TdxGaugeCustomCircularScale Class

The base class for circular scales.

Declaration

TdxGaugeCustomCircularScale = class(
    TdxGaugeArcQuantitativeScale
)

Remarks

This class implements the functionality required by both the unbound and data-aware circular scales.

The circular scales are designed to imitate speedometers, tachometers, stopwatches and similar measurement instruments used individually or in complex dashboards. Unlike the three-fourth-, half- and quarter-circular scales, the circular scales impose no restrictions on the OptionsView.AngleStart and OptionsView.AngleEnd property values.

The TdxGaugeCustomCircularScale class is the ancestor for the TdxGaugeCircularScale and TdxGaugeDBCircularScale classes which only publish its properties.

You do not need to create instances of the TdxGaugeCustomCircularScale class. Use its descendants instead.
