Size for Container

Chart can render to its container size. You can set the size via inline or CSS as demonstrated below.

    <div id='container'>
        <div id='element' style="width:650px; height:350px;"></div>
    </div>
var chartData = [
    { month: 'Jan', sales: 35 }, { month: 'Feb', sales: 28 },
    { month: 'Mar', sales: 34 }, { month: 'Apr', sales: 32 },
    { month: 'May', sales: 40 }, { month: 'Jun', sales: 32 },
    { month: 'Jul', sales: 35 }, { month: 'Aug', sales: 55 },
    { month: 'Sep', sales: 38 }, { month: 'Oct', sales: 30 },
    { month: 'Nov', sales: 25 }, { month: 'Dec', sales: 32 }
];
var chart  = new ej.charts.Chart({
  primaryXAxis: {
      valueType: 'Category'
  },
  series:[{
      dataSource: chartData,
      xName: 'month',
      yName: 'sales',
      type: 'Line'
  }],
  // Width and height for chart in pixel
  width: '650', height: '350'
}, '#element');

Size for Chart

You can also set size for chart directly through width and height properties.

In Pixel

You can set the size of chart in pixel as demonstrated below.

var chartData = [
      { month: 'Jan', sales: 35 }, { month: 'Feb', sales: 28 },
      { month: 'Mar', sales: 34 }, { month: 'Apr', sales: 32 },
      { month: 'May', sales: 40 }, { month: 'Jun', sales: 32 },
      { month: 'Jul', sales: 35 }, { month: 'Aug', sales: 55 },
      { month: 'Sep', sales: 38 }, { month: 'Oct', sales: 30 },
      { month: 'Nov', sales: 25 }, { month: 'Dec', sales: 32 }
];
var chart  = new ej.charts.Chart({
    primaryXAxis: {
        valueType: 'Category'
    },
    series:[{
        dataSource: chartData,
        xName: 'month',
        yName: 'sales',
        type: 'Line'
    }],
    // Width and height for chart in pixel
    width: '650', height: '350'
}, '#element');

<body>
    
    <div id="container">
        <div id="element"></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 value in percentage, chart gets its dimension with respect to its container. For example, when the height is ‘50%’, chart renders to half of the container height.

var chartData = [
      { month: 'Jan', sales: 35 }, { month: 'Feb', sales: 28 },
      { month: 'Mar', sales: 34 }, { month: 'Apr', sales: 32 },
      { month: 'May', sales: 40 }, { month: 'Jun', sales: 32 },
      { month: 'Jul', sales: 35 }, { month: 'Aug', sales: 55 },
      { month: 'Sep', sales: 38 }, { month: 'Oct', sales: 30 },
      { month: 'Nov', sales: 25 }, { month: 'Dec', sales: 32 }
];
var chart = new ej.charts.Chart({
    primaryXAxis: {
        valueType: 'Category'
    },
    series:[{
        dataSource: chartData,
        xName: 'month',
        yName: 'sales',
        type: 'Line'
    }],
    // Width and height for chart in percentage
    width: '80%', height: '90%'
}, '#element');

<body>
    
    <div id="container">
        <div id="element"></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>

Note: When you do not specify the size, it takes 450px as the height and window size as its width.
