How to Visualize Quickbase 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 Quickbase, the pandas & Matplotlib modules, and the SQLAlchemy toolkit, you can build Quickbase-connected Python applications and scripts for visualizing Quickbase data. This article shows how to use the pandas, SQLAlchemy, and Matplotlib built-in functions to connect to Quickbase data, execute queries, and visualize the results.
With built-in optimized data processing, the CData Python Connector offers unmatched performance for interacting with live Quickbase data in Python. When you issue complex SQL queries from Quickbase, the driver pushes supported SQL operations, like filters and aggregations, directly to Quickbase and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).
Connecting to Quickbase Data
Connecting to Quickbase 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.
User Authentication Method
To authenticate with user credentials, specify the following connection properties:
- Set the User and Password.
- If your application requires an ApplicationToken;, you must provide it otherwise an error will be thrown. You can find the ApplicationToken under SpecificApp > Settings > App management > App properties > Advanced settings > Security options > Manage Application Token.
User Token Authentication
To authenticate with a user token, specify the following connection properties:
- Set UserToken and you are ready to connect. You can find the UserToken under Quick Base > My Preferences > My User Information > Manage User Tokens.
Follow the procedure below to install the required modules and start accessing Quickbase 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 Quickbase Data in Python
You can now connect with a connection string. Use the create_engine function to create an Engine for working with Quickbase data.
engine = create_engine("quickbase:///[email protected]&Password=password&Domain=myinstance.quickbase.com&ApplicationToken=bwkxrb5da2wn57bzfh9xn24")
Execute SQL to Quickbase
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, Column1 FROM SampleTable_1 WHERE Column2 = '100'", engine)
Visualize Quickbase Data
With the query results stored in a DataFrame, use the plot function to build a chart to display the Quickbase data. The show method displays the chart in a new window.
df.plot(kind="bar", x="Id", y="Column1") plt.show()
