Bar Graph Maker
Graph Settings
The names for each bar on the X-axis.
The numerical values for each bar on the Y-axis.
How to Use This Bar Graph Maker
Comparing quarterly sales or test scores is easier when bar heights do the talking. Set a graph title, X and Y axis labels, then paste comma-separated category names and matching values—click Draw Graph to render.
Each label needs one numeric value. Use Monospace-friendly lists like Q1, Q2, Q3, Q4 with 12, 19, 3, 5 on the values line.
Bar Graph Maker Formulas and Practical Applications
Bar height scales with value relative to the tallest bar on the chart—think of rows of lockers where taller lockers hold bigger numbers.
Bar Height ∝ Value (linear scale on Y-axis)
Example: values 12, 19, 3, 5—the 19 bar renders at full chart height; others scale proportionally.

Frequently Asked Questions
Why does Draw Graph show an error?
Labels and values must be the same count, and every value must parse as a number. Remove extra commas or empty slots.
Can I use decimal values?
Yes. Decimals such as 12.5 or 0.75 work on the values line.
How do I save the graph?
Screenshot the canvas or use browser tools to save the image after drawing—data never leaves your device.
