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
