title: Matplotlib axis not displayed
body: <p>The python code (python 2.7) running on windows 7 shown below results in the following inconsistent behaviour with respect to the display of axis which I do not understand:</p>
  
  <p>1 - a window is opened and a plot without an axis is displayed showing a point
  2 - on closing the window, another window is opened and a plot is displayed showing the same point but this time with an axis. </p>
  
  <pre><code>from osgeo import ogr
  import pylab
  from ospybook.vectorplotter import VectorPlotter
  
  vp = VectorPlotter(False)
  
  myLoc = ogr.Geometry(ogr.wkbPoint)
  
  myLoc.AddPoint(59.5,13)
  vp.plot(myLoc,'rs')
  pylab.show() ## the plot is displayed --without-- axes displayed
  
  myLoc.AddPoint(59.5,13)
  vp.plot(myLoc,'rs')
  pylab.show() ## the plot is displayed with axes displayed
  </code></pre>
  
  <p>Please note that in my environment, if the vector plotter interactive mode is set to True, pylab.show() opens  window but no plot is displayed.</p>
