The y-values of each data series are connected by a line. The area between each two lines is filled with a colour. The area chart's focus is to emphasise the changes from one category to the next. Normal - this sub-type plots all values as absolute y-values. It first plots the area of the last column in the data range, then the next to last, and so on, and finally the first column of data is drawn.
面积图图表将值显示为 y 轴上的点。x 轴显示类别。每一个数据序列的 y 值通过一条线连接，每两条线之间的区域由一种颜色填充。面积图图表重点强调从一种类别到下一个类别的变化。
