I created an axes - My_Axes (using GUIDE but I think it doesn't matter) - and specified a 'ButtonDownFcn' to treat mouse clicks on the created graph. However, when I plot something on this axes using the the funcition 'plot3' the axes field 'ButtonDownFcn' is cleared! Of course, nothing happens when later I click with the mouse on the graph. Strangely, this is not the case when I create a graph using 'plot' (I didn't check all the other plotting functions). Why? Is this the way Matlab is suppose to treat axes?
