About this calculator
A bar graph compares amounts across categories, like books read each day or votes for each choice. Enter your data one line at a time and this bar graph maker draws the chart and reports the highest and lowest bars, the average and the total.
Use it for homework, class surveys, lab results and quick reports. Sort the bars from largest to smallest to make the pattern obvious.
How to use it
- Type one item per line as a label, a comma and a number.
- Add a title and choose how to order the bars.
- Read the graph, the statistics and the data table.
Reading a bar graph
The height of each bar shows its value. Compare bars to see which category is largest or smallest. The range is the highest value minus the lowest value, and the average is the total divided by the number of bars.
Tips for a good bar graph
- Give the graph a clear title.
- Keep labels short.
- Sort bars by size when the order of categories does not matter.
