Legend at top with four entries: Historical (green line), Forecast (orange dashed line), 95% CI (fill swatch), 80% CI (fill swatch). Both CI swatches show same orange color in legend. - Data: Historical line is #009E73 brand green — first Okabe-Ito color confirmed. Forecast line is #D55E00 orange (dashed). 95% CI band is light salmon/peach fill (alpha 0.15); 80% CI band is slightly more opaque (alpha 0.25) — visually distinct and readable. Dashed vertical separator at forecast start visible. - Grid: Both x and y major gridlines visible in solid dark ink — slightly more prominent than optimal for a line chart. - Legibility verdict: PASS — all text clearly readable against the warm off-white background. + Background: Warm off-white (#FAF8F1) — correct theme surface + Chrome: Title "timeseries-forecast-uncertainty · r · ggplot2 · anyplot.ai" in dark ink, ~70% plot width. Axis labels "Date" and "Monthly Sales" in dark ink (size=20pt, slightly oversized). Tick labels "$60K/$70K/$80K" and year labels in INK_SOFT (size=16pt). Legend at top: "95% CI", "80% CI", "Historical", "Forecast" — all readable. + Data: Historical line in #009E73 (brand green) from 2022–2024. Dashed forecast line in #D55E00 (vermillion). 95% CI band: very light orange (alpha=0.15). 80% CI band: medium orange (alpha=0.25). Dashed grey vertical line at ~Jan 2025 marking forecast start. CI bands extend to right canvas edge with no padding — minor clipping. + Legibility verdict: PASS (all text readable, minor axis label oversizing) Dark render (plot-dark.png): - Background: Near-black (#1A1A17) — correct dark theme surface. - Chrome: Title in near-white light ink, clearly readable. Axis labels and tick labels in light INK_SOFT — no dark-on-dark failure. Legend text in light ink. All chrome is correctly inverted for dark theme. - Data: Historical line is same #009E73 green — identical to light render (data colors unchanged). Forecast line is same #D55E00 orange. HOWEVER, the CI bands — which were light peach fills in the light render — now appear as dark brownish-red opaque regions due to alpha blending on dark background. At alpha 0.15 and 0.25, #D55E00 on #1A1A17 yields near-solid dark fills with very little differentiation between 80% and 95% CI bands. The forecast line is still legible against the dark CI region. - Grid: Grid lines appear as subtle lighter lines on dark background — acceptable visibility. - Legibility verdict: PASS for chrome legibility (title, labels, ticks all readable). PARTIAL FAIL for CI band visual differentiation — the 80% vs 95% distinction is lost in the dark theme due to insufficient contrast between the two alpha levels on dark background. + Background: Near-black (#1A1A17) — correct dark theme surface, not pure black + Chrome: Title in light #F0EFE8 ink — clearly readable. Axis labels and tick labels in #B8B7B0 (INK_SOFT for dark) — all readable. No dark-on-dark failures. Legend entries readable in light text. + Data: Historical line #009E73 and forecast line #D55E00 are IDENTICAL to light render — only chrome flips. CI bands appear significantly more opaque/heavy on dark background (alpha=0.15/0.25 over #1A1A17 makes orange fills look bold rather than subtle). Same right-edge clipping of CI bands present. + Legibility verdict: PASS (all text readable), but CI band weight imbalance between themes is a design concern — the uncertainty bands dominate the forecast region in dark mode rather than reading as subtle shading. criteria_checklist: visual_quality: - score: 27 + score: 23 max: 30 items: - id: VQ-01 name: Text Legibility - score: 7 + score: 6 max: 8 passed: true - comment: Font sizes explicitly set (title=24, axis.title=20, axis.text=16, - legend.text=16).
