Data cursor on GUI plot

Hi, I have a GUI with a table and a plot as you can see: </matlabcentral/answers/uploaded_files/4822/guisanstitre.png>

I woudl like to put a Data cursor on my plot to get the value of points.

I try to do :

hPlot=plot(handles.axes1,courbe);figure(gcf) % display my plot
  dcm_obj = datacursormode(hPlot);
  datacursormode on;
  set(dcm_obj,'UpdateFcn', @myupdatefcn )

but matlab return an error:

Error using datacursormode (line 144)
Invalid figure handle

Could you help me, maybe there is a better way to get a data cursor?

Thank you

I think the following line may help you

[x,y] = ginput(1)
