[PyQt] problem with figure in pyqt

Hi, I want an application that displays a plot when a 'plot ' button is clicked. My code is given below. The figure window doesnot appear when i run the code. But if there is any error as i hav commented '#plt' the figure window appears. Can someone please tell me why this happens? from PyQt4
