ComfyUI-Data-Analysis

ComfyUI-Data-Analysis is a custom module for analyzing data using Pandas and Matplotlib within ComfyUI.

Currently, it supports the following nodes:

Loading CSV as a DataFrame
Selecting a subset of columns from a DataFrame
Selecting a subset of rows from a DataFrame by specifying a filter condition
Sorting a DataFrame by a column
Displaying the content of a DataFrame
Extracting the first part of a DataFrame
Joining two DataFrames (inner, left, right, outer joins)
Outputting statistics of a DataFrame (e.g., standard deviation)
Line plot
Scatter plot
Bar chart

You can connect these nodes to conduct complex analysis in an intuitive graphical way.
You can also use other Comfy custom nodes to fit your needs (e.g., combining images).

These custom nodes aim to make data exploration and analysis more efficient and enjoyable.

Installation

Installation via ComfyUI Manager

Press Manager button on the top menu bar to display ComfyUI Manager Menu.
Click Custom Node Manager.
In the search field, enter Data analysis.
"ComfyUI-Data-Analysis" should be displayed. Select Install.
Restart ComfyUI.
Reload browser page.

Installation via git

Navigate to the custom_nodes directory within your ComfyUI installation.
Run the following command:
```
git clone https://github.com/HowToSD/ComfyUI-Data-Analysis.git
```
This will create a new subdirectory ComfyUI-Data-Analysis.
Rename the folder name from ComfyUI-Data-Analysis to data-analysis. If you skip this, example workflows will not work as those flows use this folder name.
Check if your ComfyUI environment already has pandas and matplotlib. If not, install them using pip.
```
pip install -r requirements.txt
```
Refer to requirements.txt for the right versions.
Start ComfyUI.

Troubleshooting for installation

This package requires pandas and matplotlib that are not

How to Use

You can right-click, select Add Node, go to Data Analysis, and look for the following nodes:

Node Name	Functionality
Pandas Load CSV	Load a CSV file
Pandas Select Columns	Select specific columns from a DataFrame
Pandas Select Rows	Filter rows based on conditions
Pandas Join	Join two DataFrames
Pandas Head	Extract the first few rows
Pandas Show DataFrame	Display DataFrame contents
Pandas Summary	Show DataFrame statistics
Pandas Sort	Sort DataFrame by a column
Pandas To String	Convert DataFrame to a string
MPL Bar Chart	Generate a bar chart
MPL Line Plot	Generate a line plot
MPL Scatter Plot	Generate a scatter plot

A faster way is to double-click the canvas to open the node search dialog.

The examples directory contains workflows that load data from an example dataset included in this package. These workflows should give you a good idea about how to use these nodes.

Notes

To connect the output from a previous Pandas node to another Pandas node, move the wire toward the top-left of the text field.
CSV file path is relative to the ComfyUI installation directory unless you specify the absolute file path.
