Wide Circular Scales
The Gauge Control allows you to create wide circular scales in addition to the arc and rectangular scales. Like the arc scales, the wide circular scales use a needle to display a value on an arc-shaped graduated scale and are designed to imitate such analog measuring instruments as voltmeters, galvanometers, and multimeters:
There are two types of wide circular scales available in the Gauge Control:
Unbound wide circular scales implemented by the TdxGaugeCircularWideScale class;
Data-aware wide circular scales implemented by the TdxGaugeDBCircularWideScale class.
The possible arc angles depend on the currently selected style of the scale:
Maximum and Minimum Scale Angle Values Specified via the OptionsView Parameters | Scale Visual Styles | Scale Example | |
|---|---|---|---|
1. | AngleStart = 130 AngleEnd = 50 |
| |
2. | AngleStart = 112 AngleEnd = 68 |
| |
3. | AngleStart = 110 AngleEnd = 70 |
| |
4. | AngleStart = 120 AngleEnd = 60 |
| |
5. | AngleStart = 105 AngleEnd = 75 |
| |
6. | AngleStart = 104 AngleEnd = 76 |
| |
7. | AngleStart = 107 AngleEnd = 73 |
