Adding Label Collection

Label collection can be directly added to the scales option within the PivotGauge widget as an array.

JAVASCRIPT

<div ng-controller="PivotGaugeCtrl">
    <div id="PivotGauge1" ej-pivotgauge e-scales="scales" />
</div>
<script>
    var scale= [{
        //..
        labels: [{
            angle: 20
        }]
    }];
    angular.module('PivotGaugeApp', ['ejangular']).controller('PivotGaugeCtrl', function ($scope) {
        //..
        $scope.scales = scale;
    });
</script>

Appearance Customization

The appearance of the Label can be customized through the following properties.

• angle – used to display labels in a rotated manner. By default, the value is 0.
• color – displays the label in specified color.
• opacity – sets the opacity of the label. By default, the value is 1.
• type – indicates the label for major intervals or minor intervals. By default, it takes major intervals.
• includeFirstValue – includes the initial value based on user requirement. By default, the value is “true”.
• font – sets the font size, font style and font family of the label.

JAVASCRIPT

<script>
    var scale= [{
        //..
        labels: [{
            //customizing major labels
            type: "major",
            color: "#1AFF01",
            opacity: 0.8,
            includeFirstValue: false,
            font: {
                size: "15px",
                fontFamily: "Arial",
                fontStyle: "bold"
            }
        },{
            //customizing minor labels
            type: "minor",
            color: "#FF103F",
            opacity: 0.8,
            includeFirstValue: true,
            font: {
                size: "10px",
                fontFamily: "Arial",
                fontStyle: "normal"
            }
        }]
    }];
    angular.module('PivotGaugeApp', ['ejangular']).controller('PivotGaugeCtrl', function ($scope) {
        //..
        $scope.scales = scale;
    });
</script>

Unit Text

The unitText property is used to add some text along with the labels. Normally, we indicate the unit/measurement of the numeric value through unit text. Using the unitTextPosition property, the text can be positioned either in front or back.

NOTE

By default, text appears at the back.

JAVASCRIPT

<script>
    var scale= [{
        //..
        labels: [{
            //for Major labels
            type: "major",
            unitText: "$",
            unitTextPosition: "front"
        },{
            //for Minor labels
            type: "minor",
            unitText: "$",
            unitTextPosition: "front"
        }]
    }];
    angular.module('PivotGaugeApp', ['ejangular']).controller('PivotGaugeCtrl', function ($scope) {
        //..
        $scope.scales = scale;
    });
</script>
