v4.5.159
Dashboard System Resources card now supports 20 chart visualisation styles with persistent selection
New Feature
1- Dashboard System Resources card: 20 chart styles available (analog gauge, circular ring, horizontal/stacked/vertical bar, sparkline, line/area trend, speedometer, thermometer, big number, heatmap, donut, battery, LED 7-segment digital, wave/liquid fill, dot matrix, bullet chart, conic gradient, half donut). One picker in the card header switches both CPU and RAM gauges simultaneously.
Improvement
1- Chart selection persists in localStorage across browser sessions — the chosen style is restored automatically on next login.
Bug Fixes
2- Apex chart axis labels and tooltips now use a shared percent formatter so values render as "12.5%" instead of "12.500000000001%".
- Battery chart now fills based on remaining headroom (full when load is low, drains as load increases) matching the real-world mental model instead of displaying raw load percentage.
