How to Visualize FormSite 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 FormSite-connected Python applications and scripts for visualizing FormSite data. This article shows how to use the pandas, SQLAlchemy, and Matplotlib built-in functions to connect to FormSite data, execute queries, and visualize the results.
With built-in optimized data processing, the CData Python Connector offers unmatched performance for interacting with live FormSite data in Python. When you issue complex SQL queries from FormSite, the driver pushes supported SQL operations, like filters and aggregations, directly to FormSite and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).
Connecting to FormSite Data
Connecting to FormSite 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 FormSite Profile on disk (e.g. C:\profiles\FormSite.apip). Next, set the ProfileSettings connection property to the connection string for FormSite (see below).
FormSite API Profile Settings
Log into your Formsite account and visit the Admin Portal to generate or retrieve your API key. Your
ServerNumberis the numeric part of your server URL and
UserDirectoryis your account's directory path.
Follow the procedure below to install the required modules and start accessing FormSite 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 FormSite Data in Python
You can now connect with a connection string. Use the create_engine function to create an Engine for working with FormSite data.
engine = create_engine("api:///?Profile=C:\profiles\FormSite.apip&ProfileSettings='APIKey=your_api_key&ServerNumber=your_server_number&UserDirectory=your_user_directory'")
Execute SQL to FormSite
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, Label FROM FormItems WHERE Position = '1'", engine)
Visualize FormSite Data
With the query results stored in a DataFrame, use the plot function to build a chart to display the FormSite data. The show method displays the chart in a new window.
df.plot(kind="bar", x="Id", y="Label") plt.show()
