Quick Start

@{
    var stockData = new[]
    {
        new { x = new DateTime(2023, 1, 1), open = 150, high = 155, low = 145, close = 152, volume = 1000000 },
        new { x = new DateTime(2023, 1, 2), open = 152, high = 158, low = 151, close = 156, volume = 1200000 }
    };
}

<ejs-stockchart id="container">
    <e-stockchart-series-collection>
        <e-stockchart-series dataSource="stockData"
                             xName="x"
                             yName="close"
                             type="Candle">
        </e-stockchart-series>
    </e-stockchart-series-collection>
</ejs-stockchart>

Common Patterns

Pattern 1: Candlestick Chart with DateTime Axis

Create a financial chart showing OHLC (Open, High, Low, Close) data:

<ejs-stockchart id="stockChart">
    <e-stockchart-primaryxaxis 
        valueType="DateTime">
    </e-stockchart-primaryxaxis>
    <e-stockchart-series-collection>
        <e-stockchart-series 
            dataSource="financialData" 
            xName="date" 
            yName="close" 
            type="Candle">
        </e-stockchart-series>
    </e-stockchart-series-collection>
</ejs-stockchart>

Pattern 2: Adding Technical Indicators

Enhance analysis with moving averages:

<ejs-stockchart id="stockChart">
    <e-stockchart-indicators>
        <e-stockchart-indicator 
            type="Ema" 
            field="Close" 
            period="14">
        </e-stockchart-indicator>
    </e-stockchart-indicators>
</ejs-stockchart>

Pattern 3: Interactive Features

Enable crosshairs and tooltips for user interaction:

<ejs-stockchart id="stockChart">
    <e-stockchart-tooltipsettings enable="true"></e-stockchart-tooltipsettings>
    <e-stockchart-crosshairsettings lineType="Vertical">
        <e-crosshairsettings-line color="red"></e-crosshairsettings-line>
    </e-stockchart-crosshairsettings>
</ejs-stockchart>

Pattern 4: Legend Configuration

Position and customize the legend:

<ejs-stockchart id="stockChart">
    <e-stockchart-legendsettings 
        visible="true" 
        position="Bottom" 
        alignment="Center">
    </e-stockchart-legendsettings>
</ejs-stockchart>
