title: Change the text of the offset in a matplotlib plot
body: <p>I want to change the text of the offset in matplotlib. I made a plot:</p>
  
  <pre><code>x = linspace(0, 11, 1000)
  plot(x,2000*(1-exp(-x))+randn(1000))
  axis((10.3, 11, 1996.9, 2002.9))
  </code></pre>
  
  <p><img src="https://i.stack.imgur.com/hvB9N.png" alt="enter image description here"></p>
  
  <p>Than the offset is written in the form +1.996e+3. It seems to me too difficult. I want to change it to +1996, or disable to use offset at all.
  I tried it as follows:</p>
  
  <pre><code>t = gca().yaxis.get_offset_text()
  t.set_text('+1996')
  </code></pre>
  
  <p>It have not worked. What is the right way? Or can I set the format of the offset? Or how can I disable to use offsets?</p>
