it was a routine way for graph- drawing based on coordinate data in application software to program and graph processing,because from coordinate data to graph it is uniqueness.in hydrologic analysis,we calculated related data according to figure parameters,as using rainstorm isoline to reckon average rainfall in the river basin.through examples and analysis,the paper proposed methods for curve numerical translation and area calculation by vb.

在应用程序编制和图形处理的软件系统中由坐标数据可以绘出图形是常规的途径，但有曲线图形，要生成坐标数据，至今还没有通用的方法，因为由坐标生成图形是唯一的，而反过来由图形转换为数据是非唯一的。在水文分析计算时，有时需要根据图形参数进行有关数据的计算，如用暴雨等值线图计算流域平均雨给出量的时候。通过分析和计算实例提出了利用vb实现可满足使用要求的曲线数值转换和封闭图形的面积计算方法。
