Installation

The emon-tools package offers flexible installation options tailored to various use cases. Depending on your requirements, you can choose to install the complete package or specific subsets of dependencies.

Best Practices for Installation

1. Environment Management: Always use a virtual environment (e.g., venv or conda) to isolate your dependencies and prevent conflicts with other projects.

2. Upgrading Dependencies: Keep your dependencies up to date by running pip install --upgrade emon-tools periodically.

3. Check Requirements: Review the module's requirements in the setup.cfg file or on the PyPI page to ensure compatibility with your system.

Global Installation

To install the entire emon-tools package along with all dependencies, run the following command:

pip install emon-tools["all"]

Included Dependencies:

• aiohttp
• numpy
• pandas
• matplotlib

Tip: This is the best option if you plan to use all features, including data manipulation and visualization.

Module-Specific Installation

You can install specific modules and their dependencies as needed. For example:

• To enable emon_fina module:

pip install emon-tools["fina"]

• To enable pandas time-series output functionality:

pip install emon-tools["fina, time_series"]

• To include graph plotting capabilities:

pip install emon-tools["fina, plot"]

• To enable emon_api module:

pip install emon-tools["api"]

• To enable emon_fina and emon_api modules:

pip install emon-tools["api, fina"]

Modules

emon_tools is modular, allowing you to install and use individual components as needed.

1. emon_fina

The emon_fina module facilitates the analysis and processing of time-series data, particularly from PhpFina file formats.

Features

• Data Reading: Efficiently read data from PhpFina file formats.
• Time-Series Analysis: Compute daily statistics such as min, max, mean, and more.
• Filtering: Validate and filter data based on custom thresholds.
• Utilities: Timestamp manipulation and interval computation tools.

Usage Example

from emon_tools.fina_time_series import FinaDataFrame
from emon_tools.fina_plot import PlotData

fdf = FinaDataFrame(
    feed_id=1,
    data_dir="/path/to/phpfina/files"
)
# Access metadata of the .meta file:
print("Meta: ", fdf.meta)

# get height days of data points from meta start_time
ts = fdf.get_fina_df_time_series(
    start=fdf.meta.start_time,
    step=10,
    window=8 * 24 * 3600
)

PlotData.plot(data=ts)
