📝 Walkthrough

Walkthrough

The TrendsChart component has been refactored to simplify its approach to handling estimations for incomplete data periods. A new normalisedDataset is introduced that replaces the final datapoint with an extrapolated value for each series. The previous complex estimation pathway—including dynamic y-axis scaling augmentation and bucket-extrapolation logic—has been removed. The chart now unconditionally uses useNiceScale: true, and the VueUiXy component receives the normalised dataset directly. SVG rendering logic for estimations has been streamlined, including removal of overlay-based estimation indicators. A new extrapolateLastValue() helper function has been added, though its current implementation does not perform actual extrapolation. The net result is a reduction of 219 lines of code.

1346-1350: Update the stale inline comment on useNiceScale.
The note still says monthly/yearly → false, but the flag is now always true, which is misleading.

Proposed fix

-            useNiceScale: true, // daily/weekly -> true, monthly/yearly -> false
+            useNiceScale: true,

Looks amazing! at least from a functionality POV
