A QR code (abbreviated from Quick Response code) is a type of matrix barcode (or two-dimensional barcode) first designed in 1994 for the automotive industry in Japan. A barcode is a machine-readable optical label that contains information about the item to which it is attached. In practice, QR codes often contain data for a locator, identifier, or tracker that points to a website or application.
QR码（快速响应码的缩写）是一种矩阵条形码（或二维条形码），最初于1994年为日本汽车行业设计。条形码是一种机器可读的光学标签，包含与所附物品有关的信息。实际上，二维码通常包含指向网站或应用程序的定位器、标识符或跟踪器的数据。
A bar chart or bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column chart. A bar graph shows comparisons among discrete categories. One axis of the chart shows the specific categories being compared, and the other axis represents a measured value.
条形图或条形图是一种用矩形条表示分类数据的图表或图形，矩形条的高度或长度与其所代表的值成正比。可以垂直或水平绘制条形图。垂直条形图有时被称为柱状图。条形图显示了离散类别之间的比较。图表的一个轴显示正在比较的特定类别，另一个轴表示测量值。
苹果、桔子和香蕉是离散类别的一个例子。如苹果2斤，桔子3斤，香蕉1斤。
A histogram is an approximate representation of the distribution of numerical data. To construct a histogram, the first step is to "bin" (or "bucket") the range of values - that is, divide the entire range of values into a series of intervals - and then count how many values fall into each interval. The bins are usually specified as consecutive, non-overlapping intervals of a variable. The bins (intervals) must be adjacent and are often (but not required to be) of equal size.
直方图是数值数据分布的近似表示。要构建直方图，第一步是“bin”（或“bucket”）值的范围——也就是说，将整个值范围划分为一系列区间——然后计算每个区间中有多少值。箱子通常被指定为变量的连续、不重叠的间隔。The bins（间隔）必须相邻，并且通常（但不要求）大小相同。bin: 大箱子。
以分数为例，如[0,20) 10名, [20, 40) 15名 ... [0, 20)是左闭右开区间，即20 > x >= 0.
