Scatter Plot Maker
Paste x, y pairs, one per line, and get a scatter plot with round axis steps that cover your data and every point exactly where its numbers put it. No trend line is invented. A first line of words, such as Hours, Score, becomes the axis titles, and a label in front of a pair is printed beside its point. Download it as a PNG at 1200×800, 1080×1080 or 1920×1080 pixels, or as an SVG you can edit, with nothing uploaded and no account.
Scatter plot. 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
- What format do the points need?
- Two numbers per line, x then y, separated by a comma, a tab or two spaces: 2, 61 on one line, 3.5, 68 on the next. A line with only one number, or with a word where a number should be, stops the chart and the error names that line. Negative and decimal values are fine, and a currency or percent sign is dropped.
- How do I title the axes?
- Make the first line a header: two words separated the same way as the numbers, such as Height, Weight. Because its second field is not a number the tool reads it as a header, prints the first word under the horizontal axis and the second above the vertical one, and starts the points from line two.
- Can I label individual points?
- Yes. Put the label first, then the two numbers: Ann, 160, 55. The label is printed beside its dot, to the right when there is room and to the left when the point sits near the edge, and the text description under the chart lists the first thirty labels in full and then how many more there are. Lines without a label draw a plain dot.
- Does it draw a line of best fit?
- No. A fitted line is an estimate, and this tool draws only what you pasted. The plot shows the points on axes that cover them in round steps, so a relationship is visible without a line being imposed. If you need a regression, compute it from the same numbers and note the equation in the title.
- How are the axes chosen?
- Each axis runs from the round tick below the smallest value to the round tick above the largest, in steps of 1, 2 or 5 times a power of ten, so data from 0 to 97 is marked 0, 20, 40, 60, 80, 100. Both axes are worked out the same way, and light grid lines at every tick make positions easy to read.
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.
