Grouped Scatter Plot Maker

Compare correlations across groups

A grouped scatter plot adds a third dimension to a scatter chart by coloring each point by category, so you can compare how the relationship between two numeric variables changes across groups. InstaCharts builds it from your spreadsheet with an automatic color legend.

What data you need for a grouped scatter plot

X-Axis Numerical values, the independent variable
Y-Axis Numerical values, the dependent variable
Breakdown A category column; each unique value becomes a color

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

When to use a grouped scatter plot

  • Compare whether a correlation is stronger in one group than another
  • See whether groups occupy distinct regions of the chart
  • Detect outliers within a specific category
  • Test whether a third variable shapes a two-variable relationship

When another chart fits better

  • More than five or six colors get hard to tell apart
  • With only one group, a standard scatter plot is simpler
  • Categorical axes belong in a grouped bar chart

Grouped Scatter Plot maker FAQ

Is the grouped scatter plot maker free?

Yes. You can build and export a grouped scatter plot for free, no sign-up needed. The free tier covers up to 500 rows and adds a watermark, removed on paid plans from $10/month.

How do I color scatter points by category?

Add a breakdown column with the category for each row. InstaCharts assigns each unique value its own color and builds a legend so groups are easy to tell apart.

What data do I need for a grouped scatter plot?

Two numeric columns for the axes plus one category column for the grouping. Both axes must be numeric; for categorical comparisons use a grouped bar chart instead.

How many groups can I show?

You can plot several, but five or six colors is the practical limit for readability. Filter or combine smaller categories to keep the groups distinct.
