This tutorial shows both:

A clean long way (easy to understand)

A TRUE one-liner (compressed but still readable)

Perfect for data analysts, Excel users, Python learners, and dashboard creators.

🧠 ✨ Long Way — Step-by-Step Explanation
1️⃣ Create Sample Data

We build a small dataset inside a Pandas DataFrame:

Months

Sales

Then save it to Excel using df.to_excel().

2️⃣ Load Excel Workbook

We use:

from openpyxl import Workbook


to create a clean workbook.

3️⃣ Write Data into the Sheet

We manually append rows:

ws.append(["Month", "Sales"])
ws.append(["Jan", 120])
...


This ensures OpenPyXL has direct control of the cell positions needed for chart references.

4️⃣ Create the Chart

A LineChart() object is created and customized:

chart.title → “Monthly Sales”

Axis titles

Data and category references

We use:

data = Reference(ws, min_col=2, min_row=1, max_row=5)
categories = Reference(ws, min_col=1, min_row=2, max_row=5)

5️⃣ Insert chart into Excel

The chart is placed at:

ws.add_chart(chart, "D2")


Then saved as sales_chart.xlsx.

⚡ ✨ TRUE ONE-LINER Explanation

This one-liner:

Creates a DataFrame

Saves it to Excel

Saves the file

All inside one compressed expression, without using any function definitions unless required.
