How to Visualize Bugzilla 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 Python Connector for Bugzilla, the pandas & Matplotlib modules, and the SQLAlchemy toolkit, you can build Bugzilla-connected Python applications and scripts for visualizing Bugzilla data. This article shows how to use the pandas, SQLAlchemy, and Matplotlib built-in functions to connect to Bugzilla data, execute queries, and visualize the results.

With built-in optimized data processing, the CData Python Connector offers unmatched performance for interacting with live Bugzilla data in Python. When you issue complex SQL queries from Bugzilla, the driver pushes supported SQL operations, like filters and aggregations, directly to Bugzilla and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).

Connecting to Bugzilla Data

Connecting to Bugzilla 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.

You can authenticate to your Bugzilla account using two parameters:

• URL: The URL of your Bugzilla developer's page (the Home page).
• ApiKey: API Keys can be generated from the Preferences -> API Keys section of your Bugzilla developer's page.

Follow the procedure below to install the required modules and start accessing Bugzilla 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 Bugzilla Data in Python

You can now connect with a connection string. Use the create_engine function to create an Engine for working with Bugzilla data.

engine = create_engine("bugzilla:///?Url=http://yourdomain/Bugzilla&APIKey=abc123")

Execute SQL to Bugzilla

Use the read_sql function from pandas to execute any SQL statement and store the resultset in a DataFrame.

df = pandas.read_sql("SELECT Id, Summary FROM Bugs WHERE Creator = 'user@domain.com'", engine)

Visualize Bugzilla Data

With the query results stored in a DataFrame, use the plot function to build a chart to display the Bugzilla data. The show method displays the chart in a new window.

df.plot(kind="bar", x="Id", y="Summary")
plt.show()
