示例1: domainExtent

export function domainExtent(numValues: number[], scaleType: 'linear' | 'log'): [number, number] {
    const filterValues = scaleType === 'log' ? numValues.filter(v => v > 0) : numValues
    const [minValue, maxValue] = extent(filterValues)

    if (minValue !== undefined && maxValue !== undefined && isFinite(minValue) && isFinite(maxValue)) {
        if (minValue !== maxValue) {
            return [minValue, maxValue]
        } else {
            // Only one value, make up a reasonable default
            return scaleType === 'log' ? [minValue/10, minValue*10] : [minValue-1, maxValue+1]
        }
    } else {
        return scaleType === 'log' ? [1, 100] : [-1, 1]
