分析了古建筑设计中由于古尺的消失和古制单位与计算机绘图单位的不匹配而使得古建筑设计所面临的问题。
The questions caused by the disappearance of old chi and incompatibility between ancient size and computer drafting are analyzed.
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.

映射模式和转换-尽管缺省情况下你用像素单位绘图，但是你并没有被限制要这样做。
Mapping modes and transforms Although by default you draw in units of pixels, you are not limited to doing that.
利用此程序，可以得到纵轴上有相对单位及对数单位两种格式、横轴上可随意定义绘图区间的输出曲线。
With this program, we can get output curves that the Y axis has "Relative unit" or "LOG unit" while in X axis the plotting range can be arbitrarily defined.
