Stacked bar chart

INFO

Basic data visualization rules are described in the D3 chart.

Description

Stacked bar chart is used to display multiple categories of values and illustrate their proportions relative to the total.

Key points for using stacked bar chart:

  • Choose this chart to compare more than two categories.
  • It's ideal for showing how parts contribute to a whole.
  • Pick distinctly different colors for clarity.
  • Ensure the chart is large enough to easily read the data.

TIP

Bar vs. Histogram Chart

  • Bar charts categorize data qualitatively, showing how different categories compare.
  • Histograms organize data quantitatively, indicating how often values fall within certain ranges.

Appearance

In a stacked bar chart, bars have no gaps between value segments. Select contrasting colors for visibility.

Aim for at least a 20% margin between bars to avoid clutter.
