title: Python: Savefig cuts off title
body: <p>Hey I try to savefig my plot, but it allways cuts off my title.
  I think it is because of y=1.05 (to set a distance to the title).
  I can not fix it. Is there a way to save the entire graph?</p>
  
  <pre><code>time=round(t[time_period],0)
  most_sensitive=sorted(most_sensitive)
  plt.figure(figsize=(10, 5))
  plt.suptitle("Scatterplot "+str(name)+" , "+r'$\Delta$'+"Output , Zeit= "+str(time)+" s",fontsize=20,y=1.05)
  figure_colour=["bo","ro","go","yo"]
  for i in [1,2,3,4]:
      ax=plt.subplot(2,2,i)
      plt.plot(parm_value[:,most_sensitive[i-1]], Outputdiff[:,most_sensitive[i-1]],figure_colour[i-1])
      ax.set_xlabel(name+"["+str(most_sensitive[i-1])+"] in "+str(unit))
      ax.set_ylabel(r'$\Delta$'+"Output")
      lb, ub = ax.get_xlim( )
      ax.set_xticks( np.linspace(lb, ub, 4 ) )
      lb, ub = ax.get_ylim( )
      ax.set_yticks( np.linspace(lb, ub, 8 ) )
      ax.grid(True)
  
  
  plt.tight_layout()
  newpath = r'C:/Users/Tim_s/Desktop/Daten/'+str(name)+'/'+str(time)+'/'+'scatterplot'+'/'
  if not os.path.exists(newpath):
      os.makedirs(newpath)
  savefig(newpath+str(name)+'.png')
