public final class ScaleContext
extends ChartContext

The SCALE option context is used to give contextual information when resolving options.
The context object contains the following properties:

• index: index of the associated data
• scale: scale instance which contains the element to configure
• tick: tick item instance which contains data to be consumed configuring the element (only for ticks)
• label: label item to manage by callback (only for point label context)
