Q:已有一张图片,如何抓取图片上的各个数据点?

A:Origin提供Digitizer Tool供用户抓取图片上的数据,用户可执行:

1.在菜单栏选择:Tool:Digitizer打开Digitizer的窗口
2.点击import(导入)的按钮,导入原图片




3.点击rotate image(旋转图片)的按钮,调整图片位置



4.关闭rotate image模式后,点击edit Axes(编辑坐标),将坐标移动至于图片吻合的地方,并且按原图键入坐标轴的最大值和最小值



5.点击pick new points(获取新数据点) 按钮,将鼠标移动到数据点并双击鼠标,即可在图片上方观察到该数据点的坐标值



6.如步骤5,逐一获取所需的数据点,完成后点击图片上方Done



7.点击go to data的按钮,即可打开worksheet查看所选择的数据点的坐标值
8.点击go to graph可将选取的数据点绘制成图
9.点击go to image,可返回原图
