How to Use
- 1
Choose a starter before editing
Choose Traffic, Budget, Survey or Revenue in Data. Selecting a starter replaces the title, subtitle, categories, values and pie/donut settings, and resets canvas zoom. Start here, then replace all of the sample context with your own.
- 2
Enter one complete set of values
Click each legend label and value to edit it. Use nonnegative numbers in one unit, such as response counts. Add slice inserts a new category with a sample value: replace it before using the graph. Select a slice to edit its value in the toolbar or remove it; at least two categories are retained.
- 3
Check the shares
Choose Percent, Value, Both or None under Slice labels. Shares are calculated from the sum of the values and percentages are rounded to whole numbers. Type measured data rather than dragging it: a rim handle redistributes two neighboring values while preserving their combined total.
- 4
Choose a readable layout
Use a pie or donut, put the legend on the Right or Bottom, and choose a theme and canvas size. A donut can show the total, a custom center label or neither. If every value is zero, the chart shows Total: 0 and No positive values instead of slices; enter a positive value to restore the chart.

Download and inspect the PNG
Download PNG creates a standard-resolution image for free, without signup or a watermark. Open the file and check labels at the size you will use in your document or slide. Canvas zoom changes the on-screen view, not the export dimensions; HD PNG, SVG and video exports require Pro or an active export pass.
Why Choose GraphMake?
Worked example: a fictional class travel survey
These are invented practice data, not results from a real class. Imagine 20 responses to “How did you travel to school today?” with one answer per response: Bus 8, Walk 6, Bike 4 and Car 2. The categories total 20; Bus is 8 ÷ 20 = 40%, Walk 30%, Bike 20% and Car 10%.
Choose Survey before typing. Change the title to “Sample class travel survey” and the subtitle to “Illustrative data: 20 responses, one answer each”. Replace all four starter labels and values with Bus 8, Walk 6, Bike 4 and Car 2. Keep Type set to pie, choose the Studio theme, Both labels, the Right legend and Report size (960 × 620).
Check that the four counts and 40%, 30%, 20% and 10% are visible, then download the PNG. If you switch to donut and choose the Total center, the total should be 20. Changing a measured value changes every calculated share, so keep the original tally alongside the graph and avoid using the rim handles to adjust real survey results.
Choose the whole before drawing the slices
A pie graph shows relative shares of the values you enter. It does not know whether a category is missing, a person was counted twice, or counts and percentages have been mixed. Define the question, time period and unit first. Do not combine, for example, 8 people and 30 percent as if they were the same unit.
Prefer counts when you have the original tally; they avoid ambiguity from already rounded percentages. If you enter percentages, include the complete distribution. Use bar graph maker when the main task is comparing separate category amounts rather than showing one whole.
Prepare the graph for a worksheet or slide
Use a title that names the question and a subtitle that identifies the source or marks invented data as illustrative. Keep category names short enough to read and retain a legend when colors alone would be ambiguous. With many small slices, use fewer meaningful groups only when the underlying data justify grouping, or choose a bar graph.
Canvas choices are Compact (720 × 560), Report (960 × 620), Square (860 × 860) and Slide (1200 × 675). Zoom and Expand help inspect the on-screen canvas; they do not add export resolution. Check the actual PNG for cut-off labels and readable text at the final placement size. Enlarging a standard PNG can make it look soft.
What You Can Create
Class survey counts
Present one answer per response, keep the counts visible and explain how each count becomes a share of the class total.
Fractions and percentages practice
Use the fictional 20-response worked example to connect counts, fractions and percentages, then replace it with your own clearly labelled data.
One budget or time allocation
Show non-overlapping parts of one defined budget or time period. Keep every value in the same unit and include all categories that belong to the total.
Frequently Asked Questions
How are the percentages calculated?
Each share is its value divided by the sum of all values, multiplied by 100. Enter counts or a complete set of percentages without % signs. Entering only 30 and 20 produces 60% and 40%, not 30%, 20% and an automatic remainder. Whole-number rounding can make displayed percentages add up to 99% or 101%; it does not change the entered values.
Which numbers can I type, and what happens to invalid input?
Use complete nonnegative numbers such as 8, 8.25 or 1e3. Do not add currency symbols, commas, % signs or words. Negative, blank, malformed or out-of-range input shows feedback and keeps the latest accepted value. Press Enter or Escape, or leave the field, to restore that value. Rounded or abbreviated values expand to their full stored number when you focus the field.
What happens when a category or the whole total is zero?
A zero category stays in the legend but has no slice area; it shows 0% when other values are positive. If all values are zero, the chart says Total: 0 and No positive values, with dashes for undefined shares and no rim handles. Keep the legend visible to edit the zeros, or turn it back on. Entering a positive value restores the slices; the PNG also shows the empty state when the total is zero.
Does changing the starter keep my data?
No. Traffic, Budget, Survey and Revenue replace the current categories, values, title, subtitle, chart type and center settings, and reset canvas zoom. Choose a starter first. To change only the appearance of your entered data, use the separate Type, Theme, Slice labels, Legend and Size controls.
Can I paste a spreadsheet table here?
This studio has no CSV or spreadsheet-grid paste box; type values into the legend for a small dataset. Google Sheet is a separate linked-data option, not clipboard paste. For a pasted label-and-value table, use the related Graph Maker, select its Pie type and check the imported values before downloading.
When is a pie graph suitable for a class survey?
Use it when each response belongs to one category and the categories cover the same whole. For a question where people can choose several answers, the slices describe shares of selections, not percentages of people. A bar graph is usually clearer for that question, for comparing unrelated amounts, or for categories with very similar values.
Which exports are free?
Creating the graph and downloading a standard PNG are free, without signup or a watermark. HD PNG at 2×, 3× or 4×, SVG and animated video downloads require Pro or an active export pass. Inspect the downloaded image at its intended size before printing or placing it in a document.
Can I reopen and edit the downloaded PNG?
A PNG is a flattened image, not an editable chart document. Use Save while signed in if you want to keep an editable design in your account. Downloading a PNG alone does not create that saved design.
