You should therefore label all axes, and in particular, the x-axis should be labeled using dates (See the example image).

| + | |||
| + | 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) | ||
