Multilevel labels

The labelIntersectAction property is used to avoid overlapping of labels. The following code sample shows the setting of labelIntersectAction property to Hide.

var data = [];
var value = 0; var point = {};
for (var j = 1; j < 1090; j++) {
    value += (Math.random() * 10 - 5);
    value = value < 0 ? Math.abs(value) : value;
    point = { x: new Date(2000, 0, j), y: value, z: value + 10 };
    data.push(point);
}

var range = new ej.charts.RangeNavigator({
    labelPosition: 'Outside',
    tooltip: { enable: true },
    valueType: 'DateTime',
    intervalType: 'Quarter',
    enableGrouping: true,
    value: [new Date(2001, 0), new Date(2002, 0)],
    dataSource: data,
    xName: 'x',
    yName: 'y'
});
range.appendTo('#element');

Grouping

The second level axis labels can be grouped using “groupBy” property with the following interval types:

  • Auto
  • Years
  • Quarter
  • Months
  • Weeks
  • Days
  • Hours
  • Minutes
  • Seconds
var data = [];
var value = 0; let point = {};
for (var j = 1; j < 1090; j++) {
    value += (Math.random() * 10 - 5);
    value = value < 0 ? Math.abs(value) : value;
    point = { x: new Date(2000, 0, j), y: value, z: value + 10 };
    data.push(point);
}

var range = new ej.charts.RangeNavigator({
    labelPosition: 'Outside',
    tooltip: { enable: true },
    valueType: 'DateTime',
    intervalType: 'Quarter',
    enableGrouping: true,
    groupBy: 'Years',
    value: [new Date(2001, 0), new Date(2002, 0)],
    dataSource: data,
    xName: 'x',
    yName: 'y'
});
range.appendTo('#element');

Smart labels

The labelIntersectAction property is used to avoid overlapping of labels. The following code sample shows the setting of labelIntersectAction property to Hide.

var range = new ej.charts.RangeNavigator({
    valueType: 'DateTime',
    labelIntersectAction: 'Hide',
    labelFormat: 'y/M/d',
    value: [new Date("2017-08-13"), new Date("2017-12-28")],
    series: [{
        dataSource: datasrc, xName: 'x', yName: 'y', type: 'StepLine', width: 2,
    }],
});
range.appendTo('#element');

if(ele) {

Label positioning

By default, the labels can be placed outside the Range Selector. It can also be placed inside the Range Selector using the labelPosition property.

var range = new ej.charts.RangeNavigator({
    valueType: 'DateTime',
    labelPosition: 'Inside',
    value: [new Date("2017-08-13"), new Date("2017-12-28")],
    series: [{
        dataSource: datasrc, xName: 'x', yName: 'y', type: 'StepLine', width: 2,
    }],
});
range.appendTo('#element');

    </div>


<script>
var ele = document.getElementById('container');
if(ele) {
  ele.style.visibility = "visible";
}   
      </script>
<script src="index.js" type="text/javascript"></script>

Labels customization

The font size, color, family, etc. can be customized using the labelStyle setting.

var range = new ej.charts.RangeNavigator({
    valueType: 'DateTime',
    value: [new Date('2017-09-01'), new Date('2018-02-01')],
    labelFormat: 'MMM-yy',
    labelStyle: { color: 'red', size: '10px' },
    series: [{
        dataSource: datasrc, xName: 'x', yName: 'y', type: 'Area', width: 2,
    }],
});
range.appendTo('#element');
