Implement Color-Coded Ranges in Bars

Color ranges can be used to convey additional information—for example, value composition.

This behavior is usually achieved through stacked bar series. However, if you need to convey more flexibility, consider the following Chart.

Color-coded ranges

To implement this functionality, define a series.visual that draws the ranges dynamically. Note that the visual remains in use until the next render event. This allows you to update it asynchronously or in real-time.

The example below demonstrates how to implement color-coded ranges (stripes) in bars when working with Kendo UI Charts.

    <div id="chart" />
      var WIDTH = 5;
      var draw = kendo.drawing;
      var geom = kendo.geometry;

        series: [{
          type: "bar",
          data: [10, 20, 30],
          visual: function(e) {
            var left = e.rect.topLeft();
            var right = e.rect.topRight();
            var bottom = e.rect.bottomLeft();

            var group = new draw.Group();

            for (var x = left.x; x < right.x; x += WIDTH) {
              var rect = new geom.Rect([x, left.y], [WIDTH, e.rect.height()])

              var value = Math.random();
              var path = draw.Path.fromRect(rect, {
                fill: {
                  color: value > 0.5 ? "green" : "lightgreen"
                stroke: null,

                // Custom field
                value: value


            return group;
