✨ New Chart Mode: Gauge

A brand-new chart mode — a needle dial per entity, laid out in a column grid. Each entity gets its own dial, so you can mix ranges, colors, and thresholds freely in a single card.

• Arc = the value range seen in the period — it fills from the period minimum → maximum (e.g. a day that ranged 24–30 on a 0–30 dial), not a fill-from-zero bar.
• Needle = the live value (current HA state; falls back to the last data point when there's no live state).
• Dial scale comes from each entity's lower_bound / upper_bound (default 0–100, relabeled Gauge Range → Min / Max in the editor).
• Color thresholds paint the dial — the band and faint background zones follow color_thresholds; enabling Last Color collapses the whole dial to a single color taken from the current value.
• needle_color per entity — threshold, any CSS color, or empty to follow the value color.
• Hover tooltip shows the current value plus the period Peak and Low; gauge_show_minmax labels the two dial ends.

New card options: gauge_columns, gauge_span (90–360°, default 270), gauge_value_position (below / above), gauge_value_size, gauge_show_minmax.

Distinct from the existing show_state: "gauge" state-row display — this is the full chart mode, selectable from the chart-mode dropdown.

🥧 "%" Secondary Value (#260)

Pie, Ranking, and Polar Area now offer a % option for Secondary Value in the state row — it shows each entity's share of the total, matching the percentages drawn on the chart. Set per entity with show_second_state_as: pct (or pick % in the editor's Secondary Value dropdown).

🐛 Bug fixes

• The Date Navigation tab (date picker + Energy date sync) is now available in every chart mode, not just time-based / grid modes — so gauge, pie, ranking, etc. can use date navigation too.

Bug fix for #254

✨ New features

🔦 Period highlight on bar charts

When you hover a bar, the background of that whole period is now shaded, so it is easy to see where each period begins and ends. This is especially helpful with multiple entities drawn side by side, where the small gaps between adjacent periods otherwise make boundaries hard to read.

• New period_highlight option (off by default).
• New period_highlight_color option to set the band color. It accepts any CSS color (hex, rgba, name) or variable; leave it empty for a subtle theme grey. You can also theme it globally with the --sgc-period-highlight-color CSS variable.
• Available in the visual editor (Tooltip section) and in YAML.
• Works whether or not the tooltip itself is enabled.

🚥 Dynamic color thresholds with entity references

Color threshold rows now accept entity references for both the value and the color. Use sensor.x for an entity's state, or sensor.x.attribute for one of its attributes. This lets thresholds follow other sensors (for example a seasonal or dynamic target) instead of being fixed numbers.

template:
  - sensor:
      - name: Seasonal Thresholds
        state: "{{ now().month }}"
        attributes:
          t1: "{{ 12 if now().month in [12,1,2] else 30 if now().month in [6,7,8] else 22 }}"
          t2: "{{ 8  if now().month in [12,1,2] else 25 if now().month in [6,7,8] else 16 }}"
          t3: "{{ 3  if now().month in [12,1,2] else 18 if now().month in [6,7,8] else 10 }}"
          t4: "{{ 0  if now().month in [12,1,2] else 12 if now().month in [6,7,8] else 5  }}"

🎬 Improvements

🌃 Bar chart animation

animate_graph now animates bar charts as well: bars grow up from the baseline when the chart renders. Previously only line charts animated.

🐛 Bug fixes

Line draw-in gaps and 7-day LTS display

Incorrect aggregation with group by date or week

State row value for offset series

Tooltip markers on multi-entity bar charts
