Disclosed herein are methods for presenting therapy events on a continuous, time-based data feed. An algorithm for arranging data on the feed can position icons on the feed with information regarding therapy events at a time each event occurred without blocking or interfering with the data feed, including when the data feed is scrolled, zoomed, or otherwise repositioned. The algorithm can include clustering, buffering and affinity components. The clustering component can combine different events occurring at the same time into a single event and keep those events visually together on the data feed. The buffering component can provide a buffer around each event so there is no overlapping of depicted events. The affinity component provides an affinity for placing events as closed to a CGM trend line on the data feed as possible in view of the positioning of other events.
