Matplotlib Pyplot API
Below is a new untitled notebook with the .ipynb extension (representing an IPython notebook) displayed in a new tab in the browser.
matplotlib.pyplot is a collection of command-style functions that make Matplotlib work like MATLAB. Each Pyplot function will make some changes to the graph. For example, the function creates a graph, a plotting area within a graph, draws some lines within the plotting area, decorates the graph with labels, etc.
