Read the result in context

Minutes are offsets on one continuous axis, not wall-clock dates. Bins show time-weighted means; exact segments expose short gaps that averages can hide. No scheduling or break rules are inferred.

How to use Interval Coverage Heatmap

Explore the worked example. Overlay three team intervals across a working window, inspect hourly averages and locate exact below-target segments.
Replace the coverage intervals with your own entries. Set window start minute, window end minute, bin width · minutes, target coverage units.
Choose “Map interval coverage”. Review coverage bins and exact overlap segments, then compare the visual overview with the detailed tables.
Capture alternative scenarios, download a reusable project and export the selected table or a report when you are ready.

A starting point

Overlay three team intervals across a working window, inspect hourly averages and locate exact below-target segments. The example is illustrative and can be replaced.

Know what you are comparing

Can an hourly average hide a short coverage gap?

Yes. Bins show time-weighted average coverage. The exact overlap-segment table and below-target minute total expose gaps that a bin average may hide.

Files, privacy & saving

Calculations run locally in a browser worker. Input CSV files use the column names in the downloadable template and keep your current settings. Projects restore inputs and up to four scenarios. Imports are limited to 1 MiB and 100 entries. There is no automatic saving. Public pages include advertising and optional analytics; see our privacy policy.

Questions & answers

Can an hourly average hide a short coverage gap?

Yes. Bins show time-weighted average coverage. The exact overlap-segment table and below-target minute total expose gaps that a bin average may hide.

Can I compare and save alternative plans?

Yes. Capture up to four calculated scenarios, restore their inputs and save them in a project JSON file. There is no automatic saving.

How do I bring in my own entries?

Download the CSV template, retain its column names and replace the example rows. Imports are limited to 100 entries and 1 MiB. A saved project also restores settings.

What should I check before using the result?

Minutes are offsets on one continuous axis, not wall-clock dates. Bins show time-weighted means; exact segments expose short gaps that averages can hide. No scheduling or break rules are inferred.
