A range chart displays data as a band between low and high values. The range bar variant uses horizontal bars, and when combined with a date-time scale it works perfectly for timeline and schedule visualizations.
This custom range bar chart maps the status of two processes across a day using three color-coded series: Active, Idle, and Error. Each bar segment spans a start and end timestamp on a date-time Y-scale with 3-hour tick intervals. Theme-derived colors distinguish the statuses, and tooltips display the From/To times for each segment. A bottom legend identifies the series, with click interaction disabled.
