Declares a custom scale break collection. Applies only if the axis' type is "continuous" or "logarithmic".
A scale break allows breaking off a part of the axis to improve the readability of a chart with high amplitude values.
Each object in the breaks array configures a single scale break. Note that a scale break is visible only if its range exceeds the tick interval.
Along with the startValue option, limits the scale break.
Along with the endValue option, limits the scale break.
