GWT Google Charts - Histogram Charts
直方图是一个图表，它将数值数据分组为段，并将这些段显示为分段的列。它们用于描述数据集的分布情况，即值落入范围的频率。Google Charts 会自动为您选择段数。所有段等宽，高度与段中数据点的数量成比例。直方图在其他方面与柱状图类似。在该部分中，我们将讨论以下类型的基于直方图的图表。
A histogram is a chart that groups numeric data into buckets, displaying the buckets as segmented columns. They’re used to depict the distribution of a dataset as how often values fall into ranges. Google Charts automatically chooses the number of buckets for you. All buckets are equal width and have a height proportional to the number of data points in the bucket. Histograms are similar to column charts in other aspects. In this section we’re going to discuss following types of histogram based charts.
