Fuel Chart Improvements: Smoother Graphs & Accurate Distance Tracking
· 2 min read
We have shipped significant improvements to the fuel consumption chart across both web and mobile platforms.
What Changed
Mobile App — Smoother Fuel Graph
The mobile fuel chart was previously rendering with visual noise when displaying data over multiple days. This has been completely fixed:
- Data downsampling — The chart now intelligently reduces data points to ~500 for smooth rendering while preserving accuracy at refuel/theft event points
- Distance line fix — History data rows with zero cumulative distance no longer cause the distance overlay to drop to zero. The chart now carries forward the last known good distance value
- Per-day chart — Tapping a day in the Fuel Summary report now opens the chart for that specific day, not the entire date range
Web App — Already Smooth
The web app uses ECharts with LTTB sampling and Catmull-Rom interpolation, which already provided smooth rendering. No changes needed on web.
What This Means for You
- Cleaner fuel analysis — No more jagged lines or confusing visual artifacts
- Accurate theft detection — Refuel and drain events are precisely marked
- Better mobile experience — The chart auto-rotates to landscape for detailed viewing
