Explanation of Change

Part 2 of 2 of the chart spinner fade-in, building on #103684, which sizes each chart from its card width.

Each chart entry point (BarChart, LineChart, PieChart, web and native) now renders inside ChartFrame, which puts ChartReveal inside ChartWidthBox. ChartReveal keeps one spinner up from the chart engine download until the chart body reports through useReportChartLoading that its data and fonts are ready, and the card has been measured. The chart then mounts at opacity 0 under the spinner, waits HOLD_FRAMES (5) frames for Skia's first draw, and fades in. The frames are counted on the UI thread, where native Skia draws, because the JS thread can be busy for seconds after launch. A chart that mounts with everything in memory has no spinner to hold, so it fades in as soon as its card is measured, in place of the spinner #103684 showed there on native.

The spinner box takes the loaded chart's height from utils/chartHeights.ts, and Home's skeleton spinner card matches it.

Important

A chart with angled x-axis labels, or a pie whose legend wraps past one row, makes its card grow as it mounts under the spinner. The spinner box reserves one line of flat labels and one legend row, because the label angle and the row count depend on the data. The spinner stays in place and the card grows below it.

On native, a chart that loads at app start can leave its card blank for a moment between the spinner and the chart. On a cold start, native Skia puts its first frame on screen after the hold has ended and gives no signal to wait for, so the chart appears partway through its fade. Main removes its spinner as soon as the data is ready, so it shows the same blank with no hold covering any of it.

Fixed Issues

$ #103964
PROPOSAL:

Follow-up to #99560

Tests

Preconditions:

  • Account A: an admin of a workspace with a few months of expenses across several categories and merchants, whose Home shows the Insights card with Spend over time.
  • Tests 1 to 4 run on web, in Chrome. Test 5 runs on iOS or Android.
  • For tests 1 and 2, open Chrome DevTools, and in the Network panel set throttling to Slow 4G, leaving Disable cache unticked. Keep DevTools open while testing.

All five tests exercise the change.

1. Home keeps the chart's spinner in place until the chart fades in (Account A, web)

  1. Sign in as Account A.
  2. While the page placeholder shows, note the height of the placeholder card that holds a spinner.
  3. Once the Insights card appears, verify that it is the same height as that placeholder card.
  4. Verify that the spinner does not move within the card until the Spend over time chart fades in, and that the card does not change height when the chart appears.

2. Each chart type fades in without the card jumping (Account A, web)

  1. Open Spend and reload the page, then in Display set Group by to Month and tap Apply. Open Display again, set View to Line, and tap Apply.
  2. Verify that a single spinner shows while the chart loads, and that the chart then fades in without the card changing height. If the x-axis labels sit at an angle, verify instead that the spinner stays in place while the card grows below it.
  3. Switch the chart type to bar, and repeat step 2.
  4. In Display, set Group by to Category and tap Apply, then set View to Pie the same way, and repeat step 2. If the legend wraps past one row, verify instead that the card grows only by the extra rows.

3. A reloaded chart shows the spinner again (Account A, web)

  1. On Home, open the title dropdown on the Insights card and pick an insight you have not opened in this session.
  2. Verify that the card shows a spinner, and that the new chart then fades in.

4. Without WebGL, the error message replaces the spinner (Account A, web)

  1. Quit Chrome, then start it again from Terminal with WebGL turned off: open -a "Google Chrome" --args --disable-webgl
  2. Open Home, signed in as Account A.
  3. Verify that the Insights card shows "Your browser doesn't support WebGL. Please enable it or switch browsers." with no spinner left on screen.

5. On native, only a loading chart shows the spinner (Account A, iOS or Android)

  1. On Spend, use Display as in test 2 step 1 to group by Month with the Bar view, then force quit the app and open it again.
  2. Verify that the chart card shows a spinner that stays in place until the bar chart fades in, and that the card does not change height when the chart appears. The card can be blank for a moment before the chart appears, as noted above.
  3. Repeat test 3 on the device.
  4. In Display, set View to Line and tap Apply, then switch it to Bar and back to Line the same way.
  5. Switch the chart type to bar, then back to line, and verify that each chart fades in with no spinner.
  • Verify that no errors appear in the JS console

Offline tests

N/A: this change only affects how a chart looks while it loads. It makes no requests and writes no Onyx data.

QA Steps

Same as tests.

  • Verify that no errors appear in the JS console

Quick update: this PR got too big to review in one go, so I split it. #103684 is the first part, and it'll be merged first. It has the refactor that sizes each chart from its card's width before the chart mounts.

I'll rebase this branch onto #103684 and force push, so the diff here only shows what's left:

Review

I found no correctness bugs, and all CI checks pass except Check independent approval. I have one optional suggestion.

Suggestion: let touches pass through the spinner overlay during the fade. In ChartReveal.tsx:129, the spinner box stays mounted over the chart after the hold ends. It goes away only when setIsRevealed(true) runs on the JS thread. On native, the JS thread can lag for seconds, as the hold comment notes. During that time the invisible overlay can block taps and hovers on the chart. Setting pointerEvents to none on that Animated.View when isReady fixes this.

