matplotlib - Showing plots if checkbox is checked, on python (with PyQt4) -

i'm brand new python , i'm trying make first program pyqt4. problem following: have 2 checkboxes (plot1 , plot2), , "end" push button, inside class. when press end, see plots user checks, using matplotlib. i'm not being able that. first idea was:

        self.endbutton.clicked.connect(self.plotandend)         self.plot1checkbox.clicked.connect(self.plot1)         self.plot2checkbox.clicked.conncet(self.plot2)      def plotandend(self)         plot1=self.plot1()         pyplot.show(plot1)         plot2=self.plot2()         pyplot.show(plot2)      def plot1(self)         plot1=pyplot.pie([1,2,5,3,2])         return plot1      def plot2(self)         plot2=pyplot.plot([5,3,5,8,2])         return plot2 

this doesn't work, of course, because "plotandend" plot both figures, regardless of respective checkbox. how can i'm trying to?

wrap plot creation in if statement looks @ state of check boxes. example:

def plotandend(self)     if self.plot1checkbox.ischecked():         plot1=self.plot1()         pyplot.show(plot1)      if self.plot2checkbox.ischecked():         plot2=self.plot2()         pyplot.show(plot2) 

you don't need following lines:

    self.plot1checkbox.clicked.connect(self.plot1)     self.plot2checkbox.clicked.conncet(self.plot2) 

this nothing useful @ moment! qt never uses return value of plotx() methods, , want things happen when click end button, not when click checkbox. plotx() methods useful plotandend() method.
