Overview

The Stacked Area Chart Generator allows you to create professional, customizable charts that visualize cumulative trends and the relative contribution of multiple data series over time.

When to Use

  • When you need to visualize how individual components contribute to a total value over a period.
  • When comparing cumulative trends across multiple categories or product lines.
  • When you want to highlight the overall growth or decline of a dataset while maintaining visibility into its sub-parts.

How It Works

  • Input your data in JSON format, specifying labels and multiple series of values.
  • Customize the visual appearance by selecting curve types, adjusting colors, and setting axis labels.
  • Toggle display options like grid lines, data points, or total lines to refine the chart's readability.
  • Generate the chart instantly to visualize your data trends.

Use Cases

Tracking monthly revenue growth broken down by individual product categories.
Visualizing website traffic sources over time to see which channels contribute most to total visits.
Monitoring cumulative resource usage across different departments in a company.

Examples

1. Quarterly Revenue Breakdown

Financial Analyst
Background
An analyst needs to present how three different product lines contributed to the total quarterly revenue.
Problem
It is difficult to see the total growth while simultaneously tracking the performance of each product line.
How to Use
Input the quarterly labels and the revenue data for each product as separate series, then select 'Smooth' curve type.
Example Config
{"labels": ["Q1", "Q2", "Q3", "Q4"], "series": [{"name": "Hardware", "data": [100, 120, 150, 180]}, {"name": "Software", "data": [80, 90, 110, 130]}, {"name": "Services", "data": [50, 60, 70, 80]}]}
Outcome
A smooth stacked area chart clearly showing the total revenue growth and the proportional contribution of Hardware, Software, and Services.

2. Website Traffic Source Analysis

Marketing Manager
Background
The marketing team wants to understand how organic, social, and paid traffic sources have evolved over the last six months.
Problem
Standard line charts overlap, making it hard to see the total traffic volume.
How to Use
Input monthly traffic data for each source and enable the 'Show Total Line' feature.
Example Config
{"labels": ["Jan", "Feb", "Mar", "Apr", "May", "Jun"], "series": [{"name": "Organic", "data": [200, 220, 250, 270, 300, 320]}, {"name": "Social", "data": [50, 60, 80, 70, 90, 100]}, {"name": "Paid", "data": [100, 110, 100, 120, 130, 150]}]}
Outcome
A clear stacked area chart that displays the total traffic trend while highlighting the specific impact of each marketing channel.
