How to Visualize Mocean 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 Mocean-connected Python applications and scripts for visualizing Mocean data. This article shows how to use the pandas, SQLAlchemy, and Matplotlib built-in functions to connect to Mocean data, execute queries, and visualize the results.

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

Connecting to Mocean Data

Connecting to Mocean 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.

Using API Key Authentication

Mocean uses API key authentication to control access to the API. To obtain an API Key:

1. Log in to your Mocean account at https://dashboard.moceanapi.com
2. Navigate to your account settings or API credentials section
3. Copy your API Key

After obtaining your API Key, set the following connection properties:

• AuthScheme: Set this to APIKey.

Set the following in the ProfileSettings connection property:

• APIKey: Set this to your Mocean API Key. This is transmitted as a Bearer token in the Authorization header.

Example Connection String

Profile=C:\profiles\Mocean.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key';

Connecting to Mocean

Once the authentication is configured, you can connect to Mocean and query data from any of the available tables such as AccountBalance, AccountPricing, MessageStatus, and NumberLookup.

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

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

engine = create_engine("api:///?Profile=C:\profiles\Mocean.apip&AuthScheme=APIKey&ProfileSettings='APIKey=your_api_key'")

Execute SQL to Mocean

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

df = pandas.read_sql("SELECT ,  FROM AccountBalance WHERE  = ''", engine)

Visualize Mocean Data

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

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