Line Chart with Dots

Q: How do I change the size of the dots?

Set r on the dot mark, in pixels: 3 here, plus a 2px strokeWidth in the same color, so each dot reads 4px across the radius. Keep it bigger than the line's own 2px stroke, or the dots disappear into it.

Q: How do I draw hollow dots?

Set the dot mark's fill to var(--background) and keep stroke: "var(--color-desktop)" with a strokeWidth of 2. The card shows through, in light and dark mode.

Q: Can I show the dots only on hover?

Yes. Remove the dot mark and keep the focusRing in chartTooltip(): it draws a dot on the focused point only, the way Recharts' activeDot does. Here it's { radius: 3, strokeWidth: 6 }, a filled dot 6px across the radius; focusRing: true gives a smaller one.

Q: Can the dots be a different color from the line?

Yes. The dot mark has its own fill and stroke, separate from the line's stroke. Point them at another config variable, such as var(--color-mobile), or color each dot by category, as the Line Chart with Colored Dots does.

A smooth line with a filled dot on every month, so each real reading stands out from the curve that joins them, in Solid with TanStack Charts.

About

Pick it when each point is a real measurement and the curve only joins them: monthly snapshots, survey waves, sprint results. The dots show people where the data is, which matters with few points. With dozens of points, drop the dots and mark only the hovered one.

A natural curve through six months with a filled dot on each, in the series color. Hovering marks the active month, and the tooltip shows its value alone.

Usage

import { ChartLineDots } from "@/components/charts/chart-line-dots";

<ChartLineDots />

Customize

Two marks over the same rows: lineY for the curve and a dot mark on x: "month", y: "desktop", wrapped in decorative() so the pointer and the keys read the line's points. Marks paint in array order, so the dots sit on the line.
The dot mark's r: 3 sets the radius, and its fill and 2px stroke take var(--color-desktop).
lineY also has points: true, smaller dots without a second mark. Use the dot mark when you need to size or style them.
chartTooltip({ focusRing: { radius: 3, strokeWidth: 6 } }) draws the active dot on the focused point, filled and 6px across the radius, like Recharts' activeDot={{ r: 6 }}.
ChartContainer's tooltip passes { hideLabel: true }, since the dots already line up with the months.

Should I keep the dots with a lot of data?

Not past a few dozen points. The dots merge into a thick band and hide the line's shape. Keep them for monthly or weekly data; for daily data, mark only the hovered day.

Can the dots be a different color from the line?

Yes. The dot mark has its own fill and stroke, separate from the line's stroke. Point them at another config variable, such as var(--color-mobile), or color each dot by category, as the Line Chart with Colored Dots does.

What does keyboard focus look like?

Tab into the chart and the first month takes focus; the arrow keys move along the dots. The focusRing in chartTooltip() draws the larger active dot on the focused one, so sighted keyboard users can see where they are.

ChartTooltipContent's props (indicator, hideLabel, formatter…) for the default body, or false for TanStack's own tooltip body.

Type: ChartTooltipContentProps | false

renderTooltip?(context: ChartTooltipBodyRenderContext) => JSX.Element

A whole tooltip body of your own, in place of ChartTooltipContent: it gets the focused points (each with its datum, group and color). Read the context's fields in JSX (context.points), so Solid tracks them.

Type: (context: ChartTooltipBodyRenderContext) => JSX.Element

initialWidth?number
