When to use this template
This visualization excels at revealing daily patterns, trends, and anomalies in time-series data over extended periods. An analyst would reach for it to quickly identify periods of high or low activity, understand daily habits, or track the consistency of a metric across weeks and months. It makes it easy to spot recurring cycles or unusual spikes/dips that might otherwise be missed in raw tables or line charts.
- Daily time series data with a single quantitative metric.
- Data spanning at least several months, ideally a full year.
- Metrics representing counts, durations, scores, or intensities.
- Identifying daily patterns, anomalies, or recurring cycles.
- Visualizing frequency or accumulation of events over time.
- Comparing daily values across weeks and months.
