Use magics to create data graphs

The line magics in this section specialize in rendering data for particular types of data or in conjunction with graphing libraries.

%table

You can use the %table magic command to display dataframe data in table format.

The following example creates a dataframe with two columns and three rows of data, then displays the data in table format.

%matplot

Matplotlib is a comprehensive library for creating static, animated, and interactive visualizations in Python. You can use the %matplot magic command to create a graph after you import the matplotlib library into a notebook cell.

The following example imports the matplotlib library, creates a set of x and y coordinates, and then uses the use the %matplot magic command to create a graph of the points.

import matplotlib.pyplot as plt 
x=[3,4,5,6,7,8,9,10,11,12] 
y= [9,16,25,36,49,64,81,100,121,144] 
plt.plot(x,y) 
%matplot plt

Use the matplotlib and seaborn libraries together

Seaborn is a library for making statistical graphics in Python. It builds on top of matplotlib and integrates closely with pandas (Python data analysis) data structures. You can also use the %matplot magic command to render seaborn data.

The following example uses both the matplotlib and seaborn libraries to create a simple bar graph.

import matplotlib.pyplot as plt 
import seaborn as sns 

x = ['A', 'B', 'C'] 
y = [1, 5, 3] 

sns.barplot(x, y) 
%matplot plt

%plotly

Plotly is an open source graphing library for Python that you can use to make interactive graphs. You use the %ploty magic command to render ploty data.

The following example uses the StringIO, plotly, and pandas libraries on stock price data to create a graph of stock activity from February and March of 2015.
