Previously the chart rendered nothing at all unless a structured Garmin workout's target was resolved, which meant most activities showed no chart. Now it always shows actual pace/HR over elapsed time (in minutes) for any activity with laps, filled as an area rather than a line, with the expected band layered on top only when available. Each lap's warm-up/effort/recovery/ cool-down phase (from Garmin's per-lap IntensityType) shades the background, with a small legend for whichever phases are present.
