Scatter Plot Maker

Find correlations between two variables

A scatter plot places a dot for every row on a two-axis grid, so the pattern of points reveals whether two numeric variables are related and where the outliers sit. InstaCharts is a free scatter plot maker that builds it straight from your spreadsheet.

What data you need for a scatter plot

X-Axis Numerical values, the independent variable
Y-Axis Numerical values, the dependent variable

Paste your spreadsheet, upload a CSV or Excel file, or connect a Google Sheet, and InstaCharts detects your column types and builds the scatter plot automatically.

When to use a scatter plot

  • See whether two numeric variables move together or apart
  • Spot outliers far from the main cluster
  • Explore relationships before statistical modeling
  • Reveal where data points concentrate by density

When another chart fits better

  • A categorical axis belongs in a bar chart
  • Trends over time read better as a line graph
  • Very dense data overplots; add a category or use a heatmap

What data do I need for a scatter plot?

Two numeric columns, one for the X-axis and one for the Y-axis, with each row becoming a point. Paste it in, upload a file, or connect a Google Sheet.

Can I color points by a category?

Yes. Add a breakdown column and InstaCharts turns it into a grouped scatter plot, coloring points by category so you can compare relationships across groups.

Can a scatter plot handle large datasets?

Yes. InstaCharts is built for full spreadsheets, and when points overplot you can filter, color by category, or switch to a heatmap to keep patterns visible.
