Ranges

Adding Range Collection

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

HTML

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

TS

//..

export class PivotGaugeComponent {
public scales;
    constructor() {
        //..
        this.scales = [{
                //...
                showRanges: true,
                ranges: [{
                    distanceFromScale: 10
                }]
        }];
    }
}

Appearance Customization

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

• startValue – defines the start position of the range.
• endValue – defines the end position of the range.
• startWidth – sets the width at starting position of the range.
• endWidth – sets the width at ending position of the range.
• backgroundColor – sets the background color of the range.
• border – sets the height and width of the border of the range.
• placement – sets the position of the range.
• distanceFromScale – sets the distance between the range and scale.

Positioning the range could be set either through placement or distanceFromScale property.

NOTE

By default, placement takes the value “near”, whereas other enumeration values available are “far” and “center”.

TS

//..

export class PivotGaugeComponent {
public scales;
    constructor() {
        //..
        this.scales = [{
                //...
                showRanges: true,
                ranges: [{
                    startValue: 20,
                    endValue: 50,
                    startWidth: 2,
                    endWidth: 6,
                    backgroundColor: "yellow",
                    border: {
                        color: "red",
                        width: 2
                    },
                    distanceFromScale: 20
                }, 
                {
                    startValue: 50,
                    endValue: 100,
                    startWidth: 2,
                    endWidth: 7,
                    backgroundColor: "blue",
                    border: {
                        color: "green",
                        width: 2
                    },
                    placement: "near",
                }]
        }];
    }
}

NOTE

On setting both the position properties - “distanceFromScale” and “placement” for a range, the value set in “distanceFromScale” is given preference.

Multiple Ranges

Multiple ranges can be added by placing an array of objects in ranges option.

TS

//..

export class PivotGaugeComponent {
public scales;
    constructor() {
        //..
        this.scales = [{
                //...
                showRanges: true,
                ranges: [
                    {
                        startValue: 0,
                        endValue: 10,
                        backgroundColor: "Green",
                        distanceFromScale: -5
                    }, 
                    {
                        startValue: 10,
                        endValue: 30,
                        backgroundColor: "yellow",
                        distanceFromScale: -5
                    }, 
                    {
                        startValue: 30,
                        endValue: 50,
                        backgroundColor: "red",
                        distanceFromScale: -5
                    }
                ]
        }];
    }
}
