I have an application to save an axes data into matlab figure after ploting some data into axes.

The action need to be done through axes button down function.

But, the button down fuction is not working after ploting the data into the axes.

The axes created in GUIDE and assigned button down function GUIDE itself.

But we don't have that code to look at so still can't diagnose anything at all without spending our time trying to recreate your symptoms. "Help us help you..."

在 MATLAB Online 中打开

I created a GUIDE-based GUI containing the two functions you mentioned and was able to reproduce the problem (in the future, you should create a simple example demo to make it easy for people to reproduce and diagnose the problem).

When objects are plotted to the axes, the ButtonDownFcn is cleared which is why the ButtonDownFcn worked before plotting but didn't work after plotting.

To fix it, hold the axes before plotting.

% --- Executes during object creation, after setting all properties.
function axes1_CreateFcn(hObject, eventdata, handles)
% hObject    handle to axes1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    empty - handles not created until after all CreateFcns called
hold(hObject, 'on') % <--------  ADD THIS --------------------
plot(hObject, [0 20],[50 1500]);
