大家好,我在用origin计算封闭曲线的面积,遇到点问题,困扰了已经有半个多月。问题具体如下:算封闭曲线的面积,点击area命令,理论上上,应该是封闭曲线内填充黑影,可是实际的情况是,封闭曲线外有一块多余的黑影,百度文库的教程(http://wenku.baidu.com/link?url=mFnFSQeuEImvFD6__qzAN5i1n6S0fz68PbWR1T9ZnKlgDRI90R_m-p2UhDmQNc-pS4H8i_KfHxl0EDt89wSAX96JxDVX4qR2TbGcpVpZEEG)说是要保证曲线环封闭、不间断,按这个思路调整半月有余,还是不见效,故提供数据文件(http://pan.baidu.com/s/1i5BhoOl),请求各位坛友的指教、帮助!

在你的OPJ里面使用的是画出area 图而不是求封闭曲线的面积。

如果希望求封闭曲线的面积的话
1. 把你的数据画成线图(呈现封闭曲线)
2. 选择菜单 “Analysis: Mathematics: Polygon Area”
