Notes

The Kendo UI Chart enables you to display the metadata of a point or a specific part of the axis.

Notes displayed in a chart

Getting Started

The following example demonstrates how to add a note for each series point.

$("#chart").kendoChart({
    dataSource: {
        data: [{
            value: 1,
            noteText: "min"
        },{
            value: 2
        },{
            value: 3,
            noteText: "max"
        }]
    },
    series: [{
        type: "line",
        field: "value",
        noteTextField: "noteText"
    }]
});

You can also add a note to the value axis.

$("#chart").kendoChart({
    series: [{
        data: [1, 2, 3]
    }],
    valueAxis: {
        notes: {
            data: [{
                value: 3,
                label: {
                    text: "max"
                }
            }]
        }
    }
});

Using Templates

To provide better flexibility, define the content of the notes through a template.

The template provides access to all information that is associated with the point:

  • value—The point value. Value dimensions are available as properties, for example, value.x and value.y.
  • category—The category name.
  • series—The data series.
  • (When binding to a data source) dataItem—The original data item.

    $("#chart").kendoChart({ dataSource: { data: [{ value: 1, noteText: "minimum" },{ value: 2 },{ value: 3, noteText: "maximum" }] }, series: [{ type: "line", field: "value", noteTextField: "noteText", notes: { label: { position: "outside", template: "#= dataItem.noteText # of the series" } } }] });

In the axis configuration, you have only value which represents the value of the axis.

$("#chart").kendoChart({
    series: [{
        data: [1, 2, 3]
    }],
    valueAxis: {
        notes: {
            data: [{
                value: 3,
                label: {
                    position: "outside",
                    text: "max",
                    template: "#= value # series value"
                }
            }]
        }
    }
});
