Size for container

Sparkline can be rendered to its container size. You can set the size through inline or CSS as shown in the following code.

    <div id='container'>
        <div id='element' style="width:650px; height:350px;"></div>
    </div>

//Initialize Sparkline component
var sparklineInstance = new ej.charts.Sparkline({
    dataSource: [
            { x: 0, xval: '2005', yval: 20090440 },
            { x: 1, xval: '2006', yval: 20264080 },
            { x: 2, xval: '2007', yval: 20434180 },
            { x: 3, xval: '2008', yval: 21007310 },
            { x: 4, xval: '2009', yval: 21262640 },
            { x: 5, xval: '2010', yval: 21515750 },
            { x: 6, xval: '2011', yval: 21766710 },
            { x: 7, xval: '2012', yval: 22015580 },
            { x: 8, xval: '2013', yval: 22262500 },
            { x: 9, xval: '2014', yval: 22507620 },
        ],
    // Assign the dataSource values to series of Sparkline 'xName and yName'
    xName: 'xval', yName: 'yval'
});
//Render initialized Sparkline
sparklineInstance.appendTo("#element");

            <div id="element" align="center"></div>
    </div>


<script>
var ele = document.getElementById('container');
if(ele) {
  ele.style.visibility = "visible";
}   
      </script>
<script src="index.js" type="text/javascript"></script>
</body></html>

In percentage

By setting values in percentage, sparkline gets its dimension with respect to its container. For example, when the height is set to ‘50%’, sparkline is rendered to half of its container height.

//Initialize Sparkline component
var sparklineInstance = new ej.charts.Sparkline({
    width: '80%', height: '50%',
    dataSource: [
            { x: 0, xval: '2005', yval: 20090440 },
            { x: 1, xval: '2006', yval: 20264080 },
            { x: 2, xval: '2007', yval: 20434180 },
            { x: 3, xval: '2008', yval: 21007310 },
            { x: 4, xval: '2009', yval: 21262640 },
            { x: 5, xval: '2010', yval: 21515750 },
            { x: 6, xval: '2011', yval: 21766710 },
            { x: 7, xval: '2012', yval: 22015580 },
            { x: 8, xval: '2013', yval: 22262500 },
            { x: 9, xval: '2014', yval: 22507620 },
        ],
    // Assign the dataSource values to series of Sparkline 'xName and yName'
    xName: 'xval', yName: 'yval'
});
//Render initialized Sparkline
sparklineInstance.appendTo("#element");
