From fd641a8d1767177f00e0542523184beedddd0896 Mon Sep 17 00:00:00 2001 From: Elijah Meeks Date: Thu, 21 May 2026 18:28:02 -0700 Subject: [PATCH 1/3] Improve gauge labels and increase gradient steps Render radial tick marks and reposition gauge labels outside the arc with clock-based alignment and configurable font size; draw 2px-spanning marks and use CSS vars for text styling. Also increase the default gradientSteps from 48 to 240 for smoother gauge gradients and update the test expectation accordingly. --- .../charts/ordinal/GaugeChart.test.tsx | 2 +- src/components/charts/ordinal/GaugeChart.tsx | 58 ++++++++++++++++--- src/components/charts/shared/gaugeGradient.ts | 2 +- 3 files changed, 51 insertions(+), 11 deletions(-) diff --git a/src/components/charts/ordinal/GaugeChart.test.tsx b/src/components/charts/ordinal/GaugeChart.test.tsx index 34474c48..584e468a 100644 --- a/src/components/charts/ordinal/GaugeChart.test.tsx +++ b/src/components/charts/ordinal/GaugeChart.test.tsx @@ -471,7 +471,7 @@ describe("GaugeChart", () => { ) const band = (lastOrdinalFrameProps.data || []).find((d: Datum) => d._gradientBand) - expect(band?._gradientBand?.colors.length).toBeLessThanOrEqual(48) + expect(band?._gradientBand?.colors.length).toBeLessThanOrEqual(240) }) }) }) diff --git a/src/components/charts/ordinal/GaugeChart.tsx b/src/components/charts/ordinal/GaugeChart.tsx index 9168adc1..ee2c2a22 100644 --- a/src/components/charts/ordinal/GaugeChart.tsx +++ b/src/components/charts/ordinal/GaugeChart.tsx @@ -348,20 +348,60 @@ export const GaugeChart = forwardRef(function GaugeChart(props: GaugeChartProps, const labelPct = (ann.value - min) / range const startRad = -Math.PI / 2 + (startAngleDegFinal * Math.PI) / 180 const labelAngle = startRad + labelPct * sweepRad - const labelR = innerRadius - 14 const cx = (context.width || width) / 2 const cy = (context.height || height) / 2 + // Radial tick mark spanning the arc band — 1px past each edge so it + // reads as 2px wider than the arc total. + const markInner = innerRadius - 1 + const markOuter = radius + 1 + const mx1 = Math.cos(labelAngle) * markInner + const my1 = Math.sin(labelAngle) * markInner + const mx2 = Math.cos(labelAngle) * markOuter + const my2 = Math.sin(labelAngle) * markOuter + // Text sits outside the arc.
