示例1: get_best_ticker

const data_range = data_high - data_low
const ideal_interval = this.get_ideal_interval(data_low, data_high, desired_n_ticks)
const ticker_ndxs = [
sortedIndex(this.min_intervals, ideal_interval) - 1,
sortedIndex(this.max_intervals, ideal_interval),
]
const intervals = [
this.min_intervals[ticker_ndxs[0]],

const data_range = data_high - data_low
const ideal_interval = this.get_ideal_interval(data_low, data_high, desired_n_ticks)

// An untested optimization.
// const ideal_mantissa = ideal_interval / ideal_magnitude
// index = sortedIndex(this.extended_mantissas, ideal_mantissa)
// candidate_mantissas = this.extended_mantissas[index..index + 1]
