Read the chart
Read category values, identify the highest and lowest values, calculate a difference and total. Six questions use a shared scale.
Bar graph worksheets
with answers.
Read a bar graph, compare categories, or draw bars from a table. Start with a ready-made PDF, or use your own small dataset to generate a worksheet and a separate worked answer key.

Read the data and questions as text
A class chooses a club · Votes. Labels are equally spaced and stay in the supplied order.
| Label | Votes |
|---|---|
| Art | 12 |
| Chess | 18 |
| Coding | 16 |
| Drama | 16 |
| Music | 10 |
- What value is shown for Art?
- What value is shown for Chess?
- Which label or labels have the highest value?
- Which label or labels have the lowest value?
- What is the difference between the highest and lowest values?
- What is the total across all categories?
3 Download your sheet
Question downloads always hide answers, even when you preview the key. PDFs contain high-resolution page images.
What this worksheet teaches
A bar graph compares values across categories. Each bar starts at zero and its length represents the category value. Read the labelled scale before comparing heights.
Choose a sheet, make it yours, print
- Choose reading, comparison or drawing practice. Reading and comparison have six questions; drawing has three tasks and a labelled blank chart.
- Keep the sample, generate a fresh set, or replace the data. Upload CSV or Excel, or paste spreadsheet cells. Select and check the columns before applying. The questions and worked answers are recalculated from the selected values.
- Preview and download. Print A4 or US Letter at 100%. The PDF has one question page followed by an optional answer-key page. Viewing the key does not add answers to the question page.
Use 3–8 distinct category labels, each up to 18 characters, with one whole-number value from 0 to 100 per category. Choose exactly one value column. Repeated category names are rejected rather than combined.
Three ready-to-print practice packs
Original fictional examples. Each PDF contains one question page and one answer-key page. Download without signing in or enabling JavaScript.
Compare and explain
Compare categories, include ties, calculate differences and explain the zero baseline. Six questions connect calculations to visual interpretation.
Draw the chart
Use a source table to draw bars on a labelled blank grid, then identify the highest value and the range. Three tasks with a completed answer graph.
A worked example with the original values
A class chooses a club · Votes. Art: 12; Chess: 18; Coding: 16; Drama: 16; Music: 10. These are fictional practice values, not findings or benchmarks.
- What value is shown for Art?
- 12 Read Art against the vertical scale.
- What value is shown for Chess?
- 18 Read Chess against the same scale.
- Which label or labels have the highest value?
- Chess The maximum is 18. Include all ties.
Methods and limits
Bars preserve the supplied category order and always include zero. Whole-number tick spacing is selected from 1, 2, 5 or 10 so the printed scale remains readable.
Largest and smallest answers include all tied labels. Differences subtract smaller from larger; the total adds all supplied category values. No missing value becomes zero.
The default data are fictional votes for clubs. For custom datasets, use categories whose values can meaningfully be totalled; a sum of percentages, averages or overlapping groups may not be meaningful.
The graph and worksheet use native Apache ECharts axes and marks. Question and answer exports share the same values and scale. PDF pages contain high-resolution images; use the accessible text view or CSV downloads for selectable values and answers. There is no automated grading or curriculum-certification claim.
Common mistakes to check
- Check whether one grid interval means 1, 2, 5 or 10 units. Counting grid lines alone is not reading a value.
- Equal-height bars are tied; include every tied category when asked for the highest or lowest.
- A zero value is valid and has a zero-height bar. It is different from missing data.
Questions about using these sheets
Can I print only the questions?
Yes. Uncheck “Include a separate answer-key page” before downloading a customized PDF. For ready-made packs, print only page 1. The worksheet SVG also contains questions only.
Can I use my class data?
Yes, within the limits above. Choose “Upload a file” or “Paste data”, select the relevant columns, and review before replacing the current values. The imported data and generated files stay in your browser. Replacing a sample removes its fictional-data label.
Are the answers recalculated when data changes?
Yes. Question values, ties, comparisons and worked answers are derived from the current chart data. Changing paper size preserves the dataset. “Generate fresh data” intentionally replaces it with a new fictional practice set.
Can I share the worksheets?
Yes. Print and share these original worksheets for classroom or home practice, without an account or a watermark across the work. ChartsAI is a free, open-source project by SupaMakers.
