A line chart with a custom label for Ark UI

A line through the browsers, with a dot on each point and the browser's name from the chart config above it.

One line through the browsers, with a dot on each point. The label above the dot is the browser name from the chart config, not the visitor count.

Use it when each point is a named category, not a date. Long names read more easily in a Table. In React, Ark UI does not look up Chrome and the other names. The demo's formatter reads the config.

FAQ

How do the points say Chrome above them?

LabelList sets dataKey to browser and formatter to formatBrowser. That function looks the key up in chartConfig and returns label, so chrome prints as Chrome. position is top, offset is 12, and fontSize is 12.

How is that label text styled?

LabelList uses className fill-foreground. LineChart sets margin to 24 on the top, left, and right so the names fit. This chart has no XAxis. The browser name is the label above the point.

What is drawn on each point?

Line sets dot to an object whose fill is var(--color-visitors), and activeDot to { r: 6 }. dataKey is visitors, type is natural, stroke is var(--color-visitors), and strokeWidth is 2.

Where does the line color come from?

config gives visitors color var(--chart-2) and the label Visitors. The keys chrome through other have their own colors and labels. formatBrowser uses those labels for the text.

What does the tooltip show?

ChartTooltipContent sets hideLabel, indicator to line, and nameKey to visitors. cursor is false. The row is named Visitors from config.

Can I move along the points with the keyboard?

Yes. LineChart sets accessibilityLayer. CartesianGrid sets vertical to false. The visible names are the LabelList text, and the counts are the visitors values: 275, 200, 187, 173, and 90.
