How it works

Categories are assigned rectangular bars whose lengths are proportional to numeric values on a shared axis; grouped or stacked modes change how series occupy each category. Baselines and scale domains determine whether comparisons remain honest.

  • A zero baseline preserves proportional bar length; grouped and stacked layouts answer different questions.

Worked example

Monthly Sales
Generate a bar chart of monthly sales
Input
											Title: Monthly Sales
X axis: Month
Y axis: Revenue ($K)
Labels: ["Jan","Feb","Mar","Apr"]
Data: [45,62,58,71]
Horizontal: false
Output
												xychart-beta
    title "Monthly Sales"
    x-axis ["Jan", "Feb", "Mar", "Apr"]
    y-axis "Revenue ($K)"
    bar [45, 62, 58, 71]

When to use this

Reports, dashboards, and survey summaries use bar charts for category comparisons.

Edge cases

  • A truncated baseline exaggerates small differences.
  • Negative values require bars on both sides of zero.
  • Stacked totals hide individual series comparisons when segments share no baseline.
