Scatter plot

Look for relationships between two numeric metrics by plotting them on an X and Y axis. Create a private, publication-ready scatter plot directly in your browser without transmitting sensitive rows off-device. Data is processed locally on your hardware with zero server uploads, enabling instant export to SVG, PNG, and Excel data.

Edit the data, then export.

Everything runs in your browser. Your data is not uploaded.

Data

Paste tab-separated data from Excel or edit the cells directly.

Paste or import table data

Paste a header row, or choose a local CSV/TSV file. Files are read in this browser and capped at 500 rows.

SVG, PNG, and Excel exports are generated locally in this browser. PowerPoint export is temporarily unavailable while its dependency path is reviewed for a high-severity image parser advisory.

Multi-Variable Correlation & Flow Mechanics

A scatter plot (or XY scatter) maps two continuous quantitative variables onto a Cartesian coordinate system, displaying individual observations as discrete points. It is the fundamental chart type for identifying correlations, clusters, non-linear relationships, and outliers within bivariate data. Trendalyzer processes your scatter plot datasets entirely locally in your browser, guaranteeing complete data privacy with no server uploads.

Coordinate & Matrix Data Structure

Format input columns for scatter plot with explicit headers and numerical measurements. Verify that rows represent discrete categories or observations without unformatted symbol artifacts.

Correlation Traps & Analytical Guidelines

  • Ensure sufficient visual distinction for scatter plot marks across standard and high-contrast viewports.
  • Align text labels horizontally whenever possible to improve cognitive readability for scatter plot elements.
  • Double-check scale boundaries and zero-anchors before exporting scatter plot presentation artwork.

How it works

You edit a table in this page. The renderer draws an SVG from those rows in your browser, then you can download SVG, PNG, or Excel data. The table is not uploaded to any external processing server.

Frequently asked questions

How do you handle heavy overplotting in a scatter plot?

Use point transparency (alpha blending), smaller point radii, or switch to a Hexbin or Contour density plot.
