Labels in EJ2 TypeScript Range navigator control
Multilevel labels
The labelIntersectAction
property is used to avoid overlapping of labels. The following code sample shows the setting of labelIntersectAction
property to Hide.
import { RangeNavigator, DateTime, RangeTooltip } from '@syncfusion/ej2-charts';
RangeNavigator.Inject(DateTime, RangeTooltip);
let data: object[] = [];
let value: number = 0; let point: object = {};
for (let j: number = 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);
}
let range: RangeNavigator = new 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'
}, '#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
import { RangeNavigator, DateTime, RangeTooltip } from '@syncfusion/ej2-charts';
RangeNavigator.Inject(DateTime, RangeTooltip);
let data: object[] = [];
let value: number = 0; let point: object = {};
for (let j: number = 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);
}
let range: RangeNavigator = new 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'
}, '#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.
import { RangeNavigator, StepLineSeries, DateTime } from "@syncfusion/ej2-charts";
RangeNavigator.Inject(StepLineSeries, DateTime);
import { datasrc } from "./datasource.ts";
let range: RangeNavigator = new 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,
}],
}, '#element');

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.
import { RangeNavigator, StepLineSeries, DateTime } from "@syncfusion/ej2-charts";
RangeNavigator.Inject(StepLineSeries, DateTime);
import { datasrc } from "./datasource.ts";
let range: RangeNavigator = new 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,
}],
}, '#element');

Labels customization
The font size, color, family, etc. can be customized using the labelStyle
setting.
import { RangeNavigator, DateTime } from '@syncfusion/ej2-charts';
import { GetDateTimeData } from './datasource.ts';
RangeNavigator.Inject(DateTime);
let range: RangeNavigator = new RangeNavigator(
{
valueType: 'DateTime',
intervalType: 'Months',
labelFormat: 'MMM',
labelStyle: { color: 'red', size: '10px' },
value: [new Date(2018, 5, 1), new Date(2018, 6, 1)],
dataSource: GetDateTimeData(new Date(2018, 0, 1), new Date(2019, 0, 1)),
xName: 'x', yName: 'y'
}, '#element');
