Right-to-left

Circular Gauge can render its elements from right to left, which improves the user experience for certain language users. To do so, set the enableRtl property to true. When this property is enabled, elements such as the tooltip and legend will be rendered from right to left. Meanwhile, the axis can be rendered from right to left by setting the direction property to AntiClockWise. For more information on axis, click here.

The following example illustrates the right to left rendering of the Circular Gauge.
