Hi All,

i am using,
     def draw(self,min,max):
         if not hasattr(self, 'subplot1'):
             self.subplot1 = self.figure.add_subplot(211)
             self.subplot1.grid(True)
             self.subplot2 = self.figure.add_subplot(212)
             self.subplot2.grid(True)
         a,b,c,d,e,f,g = self.compute(min)
         ymin_efg = numpy.real(numpy.amin((e,f,g)))
         ymax_efg = numpy.real(numpy.amax((e,f,g)))
         self.plots2 += self.subplot1.plot(d,a, color='red')
         self.plots2 += self.subplot1.plot(d,a+1, color='green')
         self.plots2 += self.subplot1.plot(d,c+2, color='blue')
         self.plots += self.subplot2.plot(d,numpy.abs(e),color='red')
         self.plots += self.subplot2.plot(d,numpy.abs(f),color='green')
         self.plots += self.subplot2.plot(d,numpy.abs(g),color='blue')
self.subplot1.legend((self.plots[0],self.plots[1],self.plots[2]),('Peak1','Peak2','Peak3'))
         self.subplot2.legend((self.plots[0],self.plots[1],self.plots[2]),
                              ('abs(Wert von Peak1)','abs(Wert von Peak2)',
                               'abs(Wert von Peak3)'))
         self.subplot1.set_ylim([-0.5, 3.5])
         self.subplot2.set_ylim([ymin_efg*1.2, ymax_efg*1.2])

to make some Plots, but my first Point lies on the beginning
of my Plot. How to make some spaces ?

Ok i solved this by making,
self.subplot1.set_xlim(d[0]-abs(d[-1]-d[0])/100,d[-1]+abs(d[-1]-d[0])/100)
self.subplot2.set_xlim(d[0]-abs(d[-1]-d[0])/100,d[-1]+abs(d[-1]-d[0])/100)

This make some more nice Spaces.
