Heatmap

Back to Chart types.

Heatmaps visualize magnitude using color across a two-dimensional grid (e.g. day vs hour, product vs region). For a guided maker page with templates, FAQs, and export options, see the heatmap maker.

Data format

Common shapes:

• Triples: [row, col, value]
• Matrix: a 2D matrix with row/column labels (depending on preset)

Import and edit support

• Import: ✅ (CSV / Excel / Paste / Google Sheets)
• Edit: ✅ (heatmap editor, when available)

Customize highlights

• Visual map: color scale, min/max, piecewise vs continuous
• Axes: category labels density and formatting
• Series: label display, item style, emphasis

Tips

• Use an explicit legend (visual map) so readers can decode colors.
• Keep grid size reasonable; very large grids can be hard to read.
