title: Plotting the temperature distribution on a sphere with python
body: <p>I have the following problem:</p>
  
  <p>a have N points on a sphere specified by a array x, with x.shape=(N,3). This array contains their cartesian coordinates. Furthermore, at each point, I have a specified temperature. This quantity is saved in an array T, with T.shape=(N,).</p>
  
  <p>Is there any straight forward way to map this temperature distribution into the plane using different colors? </p>
  
  <p>If it simplifies the task, the position can also be given in polar coordinates (\theta,\phi).</p>
