Hey all!
This PR reworks the heart rate chart to more closely match the style of Apple Health.
Instead of the previous line/area chart, it now uses a range bar chart that groups readings by the hour, showing the min/max range as a darker bar and the average of that hour as a brighter dot overlaid on top. The header still shows the BPM range and date for the day you're currently viewing, and now fluidly updates when you navigate to a different day.
Since smooth horizontal scrolling requires iOS 17+, I went with a chevron-based day navigation approach instead to keep things compatible with iOS 16. The chart fetches up to a week of data, using the existing weekPredicate in ChartManager, instead of the previously used dayPredicate. Only the data from the current week is fetched, not the last 7 days, similar to how the step chart operates.
The Y axis scales dynamically to the visible data rather than being hardcoded, which I think makes it a lot more readable especially when readings are close together.
Hope you like it 🙂
