title: Python axis name in plot
body: <p>can I change a location for signature for axis? like write them on end of axis? and instead of them write another inscription? 
  Now I have 
  <img src="https://i.stack.imgur.com/Wi76I.png" alt="enter image description here"></p>
  
  <p>In code this inscriptions I set</p>
  
  <pre><code>plt.plot(dataX, dataY)
  plt.xlabel('f, Hz')
  plt.ylabel('N')
  plt.savefig(pathForNewGraphDir + "\\" + shortFileName + "_" + str(i) + "_.png")
  </code></pre>