What I checked
  • Callers: Every bar, line, and pie entry point (web and native) now renders the chart body under ChartFrame. Removing the in-body spinner and the empty-data return null leaves no other caller without a spinner. VictoryChartRenderer uses SkiaWebChart outside a reveal, so it keeps its old fallback spinner.
  • Heights: X_AXIS_LABEL_MIN_HEIGHT (15) is the floor for the measured flat label height (about 14.2 for 12px labels), so a chart with flat labels matches its loading height. The pie legend row matches Text's default lineHeight (fontSizeNormalHeight). The shouldShowLabels and shouldShowLegend defaults in chartHeights.ts match the chart body defaults.
  • Home skeleton: The spinner card now uses the same padding hook and height as the real Insights card.
  • Styles: pieChartLegendMargin keeps the old value (32).
  • State changes: Reload, unmount, and CanvasKit failure behave as described. The render-phase resets, the frame cancel on cleanup, and ChartUnavailable reporting isDrawnBySkia: false are all covered by the new tests.

P2 Badge Account for persisted Home insights in skeleton height

When an Insights-beta user has persisted Top Spenders, Top Merchants, or Top Categories as the Home insight, Home restores that supporting chart rather than the first line chart; InsightsSectionContent.tsx:100 passes shouldShowGroupLabels={false}, so the bar/pie wrappers reserve only the 250px content height. This unconditional getCartesianChartHeight() reserves 289px instead, making the cold-start skeleton 39px taller than the restored card and causing it to visibly shrink; derive this height from the restored chart or otherwise accommodate the label-free selections.

Useful? React with 👍 / 👎.

The 39px shrink is real, but neither option fits this PR, so the skeleton stays matched to spend over time, the first insight and the one Home falls back to.

Deriving the height from the restored chart isn't possible: the skeleton only shows while the first OpenApp is pending on an empty store (useInFlightRequests.ts:196-199), which means right after sign-in or a cache reset, and sign-out doesn't keep the saved insight (SignInRedirect.ts:56-68). It comes back in the same OpenApp response that removes the skeleton, so while the skeleton is up there's nothing to tell it which chart is coming. Accommodating the label-free charts would mean one height for every Home insight, which changes how the loaded card looks, so it belongs with design rather than in this PR.

🤖 Web test steps verification results: ❌ fail

The line chart rendered correctly the first time. After that, the Spend section, including the plain Expenses list, got stuck on its row-loading skeleton and never recovered, so the bar, pie, and reload checks couldn't run. I don't think this PR causes the stall: the Expenses list renders no chart, and this PR doesn't touch Search data loading. A code review of every chart consumer (Home Insights, the Insights page, and Spend) also found no regressions.

Step Status
Group by Month, View Line: one spinner, then the line chart, with no height jumpRight after Apply, the line chart rendered correctly. It showed Sep and Oct points, a tooltip, 3 expenses, and $243.75 total. On later visits (switching tabs, going to Home and back, resizing, re-applying Display), the area stayed on the generic row skeleton for more than 90 seconds and showed no error. The height-jump check couldn't be judged.

Suggestion: let touches pass through the spinner overlay during the fade. In ChartReveal.tsx:129, the spinner box stays mounted over the chart after the hold ends. It goes away only when setIsRevealed(true) runs on the JS thread. On native, the JS thread can lag for seconds, as the hold comment notes. During that time the invisible overlay can block taps and hovers on the chart. Setting pointerEvents to none on that Animated.View when isReady fixes this.

Not a bug, so no change: on native the overlay can't take a tap or hover from the chart in that window.

It sits at opacity 0 for the whole window, set on the UI thread, and neither native touch path hit-tests a view that transparent: iOS skips anything under alpha 0.01 (RCTViewComponentView.mm:746), and gesture handler on Android, which carries every chart tap and hover, skips anything under 0.1 (GestureHandlerOrchestrator.kt:912). So on native the overlay already behaves as if it had pointerEvents: none, and adding it changes nothing there. The one platform it would change is web, where there's no lag to cover because the UI thread is the JS thread, and where isReady is already true during the hold, so a click on the still-visible spinner would land on the invisible chart.

🤖 Web test steps verification results: ❌ fail

Not caused by this PR: in each failed step Search never got its own content on screen, and the PR doesn't change any Search code.

That includes the blank Top categories area. A chart view always renders inside a card with its title, and that card sits outside the chart code (SearchChartWrapper.tsx:22-27), so a chart that hadn't faded in yet would still leave a titled card behind. The screenshot has no card at all, which means Search never showed its chart view there.

Nothing in the run's artifacts shows a rendered chart, though. The screenshot captioned as the rendered line chart shows the same row skeleton, and the recording ends while the test expenses are still being created, so the chart steps went untested rather than failing.

❌ CONSISTENCY-13 (docs)

This new, non-trivial component file opens straight into a type declaration with no header comment describing its purpose. A one-line header would orient the next reader immediately instead of forcing them to infer from the body that ChartFrame composes ChartWidthBox with ChartReveal and collapses a chart that loads with no data.

Add a short header comment above the first declaration, e.g.:

import type {ReactNode} from 'react';

import React from 'react';

import ChartReveal from './ChartReveal';
import ChartWidthBox from './ChartWidthBox';

/**
 * Wraps a chart in its width box and reveal: measures the card, holds one spinner until the chart is ready, and collapses when it loads with no data.

The spinner overlay is position: absolute with no pointerEvents, and opacity: 0 disables neither hit-testing nor the accessibility tree - so between the fade starting on the UI thread and scheduleOnRN(setIsRevealed, true) landing on JS, it swallows every hover/tap over the chart and keeps shadowing the chart's accessible elements from VoiceOver.

Could you add pointerEvents="none" and hide the overlay from the a11y tree once it's transparent?

<Animated.View
    pointerEvents="none"
    accessibilityElementsHidden={isReady}
    importantForAccessibility={isReady ? 'no-hide-descendants' : 'auto'}
