How to Visualize Beeminder Data in Python with pandas
The rich ecosystem of Python modules lets you get to work quickly and integrate your systems more effectively. With the CData API Driver for Python, the pandas & Matplotlib modules, and the SQLAlchemy toolkit, you can build Beeminder-connected Python applications and scripts for visualizing Beeminder data. This article shows how to use the pandas, SQLAlchemy, and Matplotlib built-in functions to connect to Beeminder data, execute queries, and visualize the results.
With built-in optimized data processing, the CData Python Connector offers unmatched performance for interacting with live Beeminder data in Python. When you issue complex SQL queries from Beeminder, the driver pushes supported SQL operations, like filters and aggregations, directly to Beeminder and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).
Connecting to Beeminder Data
Connecting to Beeminder data looks just like connecting to any relational data source. Create a connection string using the required connection properties. For this article, you will pass the connection string as a parameter to the create_engine function.
Start by setting the Profile connection property to the location of the Beeminder Profile on disk (e.g. C:\profiles\Beeminder.apip). Next, set the ProfileSettings connection property to the connection string for Beeminder (see below).
Beeminder API Profile Settings
Log in to your Beeminder account and navigate to Settings > Account > Personal Auth Token to copy your auth_token value.
Follow the procedure below to install the required modules and start accessing Beeminder through Python objects.
Install Required Modules
Use the pip utility to install the pandas & Matplotlib modules and the SQLAlchemy toolkit:
pip install pandas pip install matplotlib pip install sqlalchemy
Be sure to import the module with the following:
import pandas import matplotlib.pyplot as plt from sqlalchemy import create_engine
Visualize Beeminder Data in Python
You can now connect with a connection string. Use the create_engine function to create an Engine for working with Beeminder data.
engine = create_engine("api:///?Profile=C:\profiles\Beeminder.apip&ProfileSettings='AuthToken=your_auth_token'")
Execute SQL to Beeminder
Use the read_sql function from pandas to execute any SQL statement and store the resultset in a DataFrame.
df = pandas.read_sql("SELECT Slug, Title FROM ArchivedGoals WHERE IsWon = 'true'", engine)
Visualize Beeminder Data
With the query results stored in a DataFrame, use the plot function to build a chart to display the Beeminder data. The show method displays the chart in a new window.
df.plot(kind="bar", x="Slug", y="Title") plt.show()
