Solution

The following example demonstrates how to use the Linear Gradient as such when working with Kendo UI Charts.

    <div id="chart" />
    <script>
      kendo.dataviz.Gradients.series1Gradient = {
        type: "linear",
        stops: [{
          offset: 0,
          color: "#ff4350",
          opacity: 0.5
        }, {
          offset: 1,
          color: "#ff9ea5"
        }]
      };

      kendo.dataviz.Gradients.series2Gradient = {
        type: "linear",
        stops: [{
          offset: 0,
          color: "#00acc1",
          opacity: 0.5
        }, {
          offset: 1,
          color: "#80deea"
        }]
      };

      kendo.dataviz.Gradients.series3Gradient = {
        type: "linear",
        stops: [{
          offset: 0,
          color: "#ffbf46",
          opacity: 0.5
        }, {
          offset: 1,
          color: "#ffd78c"
        }]
      };

      $("#chart").kendoChart({
        title: {
          text: "Site Visitors Stats \n /thousands/"
        },
        legend: {
          visible: false
        },
        seriesDefaults: {
          type: "column",

        },
        series: [{
          name: "Total Visits",
          data: [56000, 63000, 74000, 91000, 117000, 138000],
          overlay: {
            gradient: "series1Gradient",
            start: [0.5, 0],
            end: [0.5, 1]
          },
          border: {
            width: 0
          }
        }, {
          name: "Total Visits",
          data: [86000, 23000, 44000, 21000, 57000, 168000],
          overlay: {
            gradient: "series2Gradient",
            start: [0.5, 0],
            end: [0.5, 1]
          },
        }, {
          name: "Unique visitors",
          data: [52000, 34000, 23000, 48000, 67000, 83000],
          overlay: {
            gradient: "series3Gradient",
            start: [0.5, 0],
            end: [0.5, 1]
          },
        }],         
        categoryAxis: {
          categories: ["Jan", "Feb", "Mar", "Apr", "May", "Jun"],
          majorGridLines: {
            visible: false
          }
        },
        tooltip: {
          visible: true,
          template: "#= series.name #: #= value #"
        }
      });
    </script>
