You're almost there, you only need to modify your plot() function and use plot.set_xlim() like so:

...
...
    def plot(self):
        data = [random.random() for i in range(25)]
        plot = self.figure.add_subplot(111)
        plot.plot(data, 'r-')
        plot.set_xlim(left=-10) #<-- added here
        plot.set_title('PyQt Matplotlib Example')
        self.draw()

And it generates this plot:

As you can see, the x-axis has been extended to include negative number starting from -10.
