What is a scatter plot maker?
A scatter plot is a chart that uses dots to show the relationship between two numeric variables. Each dot represents one observation: its position on the X axis shows one value, its position on the Y axis shows the other. Patterns across the dots — clusters, outliers, upward or downward drift — reveal correlations and groupings in the data.

How it works
From data to a publication-ready chart in 2 minutes.
- 1
Paste or upload your data
Copy from Excel/Google Sheets and paste into the spreadsheet, or upload a CSV. First two columns become X and Y; an optional third column groups points by colour.
- 2
Style your chart
Pick a colour palette, point shape, axis labels, and optional trend line. All changes preview live as you tweak.
- 3
Add gridlines, legend, and title
Toggle vertical/horizontal gridlines, position the legend, set the chart title and subtitle with custom font size and colour.
- 4
Export your chart
Download as PNG for slides, SVG for publications, or CSV for the raw data. The first export of a session publishes your chart as a public template by default.
Real charts from the community
Every chart you make is shared as a public template so others can remix it. Click any to open it with your own data.
Common questions, direct answers
Plain-language answers to the questions people most often ask about scatter plot makers.
When should I use a scatter plot?
Use a scatter plot when you have two numeric variables and want to see if they're related — for example, study hours vs. exam scores, ad spend vs. revenue, or temperature vs. ice-cream sales. They're the standard chart for correlation, regression, and clustering analysis.
What's the difference between a scatter plot and a bubble chart?
A scatter plot has two dimensions: X and Y. A bubble chart adds a third dimension by varying dot size. Use a scatter plot when only two variables matter; switch to a bubble chart only if the third variable is genuinely meaningful — otherwise it adds noise without information.
How many data points do I need to draw a scatter plot?
At least 2 points to render anything, 20+ for visible patterns, and 50+ for a reliable trend line. With more than ~1,000 points, raw scatter plots can become a dense blob — reduce point opacity, use smaller dots, or switch to a hexbin or density plot.
Can I add a trend line or regression to my scatter plot?
Yes — enable "Show trend line" in the Marks tab. The tool computes an ordinary least-squares linear regression and optionally displays the R² value (how well the line fits). You can fit a single line across all data, or one per group when your third column splits points by category.
Frequently asked questions
Is the scatter plot maker free?+
Yes — 3 graphs per month are free across every tool, with no signup needed to try. Subscribe to Pro for $10/month for unlimited graphs and private templates.
What data format does the scatter plot maker accept?+
Paste directly from Excel or Google Sheets (TSV), or upload a CSV. The first column is your X axis, second column is Y. Add a third column with category labels and the chart auto-colours each group.
Can I add a trend line to my scatter plot?+
Yes — toggle 'Show trend line' in the Marks tab. Choose between a single regression line across all data or one per group, with optional R² value display.
What export formats are available?+
PNG for presentations and slides, SVG for vector publication graphics, and CSV for the underlying data. All exports are at the resolution you see on screen.
Can I make my chart private?+
Every exported chart publishes as a public template by default — others can remix it with their own data. Pro subscribers can toggle private mode before exporting.
