第一项任务(也是最重要的任务)是计算图形的比例因子，就是说在绘图时每单位的值在高度上要占用多少像素。
The first (and most important) task is to calculate the scaling factor for the graph. This is simply how many pixels in height each value will be worth when it is plotted.

Y 轴比例因子是在第 104 行计算的，方法和上面的柱状图使用的方法一样（请参阅 清单 2）。
The Y-axis scaling factor is calculated on line 104 in the exact same way as in the bar chart example (see Listing 2).
