# Line Chart Default

A single smooth line through six months of values, without point markers.

Line Chart Default is an open-source chart from suiss/ui for React, React Native, SwiftUI and Jetpack Compose. The @esuiss/ui CLI copies its source into your project, so you own the code.

Source: https://ui.suiss.app/docs/charts/line-chart-default

**React**

**Example**

```tsx title="components/charts/line-chart-default.tsx"
"use client"

import { CartesianGrid, Line, LineChart, 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)" },
} satisfies ChartConfig

export function LineChartDefault() {
  return (
    <Card variant="filled" size="sm">
      <CardHeader>
        <CardTitle>Line chart</CardTitle>
        <CardDescription>A smooth curve through each month</CardDescription>
      </CardHeader>
      <CardContent>
        <ChartContainer
          config={chartConfig}
          className="aspect-auto h-48 w-full"
        >
          <LineChart
            accessibilityLayer
            data={chartData}
            margin={{ top: 10, right: 12, left: 12, bottom: 0 }}
          >
            <CartesianGrid vertical={false} strokeDasharray="2 4" />
            <XAxis
              dataKey="month"
              tickLine={false}
              axisLine={false}
              tickMargin={8}
              interval={0}
              tickFormatter={(value: string) => value.slice(0, 3)}
            />
            <ChartTooltip content={<ChartTooltipContent hideLabel />} />
            <Line
              dataKey="desktop"
              type="natural"
              stroke="var(--color-desktop)"
              strokeWidth={2.5}
              dot={false}
            />
          </LineChart>
        </ChartContainer>
      </CardContent>
    </Card>
  )
}
```

The starting line chart: one smooth series without point markers, a month axis and a tooltip. Use it to show a trend over time when the overall shape matters more than individual readings.

## Installation

### CLI

```bash title="Terminal"
npx shadcn@latest add @esuiss/line-chart-default
```

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 line-chart-default
```

### Manual

1. Install the dependencies:

```bash title="Terminal"
npm install 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/line-chart-default.tsx`:

```tsx title="components/charts/line-chart-default.tsx"
"use client"

import { CartesianGrid, Line, LineChart, 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)" },
} satisfies ChartConfig

export function LineChartDefault() {
  return (
    <Card variant="filled" size="sm">
      <CardHeader>
        <CardTitle>Line chart</CardTitle>
        <CardDescription>A smooth curve through each month</CardDescription>
      </CardHeader>
      <CardContent>
        <ChartContainer
          config={chartConfig}
          className="aspect-auto h-48 w-full"
        >
          <LineChart
            accessibilityLayer
            data={chartData}
            margin={{ top: 10, right: 12, left: 12, bottom: 0 }}
          >
            <CartesianGrid vertical={false} strokeDasharray="2 4" />
            <XAxis
              dataKey="month"
              tickLine={false}
              axisLine={false}
              tickMargin={8}
              interval={0}
              tickFormatter={(value: string) => value.slice(0, 3)}
            />
            <ChartTooltip content={<ChartTooltipContent hideLabel />} />
            <Line
              dataKey="desktop"
              type="natural"
              stroke="var(--color-desktop)"
              strokeWidth={2.5}
              dot={false}
            />
          </LineChart>
        </ChartContainer>
      </CardContent>
    </Card>
  )
}
```

4. Update the import paths to match your project.

## Usage

```tsx
import { LineChartDefault } from "@/components/charts/line-chart-default"
```

```tsx
<LineChartDefault />
```

Replace `chartData`, point each `dataKey` at your fields and rename the `chartConfig` entry to set the label and color. Switch the `type` on the line to change the curve, or set `dot` to show markers.

## Notes

Focus the chart and use the arrow keys to step the tooltip through the points.

The baseline line chart inside a `Card`: one series drawn as a natural curve with a month axis, a dashed horizontal grid and a tooltip. There is no value axis.

## Installation

**React Native**

```bash title="Terminal"
npx shadcn@latest add @esuiss-rn/line-chart-default
```

See [Installation](https://ui.suiss.app/docs/installation) for the `components.json` setup. Or use the suiss/ui CLI:

```bash title="Terminal"
npx @esuiss/ui@latest add line-chart-default
```

**SwiftUI**

```bash title="Terminal"
npx @esuiss/ui@latest add line-chart-default --platform swift
```

**Jetpack Compose**

```bash title="Terminal"
npx @esuiss/ui@latest add line-chart-default --platform kotlin
```

The CLI also adds what it builds on: [Card](https://ui.suiss.app/docs/components/card), [Chart](https://ui.suiss.app/docs/components/chart).

4. Update the `com.esuiss.ui` package names to match your project.

## Usage

```tsx
import { LineChartDefault } from "@/components/charts/line-chart-default"
```

```tsx
<LineChartDefault />
```

Replace `chartData` with your records and change each `dataKey` to match your fields. Set the label and color in `chartConfig`, and change the curve with the `type` prop on `Line`. The component takes no props.
