Fourth Circular	The range between the AngleStart and AngleEnd property values depends on the currently selected visual style of a three-fourth circular scale. Refer to the Three-Fourth Circular Scales subtopic for the full list of angle ranges.
Half-Circular	Both the AngleStart and AngleEnd property values must be within the range between 0 and 180 degrees. Refer to the Half-Circular Scales subtopic for more information.
Left Quarter-Circular	Both the AngleStart and AngleEnd property values must be within the range between 180 and 90 degrees. Refer to the Quarter-Circular Scales subtopic for more information.
Right Quarter-Circular	Both the AngleStart and AngleEnd property values must be within the range between 90 and 0 degrees. Refer to the Quarter-Circular Scales subtopic for more information.
