Using Kendo Dataviz Vertical Bullet Graph, How to add labels similar to Bar Graph?

Question

Trying to Style up the Bullet Graph to be exactly as Marketing desires. The desired Graph looks like:

How do you add the labels at the top of the bars?

I've tried to set the labels property from the Kendo Documentation:

 labels:
 {
visible: true,
format: "{0}",
font: "14px Arial",
 },

Here is my script that isn't working:

        $barChart = $("#bar-chart").empty();

         $barChart.kendoChart({
            theme: global.app.chartsTheme,
            renderAs: "svg",
            legend: {
                position: "bottom"
            },
            seriesDefaults: {
                type: "column"
            },
            series: [
                {   
                    type: "verticalBullet",
                    currentField: "score",
                    targetField: "average",
                    target: {
                        color: "#444",
                        dashType: "dot",
                        line: {
                          width: 1,
                        }
                    },
                    labels:
                    {
                        visible: true,
                        format: "{0}",
                        font: "14px Arial",
                    },
                    data: [
                       {
                            score: 93.7,
                            average: 65.2,                              
                        }, {
                            score: 80.2,
                            average: 22.2,
                        }, {
                            score: 60.8,
                            average: 35.2,
                        }, {

                            score: 82.1,
                            average: 45.2,                                
                        }, {
                            score: 74.2,
                            average: 55.2,
                        }
                    ]
                }
            ],
            categoryAxis: {
                labels: { rotation: -45 },
                categories: ["Sales & Contracting", "Implementation & Training", "Functionality & Upgrades", "Service & Support", "General"],
                line: {
                    visible: false
                },
                color: "#444", 
                axisCrossingValue: [0, 0, 100, 100]
            },
             tooltip: {
                visible: false
            }
        }).data("kendoChart");

Any help would be greatly appreciated.

Answer 1

Because this is not a supported feature, any attempt to do this is by it's nature a hack. I had a look at kendo demo and noticed that there is a tooltip element with class k-tooltip that contains the total for a bar on mouseover. You should take a look into that mouseover to display the totals.

To recap, bullet charts don't support that type of label you need, and bar charts don't support the visual you need (the special line on the chart).

You could switch back to bar charts and write a custom visual. However, an easier way is to use a plotband on the value axis: https://docs.telerik.com/kendo-ui/api/javascript/dataviz/ui/chart/configuration/valueaxis.plotbands

<div id="chart"></div>
<script>
$("#chart").kendoChart({
  valueAxis:  {
    plotBands: [
      { from: 1, to: 2, color: "red" }
    ]
  },
  series: [
    { data: [1, 2, 3] }
  ]
});
</script>

If you make a very narrow band, it will work pretty. It won't be dotted as in your reference image, and it will be behind the bar, which might be a problem... To go deeper, you would need a custom visual, and it's going to be involved: https://docs.telerik.com/kendo-ui/api/javascript/dataviz/ui/chart/configuration/series.visual

What you're attempting to do is possible. I've created an example on our Try Kendo UI site here: http://trykendoui.telerik.com/@jbristowe/aDIf/7
