Python Question

I am trying to use IPython notebook on MacOS X with Python 2.7.2 and IPython 1.1.0.

I cannot get matplotlib graphics to show up inline.

`import matplotlib`

import numpy as np

import matplotlib.pyplot as plt

%matplotlib inline

I have also tried

`%pylab inline`

`--pylab=inline`

`x = np.linspace(0, 3*np.pi, 500)`

plt.plot(x, np.sin(x**2))

plt.title('A simple chirp')

plt.show()

Instead of inline graphics, I get this:

`<matplotlib.figure.Figure at 0x110b9c450>`

And

`matplotlib.get_backend()`

`'module://IPython.kernel.zmq.pylab.backend_inline'`

Answer Source

I used `%matplotlib inline`

in the first cell of the notebook and it works. I think you should try:

```
%matplotlib inline
import matplotlib
import numpy as np
import matplotlib.pyplot as plt
```

You can also always start all your IPython kernels in inline mode by default by setting the following config options in your config files:

```
c.IPKernelApp.matplotlib=<CaselessStrEnum>
Default: None
Choices: ['auto', 'gtk', 'gtk3', 'inline', 'nbagg', 'notebook', 'osx', 'qt', 'qt4', 'qt5', 'tk', 'wx']
Configure matplotlib for interactive use with the default matplotlib backend.
```
