[英]How to plot multiple clicked points on a Matlab axes?
Using ginput
(or ginputax
) I ask my user to click on an axes 10 times (for spectrum baseline correction). 使用ginput
(或ginputax
),我要求用户单击轴10次(用于频谱基线校正)。
My axes is based on a GUIDE GUI. 我的轴基于GUIDE GUI。
Essentially this begins like this 本质上,这是这样开始的
plot(handles.axes_preview, ppm, xf_base, 'w-', 'LineWidth', 2);
spline_ppm = ginputax(handles.axes_preview, 10);
I'd like to plot each click (as ro
) as they're being input , so the user has some feedback of where they clicked. 我想在输入时绘制每次点击(as ro
),以便用户对他们点击的位置有一些反馈。
Any ideas how to code this? 任何想法如何编写此代码?
How about a simple loop? 一个简单的循环怎么样?
axis(handles.axes_preview); %// make handles.axes_preview the current axis
hold on
for ii = 1:10
coords(ii,:) = ginput(1);
plot(coords(ii,1),coords(ii,2),'ro')
end
Also, you may want to add 另外,您可能要添加
set(handles.axes_preview),'XLimMode','manual');
set(handles.axes_preview),'YLimMode','manual');
at the beginning to prevent the axis scale from automatically changing as points are input by the user. 刚开始时防止轴刻度随着用户输入点而自动更改。
