Pie Chart Maker
Paste a label and a value on each line and get a pie chart with every slice sized from your numbers, percentages on the slices and a legend beside them. Slices run clockwise from twelve o'clock in the order you pasted, so the chart tells your story in your sequence rather than a sorted one. Download it as a PNG at 1200×800, 1080×1080 or 1920×1080 pixels, or as an SVG you can edit, in the site's teal palette or a colour-blind-safe set. Nothing is uploaded and no account is needed.
Pie chart. No data yet.
Paste data on the left to draw a chart.
One row per line, the label first, then a comma, a tab or two spaces, then the number. A first line whose second field is not a number is read as a header and used to title the axes. Scatter plots take x, y on each line; box plots take one column of numbers, or a label followed by that series' values. The chart, the title, the size and the palette are remembered in this browser only.
Common questions
- How are the percentages worked out?
- Each slice is its value divided by the sum of every value, so the percentages always add to 100 and the angles to a full circle. The percentage is printed inside any slice that is 5% or more, to one decimal place under 10% and whole numbers above, and the legend on the right lists every slice with its label and percentage to one decimal. The values themselves are not drawn on the chart, but the text description under it carries the first thirty labels with their values and shares, and then how many more there are.
- What happens to very small slices?
- With eight slices or fewer, nothing: every one is drawn, however thin. With more than eight, slices under 3% of the total are folded into a single Other slice, provided there are at least two of them, and if your data already has an Other slice the grouped values join it. The description under the chart names which labels were grouped. To keep every slice separate, keep the list to eight, or combine the small ones yourself under a label of your choosing.
- Can a pie chart show negative or zero values?
- A negative value is refused with an error naming the line, because a slice cannot be less than nothing; a bar chart is the right picture for values that go below zero. A zero value is allowed and simply draws no wedge, though it still appears in the legend at 0.0%. If every value is zero there is nothing to slice and the tool says so.
- How many slices can a pie chart have?
- As many lines as you paste, although a pie stops being readable long before a bar chart does. The legend shows as many entries as fit down the right-hand side at the chosen size, and the six palette colours repeat after six slices, with the last slice shifted so it never matches the first one beside it. Past a dozen or so categories, a bar chart of the same data is easier to read, and switching Type keeps your data.
- Can I change the colours or the labels after downloading?
- In the SVG, yes: every slice, label and legend entry is a separate object, so any vector editor such as Inkscape, Illustrator or Figma can recolour or reword it. The PNG is a flat image at the pixel size you chose. Before downloading, the Palette switch offers the teal ramp or a colour-blind-safe set, and the Title field prints a heading across the top of the chart.
Every mark is drawn from the numbers you paste; nothing is smoothed or estimated. Box plots use the median-of-halves quartile method and the 1.5 IQR outlier rule, both stated on the chart.
