示例1: MixedObject

    [
        new MixedObject(40, new Date(2016, 3, 1)),
        new MixedObject(50, new Date(2016, 9, 30)),
    ]
);

// -----------------------------------------------------------------------------
// Test Histogram
// -----------------------------------------------------------------------------

const tScale = scaleTime();

// Create histogram generator ==================================================

let defaultHistogram: d3Array.HistogramGenerator<number, number>;
defaultHistogram = d3Array.histogram();

let testHistogram: d3Array.HistogramGenerator<MixedObject, Date>;
testHistogram = d3Array.histogram<MixedObject, Date>();

// Configure histogram generator ===============================================

// value(...) ------------------------------------------------------------------

testHistogram = testHistogram.value((d, i, data) => {
    const datum: MixedObject = d; // d is of type MixedObject
    const index: number = i; // i is number
    const array: MixedObject[] = data; // data is of type MixedObject[]
    return datum.date;
});

示例2: scaleTime

// zip() -----------------------------------------------------------------------

testArrays = d3Array.zip(testArray1, testArray2);
testArrays = d3Array.zip(readonlyTestArray1, readonlyTestArray2);

// -----------------------------------------------------------------------------
// Test Histogram
// -----------------------------------------------------------------------------

const timeScale = scaleTime();

// Create histogram generator ==================================================

// number - number
let histoNumber_Number: d3Array.HistogramGeneratorNumber<number, number>;
histoNumber_Number = d3Array.histogram();
histoNumber_Number = d3Array.histogram<number, number>();

// MixedObject - number | undefined
let histoMixed_NumberOrUndefined: d3Array.HistogramGeneratorNumber<MixedObject, number | undefined>;
histoMixed_NumberOrUndefined = d3Array.histogram<MixedObject, number | undefined>();

// MixedObject | undefined - number | undefined
let histoMixedOrUndefined_NumberOrUndefined: d3Array.HistogramGeneratorNumber<MixedObject | undefined, number | undefined>;
histoMixedOrUndefined_NumberOrUndefined = d3Array.histogram<MixedObject | undefined, number | undefined>();

// MixedObject | undefined - number
let histoMixedOrUndefined_Number: d3Array.HistogramGeneratorNumber<MixedObject | undefined, number>;
histoMixedOrUndefined_Number = d3Array.histogram<MixedObject | undefined, number>();

// MixedObject - Date
