    { :  }
  ];

   (
    
  );
}

CSS Styling for Stock Chart

For the Stock Chart period selector UI to work properly, you need to include the required CSS stylesheets in your HTML file. Add the following <link> tags to the <head> section of your index.html:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <link rel="icon" type="image/svg+xml" href="/vite.svg" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    
    <!-- Syncfusion Tailwind CSS for Stock Chart styling -->
    <link href="https://cdn.syncfusion.com/ej2/33.1.44/tailwind3.css" rel="stylesheet" />
    
    <!-- Bootstrap CSS for additional styling support -->
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
    
    <title>Stock Chart App</title>
  </head>
  <body>
    <div id="root"></div>
    <script type="module" =>
  

Key CSS Stylesheets:

1. Syncfusion Tailwind CSS (tailwind3.css) - Required for Stock Chart components

   • Version: 33.1.44 (update to match your Syncfusion version)
   • Provides styling for period selector buttons, range navigator, tooltips, and other UI elements
   • CDN URL: https://cdn.syncfusion.com/ej2/33.1.44/tailwind3.css

2. Bootstrap CSS - Optional but recommended for additional styling support

   • Version: 3.3.7
   • Provides base styling and layout utilities
   • CDN URL: https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css

Important Notes:

• Ensure the Syncfusion CSS version matches your @syncfusion/ej2-react-charts package version
• If you're using a different theme (Material, Bootstrap, Fabric, HighContrast), use the corresponding CSS file from Syncfusion CDN
• Place these stylesheets before other custom stylesheets to allow proper CSS cascade and overrides
• Without these stylesheets, the period selector buttons, tooltips, and other UI elements may not render correctly

Alternative CSS URLs by Theme:

• Material: https://cdn.syncfusion.com/ej2/33.1.44/material.css
• Bootstrap: https://cdn.syncfusion.com/ej2/33.1.44/bootstrap.css
• Fabric: https://cdn.syncfusion.com/ej2/33.1.44/fabric.css

• HighContrast: https://cdn.syncfusion.com/ej2/33.1.44/highcontrast.css

Axis Types Reference

Stock Chart supports multiple axis types for different data scenarios:

DateTime Axis (Default)

Use for date-based stock data:

primaryXAxis={{ 
  valueType: 'DateTime',
  majorGridLines: { width: 0 },
  majorTickLines: { color: 'transparent' }
}}

Best for: Stock price data with dates Inject: DateTime module

DateTimeCategory Axis

Displays only business days (excludes weekends/holidays):

primaryXAxis={{ 
  valueType: 'DateTimeCategory',
  majorGridLines: { width: 0 }
}}

Best for: Business day-only trading data Inject: DateTimeCategory module Note: Requires DateTimeCategory module import and injection

Logarithmic Axis

For Y-axis with logarithmic scale (useful for wide value ranges):

primaryYAxis={{
  valueType: 'Logarithmic',
  labelFormat: '${value}'
}}

Best for: Data spanning multiple orders of magnitude Inject: Logarithmic module Note: Cannot contain zero or negative values

Numeric Axis (Y-axis default)

Standard linear numeric scale:

primaryYAxis={{
  valueType: 'Double',
  labelFormat: '${value}',
  minimum: 0,
  maximum: 500,
  interval: 50
}}

Best for: Price values and general Y-axis No module injection required - This is the default

Multi-Axis Configuration

Use multiple Y-axes for different scales:

<StockChartComponent
  primaryXAxis={{ valueType: 'DateTime' }}
  primaryYAxis={{ title: 'Price', labelFormat: '${value}' }}
>
  {/* Additional axes using StockChartAxesDirective */}
  <StockChartAxesDirective>
    <StockChartAxisDirective
      name='volumeAxis'
      opposedPosition={true}
      title='Volume'
      labelFormat='{value}M'
    />
  </StockChartAxesDirective>
  
  {/* Series bind to respective axes */}
  <StockChartSeriesCollectionDirective>
    <StockChartSeriesDirective type='Candle' yAxisName='primaryYAxis' />
    <StockChartSeriesDirective type='Column' yAxisName='volumeAxis' />
  </StockChartSeriesCollectionDirective>
</StockChartComponent>

Common Patterns
