Why doesn't the tooltip show the month?

hideLabel is on, since the month is already printed under the bar. Remove it from ChartContainer's tooltip prop to show the month above the value.

Bar Chart

Q: How do I change the bar corners?

Set radius on barY: one number rounds every corner, a tuple [topLeft, topRight, bottomRight, bottomLeft] rounds them one by one, and { end: 8 } rounds only the end the value points to. 0 gives square bars.

Q: How do I show the values on the side?

The y scale sets axis: false. Replace it with axis: { line: false, ticks: { size: 0 } } to print the values without tick stubs, and widen the definition's left margin so they fit.

Q: How do I plot my own categories?

Replace chartData with your rows and point x and y at your fields. The band scale keeps the order of the rows, so sort them first if order matters, and rename the desktop entry in chartConfig to your value's key.

Six rounded bars, one per month, for comparing a single series category by category. The base bar chart for Vue, drawn with TanStack Charts.

About

Pick it when people compare separate periods or categories and the heights matter: one month's sales against the next. For the shape of a trend, an area or line chart says more. For two series, the multiple or stacked versions keep them together.

Each month is one bar with 8px rounded corners, over horizontal grid lines. The month labels sit under the bars, cut to three letters, with no axis line and no value axis. The tooltip shows the value without the month.

Usage

<script setup lang="ts">
import ChartBarSimple from "@/components/charts/chart-bar-simple.vue";
</script>

<template>
  <ChartBarSimple />
</template>

Customize

The data is one row per month, { month, desktop }. barY reads x: "month" for the band and y: "desktop" for the height.
fill is var(--color-desktop), from chartConfig.desktop and its var(--chart-1). radius: 8 rounds every corner.
The x scale is a band scale with paddingInner(0.2) and paddingOuter(0.1). Raise the inner padding for thinner bars, or cap them with the mark's maxThickness.
The y scale draws grid: true with axis: false. The x axis keeps its labels with ticks: { size: 0, padding: 10 } and a format that cuts each month to three letters.
ChartContainer's tooltip prop passes { hideLabel: true }, so the tooltip shows the series and value alone.

FAQ

How do I change the bar corners?

Set radius on barY: one number rounds every corner, a tuple [topLeft, topRight, bottomRight, bottomLeft] rounds them one by one, and { end: 8 } rounds only the end the value points to. 0 gives square bars.

How do I make the bars thinner or wider?

Bars fill the band the x scale gives each month, minus its padding. Raise the band scale's paddingInner for more space between them, or set maxThickness on barY to cap their width in pixels as the chart grows.

How do I show the values on the side?

The y scale sets axis: false. Replace it with axis: { line: false, ticks: { size: 0 } } to print the values without tick stubs, and widen the definition's left margin so they fit.

How do I plot my own categories?

Replace chartData with your rows and point x and y at your fields. The band scale keeps the order of the rows, so sort them first if order matters, and rename the desktop entry in chartConfig to your value's key.

Can I use it from the keyboard?

Yes. Tab into the chart, then the arrow keys step from bar to bar and Home and End jump to January and June. The tooltip follows focus and is announced as a live region.
