# Implementing Syncfusion React Sparklines

A comprehensive guide for implementing Syncfusion React Sparkline components - lightweight, compact charts designed to visualize data trends in minimal space without axes or coordinates.

## When to Use This Skill

Use this skill when you need to:
- Create compact data visualizations in dashboards or grids
- Display trend indicators inline with data
- Implement mini charts that consume minimal space
- Show data patterns in table cells or small containers
- Create any of the 5 sparkline types: Line, Column, Area, Win-Loss, or Pie
- Add tooltips, markers, or data labels to sparklines
- Customize sparkline appearance with themes and colors
- Implement accessible, responsive sparkline visualizations
- Integrate sparklines with grids or other components
- Highlight specific data ranges with range bands

## Component Overview

## Quick Start

### Installation

```bash
npm install @syncfusion/ej2-react-charts --save
```

### Basic Sparkline

```javascript
import { SparklineComponent } from '@syncfusion/ej2-react-charts';
import * as React from 'react';
import * as ReactDOM from 'react-dom';

function App() {
  const data = [0, 6, 4, 1, 3, 2, 5];
  
  return (
    <SparklineComponent
      dataSource={data}
      type="Line"
      height="150px"
      width="300px"
    />
  );
}

export default App;
ReactDOM.render(<App />, document.getElementById('charts'));
```

### Sparkline with Tooltip

```javascript
import { SparklineComponent, Inject, SparklineTooltip } from '@syncfusion/ej2-react-charts';
import * as React from 'react';
import * as ReactDOM from 'react-dom';

function App() {
  const data = [0, 6, 4, 1, 3, 2, 5];
  
  return (
    <SparklineComponent
      dataSource={data}
      type="Area"
      height="150px"
      width="300px"
      tooltipSettings={{ visible: true, format: '${x} : ${y}' }}
    >
      <Inject services={[SparklineTooltip]} />
    </SparklineComponent>

      dataSource={data}
      type="Column"
      height="150px"
      width="300px"
      markerSettings={{ visible: ['High', 'Low'] }}
      highPointColor="green"
      lowPointColor="red"
    />
  );
}

export default ColumnSparkline;
ReactDOM.render(<ColumnSparkline />, document.getElementById('charts'));
```

### Win-Loss Sparkline

```javascript
import { SparklineComponent } from '@syncfusion/ej2-react-charts';
import * as React from 'react';
import * as ReactDOM from 'react-dom';

function WinLossSparkline() {
  const data = [12, 15, -10, 13, 15, 6, -12, 17, 13, 0, 8, -10];
  
  return (
    <SparklineComponent
      dataSource={data}
      type="WinLoss"
      height="150px"
      width="300px"
      tiePointColor="blue"
    />
  );
}

export default WinLossSparkline;
ReactDOM.render(<WinLossSparkline />, document.getElementById('charts'));
```
