Google图表会自动为您选择垃圾箱数.所有容器的宽度均等，高度与容器中数据点的数量成正比.在其他方面，直方图类似于柱状图.

Google Charts automatically chooses the number of bins for you. All bins are equal width and have a height proportional to the number of data points in the bin. In other respects, histograms are similar to column charts.

使用刻度生成算法生成存储桶.默认的存储桶数是使用新的 histogram.numBucketsRule 选项计算的.可能的值为'sqrt'，'sturges'和'rice'.请参见直方图:容器数和宽度

Generate buckets using tick generation algorithm. Default number of buckets is computed using a new histogram.numBucketsRule option. Possible values are 'sqrt', 'sturges', and 'rice'. See Histogram: Number of bins and width
