本文目的：手动修改已知曲线中的点 功能： 1、可以放缩图像，进行数据点的修改 2、可以选定数据点，并进行修改 3、数据点的修改不能超出相邻点的范围 4、可以移动坐标轴和图像，以方便观察整体图像 5、可以保存修改后的数据 本代码可以自行下载：https://download.csdn.net/download/qq_27261889/10577901
function varargout = movePoints(varargin)
% MOVEPOINTS MATLAB code for movePoints.fig
% MOVEPOINTS, by itself, creates a new MOVEPOINTS or raises the existing
% singleton*.
%
% H = MOVEPOINTS returns the handle to a new MOVEPOINTS or the handle to
% the existing singleton*.
%
% MOVEPOINTS('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in MOVEPOINTS.M with the given input arguments.
%
% MOVEPOINTS('Property','Value',...) creates a new MOVEPOINTS or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before movePoints_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to movePoints_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
