From the function HELP: [X,Y] = ginputc(N) gets N points from the current axes and returns the X- and Y-coordinates in length N vectors X and Y. After posting the question, I thought of one way to do it. Syntax [x,y] = ginput(n) [x,y] = ginput [x,y,button] = ginput() Description. I am following a certain path along the image and need to zoom-in to get a precise coordinates, matlab; image-processing; coordinates; zooming; ginput; r9 fan. Learn more about ginput, plot My question is rather simple, does anyone know a way to have matlab's ginput ignore subsequent clicks at the same location?. Input data using the mouse . This works on either of the subplots -- I can move the cursor from one to the other subplot and pick the point on either one. only apostrophes for strings, just like in your normal code: 4 is integer, 4. e. Is there anyway I can the subplot number on which i clicked for ginput from the axes handle properties ? or some other way ? matlab; matlab-figure; Share. Ginput in a GUI. This is the route to go to deal with events like this. [X, Y]= ginput(2) xmin=min(X) xmax=max(X) ymin=min(Y) ymax=max(Y) In this code I define the corner of the square (the user defines the two points with the ginput). I get the length of X from ginput, then in a loop, I plot X(i),Y(i), prompt to enter a thickness for that value then delete that plot marker and move on to the next. Matlab has the ginput for getting the (x,y) value of where you have clicked on the graph. Asking for help, clarification, or responding to other answers.

Start Hunting! ginput函数是MATLAB提供的一个功能强大、易于使用的工具，用于通过鼠标进行交互式点选。本文将详细介绍ginput函数的用法及其示例代码，帮助读者更好地理解和使用该函数。ginput函数是MATLAB提供的一个基于图形界面（GUI）的函数，允许用户通过鼠标在图形窗口中进行交互式点选操作。 In Matlab and Octave, I understand there is a function called ginput with which the user can click on points in the plane to plot them. . It works fine in my older matlab code, but I'm running a version of that code now in Matlab Engine (being called from an external program) and I can't get ginput to ever act on the axes in the figure I want (there is only one figure, and only one axes). Search Answers Answers. Identify five coordinates in a set of axes using As an alternative method you can utilize MATLAB's datacursormode object, which does not block zooming/panning of your figure window. I'm not able to do it. Here are some fixes to the code. for example: 89. npnne fyij wqros fazmp gpln uvbwi rirhc fwztkd curoy rdbpl
