As an user, I would like to keep entering different x,y and z values in the consecutive rows and the points should be plotted in the graphic handle. Thanks in advance for your help. Cheers.

在 MATLAB Online 中打开

I think that's what you need: function test2

figure, h=uitable('data',rand(4,3),'columneditable',true(1,3),'cellEditCallback',@drawtablevalues);
figure, ha=axes;
hp=plot3(0,0,nan);
function drawtablevalues(src,evt)
  data=get(src,'data');
set(hp,'xdata',data(:,1),'ydata',data(:,2),'zdata',data(:,3))
end
end

Best regards, Michael

You'll have to set the parameter for the uitable to be able to be editable. http://www.mathworks.com/help/matlab/ref/uitableproperties.html the link should give you the details about that. Then in the callback/function that you're going to get the table values you need to use the get() function like Table_DATA = get(handles.uitable1,'Value') in GUIDE or equivalent if uitable programmed in an mfile.

Oh and the data coming into the Table_Data and what Michael has above will be as a cell. So i am not sure you can just do a direct plot. you may need to use cell2mat to convert it from a Cell array

I don't know if the behavior has changed with a new Matlab release (it actually shouldn't for backwards compatibility), but I find data to be an array of doubles. No problem plotting that. The little piece of code above is working (at least on my machine).
