Does the tooltip show both series?

Yes. chartTooltip() focuses by month (group-x), so pointing at either bar, or arrowing to a month, lists desktop and mobile together, each with the dashed indicator set by ChartContainer's tooltip prop.

Q: How do I add a third series?

Add tablet to every row, to the fields that fold reads and to chartConfig with var(--chart-3). chartColors picks up its color, and group() makes a third slot in every month.

Desktop and mobile bars side by side in each month, so you compare two series directly at every point. Grouped bars for React with TanStack Charts.

About

Use grouped bars when the question is which series is bigger in each month. When the question is the total and its split, stack them instead. Past three or four series the bars get thin: show one at a time, as the interactive version does.

Each month holds a desktop bar and a mobile bar with 4px corners, in the first two chart colors, over horizontal grid lines. The tooltip lists both values for the month.

Usage

import { ChartBarMultiple } from "@/components/charts/chart-bar-multiple";

<ChartBarMultiple />

Customize

chartData keeps one row per month, { month, desktop, mobile }. fold turns it into a row per month and series, { month, series, visitors }, which barY reads with z: "series".
layout: group() makes a second band scale inside each month, one slot per series. Its paddingInner(0.1) spaces a month's bars; the x scale's paddingInner(0.2) spaces the months.
color: "series" on the mark and color: chartColors(chartConfig) in defineChart paint each series with var(--color-desktop) or var(--color-mobile).
radius: 4 rounds each bar on its own, since grouped bars don't share a stack.
ChartContainer's tooltip prop sets { indicator: "dashed" }, a dashed line in each series' color.

FAQ

Grouped or stacked bars: which should I use?

Grouped, when people compare the series with each other month by month. Stacked, when they read the total and how it splits. The Stacked Bar Chart with Legend draws this data the other way.

How do I add a third series?

Add tablet to every row, to the fields that fold reads and to chartConfig with var(--chart-3). chartColors picks up its color, and group() makes a third slot in every month.

How do I change the space between the bars?

The group's own band scale sets the gap between a month's bars: paddingInner(0.1) in group({ scale }). The x scale's paddingInner(0.2) sets the gap between months.

How do I change which series comes first?

The slots follow the order the series first appear in, which is the order of fold's fields: swap them. Or pass group() a scale instance with its own domain, scaleBand().domain(["mobile", "desktop"]).paddingInner(0.1) (a factory infers one). The first is drawn on the left.

Helpers

ExportType

chartLinearScale?() => LinearScale

A value axis drawn as Recharts draws its default one: zero in the domain, five nice ticks. Pass it as a factory: y: { scale: chartLinearScale }.
