title: how to plot a text on basemap, python
body: <p>I was thinking to put a text on my map, like <a href="http://www.ncdc.noaa.gov/gibbs/html/GOE-13/IR/2012-07-02-03" rel="noreferrer">the satellite imagery</a>.</p>
  
  <pre><code>import numpy as np, matplotlib.pyplot as plt    
  from mpl_toolkits.basemap import Basemap    
  
  m = Basemap(resolution='l',projection='geos',lon_0=-75.)    
  fig = plt.figure(figsize=(10,8))    
  m.drawcoastlines(linewidth=1.25)    
  x,y = m(-150,80)
  plt.text(x,y,'Jul-24-2012')
  </code></pre>
  
  <p>However, the text "Jul-24-2012" doesn't show up on my figure.
  I guess the reason of this is because the map is not in Cartesian coordinates.</p>
  
  <p>So, could anyone help me to figure out how to do this, please?</p>
