Tutorial: Creating 100% Stacked Line Charts with ECharts

Overview

A 100% Stacked Line Chart is a great way to visualize relative proportions of different categories over time. Unlike standard line charts, which show absolute values, a 100% stacked line chart displays the percentage contribution of each category, making it easier to compare trends across multiple groups.

A 100% Stacked Line Chart is particularly useful in various scenarios where you want to visualize the relative proportions of different categories over a specific period. Here are some key situations when to use this type of chart:

  1. Market Share Analysis:
    • To show how different brands or products compete in terms of market share over time. This allows for easy comparison of how each entity’s share changes relative to the total market.
  2. Sales Distribution:
    • When analyzing the sales distribution of multiple products across different regions or time periods, helping stakeholders understand which products are gaining or losing traction.
  3. Survey Results:
    • To display survey responses or preferences across different demographics or time frames, showing how opinions shift over time.
  4. Resource Allocation:
    • In project management, to visualize how resources (time, budget, personnel) are allocated among different tasks or projects over a timeline.
  5. Performance Metrics:
    • For tracking key performance indicators (KPIs) across various departments or teams, illustrating how each contributes to the overall performance.
  6. Education and Training:
    • To present student performance across various subjects or courses over time, highlighting shifts in strengths and weaknesses.
  7. Social Trends:
    • To visualize changes in social media engagement, public opinion, or other trends over time, providing insights into how different segments of the population are evolving.

Benefits of Using a 100% Stacked Line Chart

  • Relative Comparison: Easily compare the contributions of different categories without getting bogged down in absolute numbers.
  • Visual Clarity: Provides a clear visual representation of trends and changes, making it easier to communicate insights.
  • Focus on Proportions: Emphasizes how categories interact with one another, which is valuable for strategic decision-making.

Example Scenario

Let’s say we’re analyzing the market share of three smartphone brands (Brand A, Brand B, and Brand C) over five years (2019 to 2023). This will allow us to see how each brand’s market share changes over time, relative to the total market.

Key Concepts

  1. Data Representation: Each line will represent a brand’s market share as a percentage of the total market for each year.
  2. Normalization: The total for each year will sum to 100%, allowing for easy comparison.
  3. Visual Clarity: Using different colors for each brand helps distinguish the lines.

Sample Data

Here’s the market share data for our example:

Year Brand A Brand B Brand C
2019 40% 35% 25%
2020 30% 40% 30%
2021 25% 30% 45%
2022 35% 25% 40%
2023 45% 30% 25%
