Half-Circular Scales

In the Gauge control, the Half-Circular scales are implemented as the TdxGaugeCircularHalfScale and TdxGaugeDBCircularHalfScale objects, corresponding to unbound and data-aware scale versions, respectively:

Since Half-Circular scales occupy only the upper half of the full circular scale layout, the possible arc angles are within the range between 0 and 180 degrees:

In half-circular scales, the range of displayed values can occupy any part of the arc lying between 0 and 180 degrees:

As in the case of full circular scales, you can swap the starting and ending angle values, inverting the scale’s range of displayed values:

Note that a particular shape of half-circular scale’s background layer depends on the currently selected style.
