Currently I try to add three area series within one chart. Two area series should be rendered from top to bottom, and one from bottom to top. In my example "grenze3" should be rendered from bottom to top.

This is my html code:

@{
    ViewBag.Title = "Home Page";
}
 
<div id="example">
 
    <div class="demo-section k-content wide">
        <div id="chart"></div>
    </div>
    <script>
        function createChart() {
            $("#chart").kendoStockChart({
                dataSource: {
                    transport: {
                        read: {
                            url: "../Content/spain-electricity.json",
                            dataType: "json"
                        }
                    },
                    schema: {
                        model: {
                            fields: {
                                year: { type: "date" }
                            }
                        }
                    }
                },
                title: {
                    text: ""
                },
                dateField: "year",
                legend: {
                    visible: true,
                    position: "top"
                },
                seriesDefaults: {
                    type: "line",
                    markers: {
                        visible: false
                    }
                },
                series: [{
                    field: "nuclear",

  }
]

 

In theory plot bands would also work, but from my understanding they do not support different values as you see it in the grenze2 series.
