ipython not producing output graph using matplotlib
Question: SO I have recently started trying to use ipython, I am finding I cannot get it
to produce an output graph. I am running the following code in ipython:

    
    
    from sklearn import linear_model
    regr = linear_model.LinearRegression()
    
    regr.fit(x, y)
    pl.plot(x, y, 'o')
    pl.plot(x_test, regr.predict(x_test))
    

and I am recieving the output:

    
    
    [<matplotlib.lines.Line2D at 0x21d453b0>]
    

With no image attatched.

I installed ipython using the pythonxy package. Any thoughts of suggestions on
methods to get plots outputting correctly in ipython

Answer: Try running in a cell:

    
    
    %pylab inline    # or
    %matplotlib inline
    

After that the plots should be displayed inline. Alternatively start the
notebook using the inline option in the command line:

    
    
    ipython notebook --pylab=inline
