Adding Custom Label Collection

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

<ej-pivotgauge [scales]="scales" >
</ej-pivotgauge>
//..

export class PivotGaugeComponent {
public scales;
    constructor() {
        //..
        this.scales = [{
                //...
                customLabels: [{
                position: {
                    x: 180,
                    y: 290
                }
            }]
        }];
    }
}

Appearance Customization

The appearance of the custom labels can be changed through the following properties.

  • position – used to set the position of the labels.
  • font – sets the font size, font style and font family of the label text.
  • color – sets the color of the label text.
  • textAngle – rotates the label to a specified angle. By default, the value is 0.

export class PivotGaugeComponent {
public scales;
    constructor() {
        //..
        this.scales = [{
                //...
                customLabels: [{
                position: {
                    x: 180,
                    y: 320
                },
                font: {
                    size: "12px",
                    fontFamily: "Segoe UI",
                    fontStyle: "Normal"
                },
                color: "blue",
                textAngle: 20
            }]
        }];
    }
}

    Multiple Custom Labels

    Multiple custom labels can be set to a PivotGauge widget by adding an array of objects within the customLabels option.

export class PivotGaugeComponent {
public scales;
    constructor() {
        //..
        this.scales = [{
                //...
                customLabels: [
                {
                    color: "Red",
                    font: {
                    size: "12px",
                    fontFamily: "Segoe UI",
                    fontStyle: "Normal"
                    },
                    position: {
                        x: 180,
                        y: 150
                    }
                }, 
                {
                    color: "Green",
                    font: {
                    size: "10px",
                    fontFamily: "Segoe UI",
                    fontStyle: "Normal"
                    },
                    position: {
                        x: 180,
                        y: 320
                    }
                }, 
                {
                    color: "Blue",
                    font: {
                    size: "10px",
                    fontFamily: "Segoe UI",
                    fontStyle: "Normal"
                    },
                    position: {
                        x: 180,
                        y: 290
                    }
                }
            ]
        }];
