Pythesis Plot

Python scientific plotting tool for thesis/dissertation scenarios. Workflow: data upload → analysis → recommendations → confirmation → generation. Triggers when users upload data files (CSV/Excel/TXT) and ask for plots, charts, figures, or data visualization for academic publications.

Python scientific plotting workflow tool supporting the complete process from data upload to figure generation for academic publications.

Workflow

text

[User Uploads Data] → [Auto-save to output dir] → [Data Analysis]
                                           ↓
[Generate Images to output dir] ← [Code Generation] ← [User Confirms Scheme]

Required Steps

1. Data Reception: User uploads data file (txt/md/xlsx/csv)
2. Auto-save: Rename to timestamp-original_filename, save to output/YYYYMMDD-filename/
3. Data Analysis: Analyze dimensions, types, statistical features, column relationships
4. Chart Recommendations: Recommend chart schemes based on data characteristics (type, quantity, layout)
5. User Confirmation: Display analysis report, must wait for user confirmation before generation
6. Generation & Delivery: Python code + chart images, save to same output directory

Core Scripts

1. Main Workflow Script

bash

python scripts/workflow.py --input data.csv --output-dir output/

2. Data Analysis

bash

python scripts/data_analyzer.py --input data.csv

Output: Data characteristics report + chart recommendation scheme

3. Chart Generation

bash

python scripts/plot_generator.py --config plot_config.json --output-dir output/

Naming Conventions

File Type	Naming Format	Example
Data File	{timestamp}-{original}	20250312-145230-data.csv
Analysis Report	analysis_report.md	analysis_report.md
Python Code	{timestamp}_plot.py	20250312-145230_plot.py
Chart PNG	{timestamp}_fig{n}_{type}.png	20250312-145230_fig1_line.png

Usage

Scenario 1: Complete Workflow

When user uploads a data file:

1. Auto-save File

   python

   # Rename and save to output/{timestamp}-{filename}/
   save_uploaded_file(input_file, output_base="output/")
   

2. Execute Data Analysis

   python

   # Analyze data characteristics, generate report
   python scripts/data_analyzer.py --input output/20250312-data/data.csv
   

3. Display Analysis Report to User

   markdown

   ## Data Analysis Report
   
   ### Data Overview
   - File: data.csv
   - Dimensions: 120 rows × 5 columns
   - Types: 3 numeric + 2 categorical columns
   
   ### Column Details
   | Column | Type | Description |
   |-----|------|-----|
   | date | datetime | 2023-01 to 2023-12 |
   | sales | numeric | mean=1250, std=320 |
   | region | categorical | 4 categories: N/S/E/W |
   
   ### Chart Recommendations
   Based on data characteristics, the following schemes are recommended:
   
   **Scheme 1: Time Trend Analysis** ⭐Recommended
   - Chart Type: Line plot
   - Content: Sales trend over time
   - Reason: Time series data, most intuitive for showing trends
   
   **Scheme 2: Regional Comparison**
   - Chart Type: Grouped bar chart
   - Content: Sales comparison across regions
   - Reason: Categorical comparison, suitable for showing differences
   
   **Scheme 3: Comprehensive Dashboard**
   - Chart Type: 2×2 subplot layout
   - Includes: Trend line + Bar chart + Box plot + Correlation heatmap
   - Reason: Rich data dimensions, comprehensive display
   
   Please tell me what you want:
   - "Generate schemes 1 and 2"
   - "Generate all"
   - "Modify scheme 3..." (provide your modification suggestions)
   

4. Wait for User Confirmation ⚠️ Critical Step

   • User may say: "Generate scheme 1" / "Generate all" / "Modify XX..."
   • Must wait for explicit instruction before entering generation phase

5. Generate and Save

   python

   # Generate Python code
   python scripts/plot_generator.py --config plot_config.json
   
   # Output to same directory
   output/20250312-data/
   ├── 20250312-145230_plot.py        # Code
   ├── 20250312-145230_fig1_line.png  # Chart
   └── 20250312-145230_fig2_bar.png
   

Scenario 2: Data Analysis Only

bash

python scripts/data_analyzer.py --input data.csv --output report.md

Scenario 3: Generate from Config

bash

python scripts/plot_generator.py --config config.json --output-dir ./

Chart Recommendation Logic

Data Characteristics	Recommended Chart	Application
Time series + Numeric	Line plot	Trend display
Categorical + Single numeric	Bar chart	Category comparison
Categorical + Distribution	Box/Violin plot	Distribution display
Two numeric (correlated)	Scatter (+regression)	Correlation analysis
Multiple numeric (correlated)	Heatmap	Correlation matrix
Single numeric distribution	Histogram/Density	Distribution characteristics
Multi-dimensional rich data	2×2 subplots	Comprehensive display

Important Notes

1. User confirmation is mandatory: Must wait for user confirmation after analysis, cannot generate directly
2. Unified file management: All output files saved to same output/{timestamp}-{filename}/ directory
3. High-resolution output: Generate PNG at 300 DPI (suitable for publication)
4. Code traceability: Generated Python code also saved to same directory for user modification
5. Academic style: Charts follow top journal standards (Nature/Science/Lancet style)
