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

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

Connecting to Tableau CRM Analytics Data

Connecting to Tableau CRM Analytics 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.

Tableau CRM Analytics uses the OAuth 2 authentication standard. You will need to obtain the OAuthClientId and OAuthClientSecret by registering an app with Tableau CRM Analytics.

See the Getting Started section of the Help documentation for an authentication guide.

Follow the procedure below to install the required modules and start accessing Tableau CRM Analytics 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 Tableau CRM Analytics Data in Python

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

engine = create_engine("tableaucrm:///?OAuthClientId=MyConsumerKey&OAuthClientSecret=MyConsumerSecret&CallbackURL=http://localhost:portNumber&InitiateOAuth=GETANDREFRESH&OAuthSettingsLocation=/PATH/TO/OAuthSettings.txt")

Execute SQL to Tableau CRM Analytics

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

df = pandas.read_sql("SELECT Name, CloseDate FROM Dataset_Opportunity WHERE StageName = 'Closed Won'", engine)

Visualize Tableau CRM Analytics Data

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

df.plot(kind="bar", x="Name", y="CloseDate")
plt.show()
