title: Aitoff projection, Python
body: <p>I'm trying to plot my data with the Aitoff Projection using <code>matplotlib</code></p>
  
  <p>An example is <a href="http://www.google.de/imgres?um=1&amp;hl=en&amp;safe=off&amp;client=ubuntu&amp;sa=N&amp;channel=fs&amp;biw=1276&amp;bih=858&amp;tbm=isch&amp;tbnid=tqfN4bH9sfB6SM%3a&amp;imgrefurl=http://matplotlib.org/examples/pylab_examples/geo_demo.html&amp;docid=5gQzolqaUnPcTM&amp;imgurl=http://matplotlib.org/mpl_examples/pylab_examples/geo_demo.hires.png&amp;w=1100&amp;h=900&amp;ei=8Y9lUebaN4fWsgaNoIDIAQ&amp;zoom=1&amp;iact=rc&amp;dur=408&amp;page=1&amp;tbnh=148&amp;tbnw=173&amp;start=0&amp;ndsp=29&amp;ved=1t:429,r:4,s:0,i:97&amp;tx=126&amp;ty=35" rel="nofollow">here</a>, but I would like to set xaxis limit and visualize only a portion of the sphere. For instance, what should I use to visualize only latitude between 0 and 90 degrees and longitudes between -90 and 90 degrees?</p>
