When I add the chart to the page how can I get it to scale to the correct size - the chart is not resizing. I guess I need to set the height?

Hi Alex, 

We have analyzed your query. From that, We would like to let you know that the chart is responsive with respect to the width and height of its parent element, if its zero, then it will render with its default size(600 * 450). we suggest you to use the below workaround solution to achieve your requirement. In that we have refresh the chart once we got the parent size. Based on your requirement we have also prepared a sample using dashboard layout for your reference. Please find below code snippet and sample.   

Code Snippet:  
    protected override async Task OnAfterRenderAsync(bool firstRender)  
        //OnAfterRenderAsync will be triggered after the component rendered.  
        await Task.Delay(500);  
        // refreshing all the chart components to fit within the panel  

If this solution doesn’t meet the requirement, kindly revert us with more information which will be more helpful for further analysis and provide you the solution sooner.

Thanks for the reply.  Not sure the correct attachment was added as it doesn't seem to have any sizing code?

I've added a width and height to the outside div and added the refresh code

and no change.

looks like this, as you can see the chart is still bigger than the div it is placed in

Hi Alex, 

Sorry for the inconvenience. 

We have analyzed your query. From that, we suggest you to use the below workaround solution to achieve your requirement. In which we have provided the required height for parent div and the style of chart has been set to inherit using class name to achieve your requirement. Please find below sample, code snippet and screenshot.  

Code Snippet: 
    .e-chart { 
        height: inherit !important; 
        width: inherit !important; 
<div class="control-section"> 
    <div style="height: 316px; width: 200px"> 
        <EjsChart Title="Inflation - Consumer Price" > 
            <ChartArea><ChartAreaBorder Width="0"></ChartAreaBorder></ChartArea> 
            <ChartPrimaryXAxis ValueType="Syncfusion.EJ2.Blazor.Charts.ValueType.DateTime" LabelFormat="y" IntervalType="IntervalType.Years" EdgeLabelPlacement="EdgeLabelPlacement.Shift"> 
                <ChartAxisMajorGridLines Width="0"></ChartAxisMajorGridLines> 
            <ChartPrimaryYAxis LabelFormat="{value}%" RangePadding="ChartRangePadding.None" Minimum="0" Maximum="100" Interval="20"> 
                <ChartAxisLineStyle Width="0"></ChartAxisLineStyle> 
                <ChartAxisMajorTickLines Width="0"></ChartAxisMajorTickLines> 
            <ChartTooltipSettings Enable="true"></ChartTooltipSettings> 
                <ChartSeries DataSource="@chartData" Name="Germany" XName="xValue" Width="2" 
                             Opacity="1" YName="yValue" Type="ChartSeriesType.Line"> 
                    <ChartMarker Visible="true" Width="10" Height="10"> 
    public class LineChartData 
        public DateTime xValue { get; set; } 
        public double yValue { get; set; } 
        public double yValue1 { get; set; } 
    public List<LineChartData> chartData = new List<LineChartData> 
        new LineChartData { xValue = new DateTime(2005, 01, 01), yValue = 21, yValue1 = 28 }, 
        new LineChartData { xValue = new DateTime(2006, 01, 01), yValue = 24, yValue1 = 44 }, 
        new LineChartData { xValue = new DateTime(2007, 01, 01), yValue = 36, yValue1 = 48 }, 
        new LineChartData { xValue = new DateTime(2008, 01, 01), yValue = 38, yValue1 = 50 }, 
        new LineChartData { xValue = new DateTime(2009, 01, 01), yValue = 54, yValue1 = 66 }, 
        new LineChartData { xValue = new DateTime(2010, 01, 01), yValue = 57, yValue1 = 78 }, 
        new LineChartData { xValue = new DateTime(2011, 01, 01), yValue = 70, yValue1 = 84 },
