Enum vega_lite::NiceUnion

pub enum NiceUnion {
    Bool(bool),
    Double(f64),
    Enum(NiceTime),
    NiceClass(NiceClass),
}

Extending the domain so that it starts and ends on nice round values. This method typically modifies the scale’s domain, and may only extend the bounds to the nearest round value. Nicing is useful if the domain is computed from data and may be irregular. For example, for a domain of [0.201479…, 0.996679…], a nice domain might be [0.2, 1.0].

For quantitative scales such as linear, nice can be either a boolean flag or a number. If nice is a number, it will represent a desired tick count. This allows greater control over the step size used to extend the bounds, guaranteeing that the returned ticks will exactly cover the domain.

For temporal fields with time and utc scales, the nice value can be a string indicating the desired time interval. Legal values are "millisecond", "second", "minute", "hour", "day", "week", "month", and "year". Alternatively, time and utc scales can accept an object-valued interval specifier of the form {"interval": "month", "step": 3}, which includes a desired number of interval steps. Here, the domain would snap to quarter (Jan, Apr, Jul, Oct) boundaries.

Default value: true for unbinned quantitative fields; false otherwise.
