# Tooltip Chart Icons

A stacked bar chart whose tooltip shows an icon for each series in place of a color swatch.

Tooltip Chart Icons is an open-source chart from suiss/ui for React. The @esuiss/ui CLI copies its source into your project, so you own the code.

**Example**

```tsx title="components/charts/tooltip-chart-icons.tsx"
"use client"

import { DesktopIcon, DeviceMobileIcon } from "@phosphor-icons/react"
import { Bar, BarChart, XAxis } from "recharts"

import {
  Card,

    color: "var(--chart-1)",
    icon: () => (
      <DesktopIcon />
    ),

          className="aspect-auto h-52 w-full"
        >
          <BarChart
            accessibilityLayer
            data={chartData}
            margin={{ top: 70, right: 4, left: 4, bottom: 0 }}
          >
            <XAxis

              interval={0}
              tickFormatter={(value: string) => value.slice(0, 3)}
            />
            <ChartTooltip
              defaultIndex={3}
              cursor={false}
              content={<ChartTooltipContent />}
            />
            <Bar

              radius={[0, 0, 4, 4]}
              maxBarSize={30}
            />
            <Bar

              stackId="a"
              fill="var(--color-mobile)"
              radius={[4, 4, 0, 0]}
              maxBarSize={30}
            />
          </BarChart>
        </ChartContainer>
      </CardContent>
    </Card>
  )
}
```

A stacked bar chart whose tooltip shows a small icon for each series instead of a color swatch. Use icons when series map to recognizable things, like device types, and color alone isn't enough to tell them apart.

## Installation

### CLI

```bash title="Terminal"
npx shadcn@latest add @esuiss/tooltip-chart-icons
```

Works in any project with a `components.json`. See [Installation](https://ui.suiss.app/docs/installation#add-components) for the one-line registry setup. Or use the suiss/ui CLI:

```bash title="Terminal"
npx @esuiss/ui@latest add charts tooltip-chart-icons
```

### Manual

1. Install the dependencies:

```bash title="Terminal"
npm install @phosphor-icons/react recharts
```

2. Add the pieces it builds on: [Card](https://ui.suiss.app/docs/components/card), [Chart](https://ui.suiss.app/docs/components/chart).

3. Copy the source into `components/charts/tooltip-chart-icons.tsx`:

```tsx title="components/charts/tooltip-chart-icons.tsx"
"use client"

import { DesktopIcon, DeviceMobileIcon } from "@phosphor-icons/react"
import { Bar, BarChart, XAxis } from "recharts"

import {
  Card,
  CardContent,
  CardDescription,
  CardHeader,
  CardTitle,
} from "@/components/ui/card"
import {
  type ChartConfig,
  ChartContainer,
  ChartTooltip,
  ChartTooltipContent,
} from "@/components/ui/chart"

const chartData = [
  { month: "January", desktop: 186, mobile: 80 },
  { month: "February", desktop: 305, mobile: 200 },
  { month: "March", desktop: 237, mobile: 120 },
  { month: "April", desktop: 173, mobile: 190 },
  { month: "May", desktop: 209, mobile: 130 },
  { month: "June", desktop: 264, mobile: 140 },
]

const chartConfig = {
  desktop: {
    label: "Desktop",
    color: "var(--chart-1)",
    icon: () => (
      <DesktopIcon />
    ),
  },
  mobile: {
    label: "Mobile",
    color: "var(--chart-2)",
    icon: () => (
      <DeviceMobileIcon />
    ),
  },
} satisfies ChartConfig

export function TooltipChartIcons() {
  return (
    <Card variant="filled" size="sm">
      <CardHeader>
        <CardTitle>With icons</CardTitle>
        <CardDescription>An icon instead of a color</CardDescription>
      </CardHeader>
      <CardContent>
        <ChartContainer
          config={chartConfig}
          className="aspect-auto h-52 w-full"
        >
          <BarChart
            accessibilityLayer
            data={chartData}
            margin={{ top: 70, right: 4, left: 4, bottom: 0 }}
          >
            <XAxis
              dataKey="month"
              tickLine={false}
              axisLine={false}
              tickMargin={8}
              interval={0}
              tickFormatter={(value: string) => value.slice(0, 3)}
            />
            <ChartTooltip
              defaultIndex={3}
              cursor={false}
              content={<ChartTooltipContent />}
            />
            <Bar
              dataKey="desktop"
              stackId="a"
              fill="var(--color-desktop)"
              radius={[0, 0, 4, 4]}
              maxBarSize={30}
            />
            <Bar
              dataKey="mobile"
              stackId="a"
              fill="var(--color-mobile)"
              radius={[4, 4, 0, 0]}
              maxBarSize={30}
            />
          </BarChart>
        </ChartContainer>
      </CardContent>
    </Card>
  )
}
```

4. Update the import paths to match your project.

## Usage

```tsx
import { TooltipChartIcons } from "@/components/charts/tooltip-chart-icons"
```

```tsx
<TooltipChartIcons />
```

Add an `icon` component to each series entry in `chartConfig`; the tooltip picks it up automatically. Replace `chartData` and the series keys to match your data.

## Notes

Icons replace the color indicator in every tooltip and legend that uses this config, so add them only where you want them everywhere. The tooltip opens on a preset month when the chart loads.
