fix(dashboard): modern crisp Storage Growth chart (v5.0.3) - #39
Merged
Conversation
- Root cause of the blurry/distorted graph: preserveAspectRatio="none" stretched the 380-unit viewBox to the card width, non-uniformly scaling strokes and text. - Rewrote renderStorageChart to render at the container's exact pixel size (1 unit = 1px) for crisp output at any width; smooth Catmull-Rom gradient area curve, light gridlines, MB y-axis labels, dated x-axis ticks; tooltip retained. - Updated dashboard-insights.svg + USERGUIDE 15A; SW cache v8. 105 tests pass, lint + headers clean; verified 1:1 crisp rendering in demo.

Fixes the unprofessional resolution/text on the demo dashboard's Storage Growth graph.
Root cause: the chart used
preserveAspectRatio="none", which stretched a fixed 380-unit viewBox to the card width — non-uniformly scaling the line, dots, and text, so everything looked blurry/squished.Fix: the chart now renders at the container's exact pixel size (1 unit = 1px) for crisp output at any width, redesigned as a smooth gradient area chart (Catmull-Rom bezier) with light gridlines, MB y-axis labels, and dated x-axis ticks. The interactive hover/focus tooltip (session, size, delta mode, date) is retained.
Docs:
dashboard-insights.svgmockup + USERGUIDE 15A updated.QA (demo, reloaded): viewBox width == element width (1:1), smooth curve, 10 points, tooltip working, 0 console errors. 105/105 tests pass, lint + headers clean. No co-authors.
