We can also use environments such as equation, eqnarray, or align. These features are very useful to scientific users. By combining code cells and Markdown cells, we can create a standalone interactive document that combines computations (code), text, and graphics. 9. IPython also comes with a sophisticated display system that lets us insert rich web elements in the notebook. Here, we show how to add HTML, SVG (Scalable Vector Graphics), and even YouTube videos in a notebook. *float(i) ) for i in range(10)]) + '''''') SVG in the notebook Finally, we display a YouTube video by giving its identifier to YoutubeVideo: In [14]: YouTubeVideo('j9YpkSX7NNM') YouTube in the notebook 10.

We can now display this information in a figure. We first need to reorder the table by the weekday using ix (indexing operation). ylim(0); # Set the bottom axis to 0. 10. 0. We will plot a smoothed version of the track attendance as a function of time (rolling mean). The idea is to compute the mean value in the neighborhood of any day. The larger the neighborhood, the smoother the curve. We will create an interactive slider in the notebook to vary this parameter in real time in the plot. show() 26 Chapter 1 Interactive widget in the notebook There's more...

Let's display some figures. We will plot the daily attendance of two tracks. First, we select the two columns, Berri1 and PierDup. plot() 24 Chapter 1 7. Now, we move to a slightly more advanced analysis. We will look at the attendance of all tracks as a function of the weekday.
