## Best for

Social channels compared as lines on one metric at a time, with previous-period ghosts and a per-channel totals table

## Agent notes

- Replace `spanTallies` in social-view.ts with your hourly or daily ledger; `rowsOf` and `summariesOf` bucket it for the plot, table and exports
- A new channel needs a key in `CHANNELS`, a `chartConfig` entry and its classes in `SERIES_TONE`, `BAR_TONE` and `SPOTLIGHT`
- `refresh` only waits `REFRESH_MS` and bumps `revision`, which redraws the lines and the `updated` stamp; wire it to refetch your analytics

## When not to use

- One metric's trend with KPI tiles switching what the plot shows: use [Metric Switcher](https://web.dev.reui.io/blocks/chart/line-chart/chart-6.md) (`get_block("chart-6")`)
- Revenue split into streams against a dashed baseline: use [Revenue Trend](https://web.dev.reui.io/blocks/chart/line-chart/chart-22.md) (`get_block("chart-22")`)

## About Line Chart blocks

### When to use

- A balance, price or revenue trend as a single stroke with period tabs and a peak marker
- Several platforms or channels compared as separate strokes on one time axis
- Two measures on different scales plotted against left and right axes

### When not to use

- A trend that needs its volume emphasized with a filled region below it: use the [Area Chart blocks](https://web.dev.reui.io/blocks/chart/area-chart.md)
- Compact tiles where each figure carries a small trend of its own: use the [Sparkline blocks](https://web.dev.reui.io/blocks/chart/sparkline.md)

### Agent notes

- Series colors live in the `ChartContainer` config; chart-6 and chart-26 plot in a `ComposedChart` with an `Area`, the others in a `LineChart`
