| - | When using an ipython notebook, it's nice to make your plots show up inline. To do this, add the following lines to the first cell of your notebook: | ||
| - | |||
| - | <code python> | ||
| - | |||
| - | # this tells seaborn and matplotlib to generate plots inline in the notebook | ||
| - | %matplotlib inline | ||
| - | |||
| - | # these two lines allow you to control the figure size | ||
| - | %pylab inline | ||
| - | pylab.rcParams['figure.figsize'] = (16.0, 8.0) | ||
