How to use the scatter plot
- Select the Scatter toggle at the top of the Chart Maker so it expects "x, y" pairs.
- Paste your data one pair per line — the x value, a comma, then the y value, like "3, 8". Each line becomes one dot.
- Optionally add a title and pick a point color; the plot redraws live and auto-scales both axes as you type.
- Read the shape of the point cloud — an upward or downward diagonal signals a relationship, a shapeless blob signals none.
- Click Download PNG to save your scatter-chart.png — no sign-up, no watermark, nothing uploaded.

Frequently asked questions
- Is this scatter plot maker really free?
- Yes. It is completely free with no sign-up, no trial, and no watermark. You paste your data, get a live scatter chart, and download a PNG. There is no paid tier and no account step.
- How do I enter data for a scatter plot?
- Type one "x, y" pair per line — the x value, a comma, then the y value, like "3, 8" on one line and "5, 14" on the next. Each line becomes one dot. There is no file upload; you paste the numbers as text, and the chart redraws live as you type.
- Can I upload a CSV or Excel file?
- No — this tool does not import CSV or spreadsheet files. It is a paste-your-numbers tool. Copy the two columns you care about and paste them one pair per line. This keeps it instant and keeps your data on your device, since nothing is uploaded.
- Can I plot more than one group or series?
- No. Each chart is a single series — one cloud of dots in one color. There is no grouped or multi-color scatter, and no separate legend for categories. If you need to compare two groups, make two separate PNGs.
- Does it draw a trend line or calculate correlation?
- No. The maker plots your raw points and auto-scales the axes, but it does not add a regression line, R-squared, or a correlation number. You read the relationship visually from the shape of the point cloud. For statistical fitting, use a stats package.
- When should I use a scatter plot instead of a line graph?
- Use a scatter plot when both axes are measured numeric variables and you want to see how they relate — for example ad spend vs. signups. Use the line graph maker instead when your x-axis is time or ordered steps and you want to trace a trend, since a line connects points in sequence while a scatter deliberately does not.
- What format is the download, and is there a watermark?
- You get a clean PNG image (saved as scatter-chart.png) drawn on a canvas — no watermark, no logo, no sign-up. It is a static picture, not an interactive or embeddable SVG, so it is ready to drop into a slide, doc, or post.
- Is my data private?
- Yes. The chart is drawn entirely in your browser on an HTML canvas. Your pasted pairs are never sent to a server or uploaded anywhere — everything happens locally on your device.
