title: Plotting with rasterio
body: <p>I'm following the example at <a href="https://mapbox.github.io/rasterio/topics/plotting.html" rel="nofollow noreferrer">https://mapbox.github.io/rasterio/topics/plotting.html</a></p>
  
  <p>And am using this geotiff file <a href="http://download.osgeo.org/geotiff/samples/spot/chicago/SP27GTIF.TIF" rel="nofollow noreferrer">http://download.osgeo.org/geotiff/samples/spot/chicago/SP27GTIF.TIF</a></p>
  
  <p>Here is my code:</p>
  
  <pre><code>import rasterio
  from matplotlib import pyplot
  
  tif_file = "SP27GTIF.TIF"
  src = rasterio.open(tif_file)
  pyplot.imshow(src.read(1), cmap='pink')
  pyplot.show = lambda : None  # prevents showing during doctests
  pyplot.show()
  </code></pre>
  
  <p>I run the code and don't get any errors, but I also don't see any plots. Any ideas?</p>
