Qlty Cloud tracks your project’s coverage over time and surfaces it as a chart on the project’s Overview page, under the Coverage tab.

​
What’s plotted

  • Metric: total line coverage percentage for the project’s tracked branch.
  • Time window: the most recent 30 days.
  • Granularity: one data point per day.
The chart redraws automatically as new coverage reports are uploaded — there’s no manual refresh step. If a day has multiple coverage uploads, the most recent value wins; if a day has no upload, that point on the chart is interpolated using the most recent known coverage (so the trend line stays continuous as long as you’ve uploaded at least once).

​
How the data gets there

The Trend chart is based on coverage reports you’ve uploaded for your default branch.
  1. Set up coverage uploads on your default branch.
The Overview’s lens tabs include two more trend lines:
  • Maintainability — technical debt over time.
  • Security — open security findings over time.
All three use the same 30-day window and daily granularity, so switching tabs lets you compare them.
