public IActionResult Index()
        {
              List<ColumnChartData> chartData = new List<ColumnChartData>
            {

razor
multi-export.cs
@Html.EJS().Chart("container").Series(series =>
            {
                series.Type(Syncfusion.EJ2.Charts.ChartSeriesType.Column).Width(2)
                .XName("x").YName("yValue").DataSource("ViewBag.dataSource").Name("Germany").Add();

            }).PrimaryXAxis(px => px.ValueType(Syncfusion.EJ2.Charts.ValueType.Category)
             
            ).PrimaryYAxis(py => py.RangePadding(Syncfusion.EJ2.Charts.ChartRangePadding.None)
           ).Title("Inflation - Consumer Price").Tooltip(tt => tt.Enable(true).Header("Temperature")).Render()
    @Html.EJS().Chart("container1").Series(series =>
          {
              series.Type(Syncfusion.EJ2.Charts.ChartSeriesType.Column).Width(2)
              .XName("x").YName("yValue").DataSource("ViewBag.dataSource").Name("Germany").Add();

          }).PrimaryXAxis(px => px.ValueType(Syncfusion.EJ2.Charts.ValueType.Category)

<div>
    @Html.EJS().Button("togglebtn").IsPrimary(true).IconCss("e-icons e-play-icon").Content("Export").CssClass("e-flat").Render()
</div>
<script>
    document.getElementById('togglebtn').onclick = function () {
        var chart = document.getElementById('container').ej2_instances[0];
        var chart1 = document.getElementById('container1').ej2_instances[0];
        chart.export('PNG', 'chart', 'Landscape', [chart, chart1]);
    };
</script>
public IActionResult Index()
        {
              List<ColumnChartData> chartData = new List<ColumnChartData>
            {
                new ColumnChartData { x= "USA", yValue= 46 },
