Appearance and Styling

Angular RangeNavigator is enriched with lots of customization options for labels, gridlines and slider to develop high quality graphic rich control.

Customize labels

The labels are found along the range, displaying the value of the data it correspond, both on (higher level label) and below (lower level label) the RangeNavigator. RangeNavigator labels are further customized using “font” property in label Settings.

The higher level labels font Color, FontFamily, FontStyle, FontWeight, Opacity and Size can be customized using HigherLevel property.

The lower level labels font Color, FontFamily, FontStyle, FontWeight, Opacity and Size can be customized using LowerLevel property.

TS

this.labelSettings = {
    // customizing higher level labels.
    higherLevel: {
        style: {
            font: {
                color: '#ff0000',
                style: 'Normal',
                size: '12px',
                opacity: 1,
                weight: 'regular'
            },

        },
    },
    // customizing lower level labels.
    lowerLevel: {
        style: {
            font: {
                color: '#ff0000',
                style: 'Normal',
                size: '12px',
                opacity: 1,
                weight: 'regular'
            },
        },
    }
};

Label Placement

Labels in RangeNavigator are placed inside or outside of the control. You can customize both the higher and lower level labels using labelPlacement property in label setting of RangeNavigator. By default labelPlacement is “outside” for the both higher and lower level labels.

The following screen shot illustrates both the lower and higher level labels that are placed outside the control with labelPlacement specified as outside.

TS

// change Placement of higher and lower level label             
this.labelSettings = {
    higherLevel: {
        labelPlacement: "inside",
    },
    lowerLevel: {
        labelPlacement: "inside"
    }
};

HTML

<ej-rangenavigator [labelSettings]="labelSettings">
</ej-rangenavigator>

The following screenshot illustrates a RangeNavigator with labels inside the control after specifying the labelPlacement as inside.
