Data in EJ2 TypeScript Range navigator control

8 May 202324 minutes to read

Numeric

The numeric scale is used to represent the numeric values of data in a Range Selector. By default, the valueType of a Range Selector is Double.

import { RangeNavigator, StepLineSeries, DateTime } from "@syncfusion/ej2-charts";
RangeNavigator.Inject(StepLineSeries, DateTime);
import { double } from "./datasource.ts";

let range: RangeNavigator = new RangeNavigator({
    value: [12, 30],
    series: [{
        dataSource: double,
        xName: 'x', yName: 'y', type: 'StepLine', width: 2,
    }],
}, '#element');

Range

The minimum and the maximum of the scale will be calculated automatically based on the provided data. It can be customized by using the minimum, maximum, and interval properties.

import { RangeNavigator, StepLineSeries } from "@syncfusion/ej2-charts";
RangeNavigator.Inject(StepLineSeries);

let range: RangeNavigator = new RangeNavigator({
  minimum: 10, maximum: 160, interval: 10,
  value: [60, 100],
  series: [{
    dataSource: [
      { xData: 10, yData: 35 }, { xData: 20, yData: 28 },
      { xData: 30, yData: 34 }, { xData: 40, yData: 32 },
      { xData: 50, yData: 40 }, { xData: 60, yData: 30 },
      { xData: 70, yData: 4 }, { xData: 80, yData: 22 },
      { xData: 90, yData: 30 }, { xData: 100, yData: 43 },
      { xData: 110, yData: 60 }, { xData: 120, yData: 33 },
      { xData: 130, yData: 40 }, { xData: 140, yData: 29 },
      { xData: 150, yData: 10 }, { xData: 160, yData: 16 },
    ],
    xName: 'xData', yName: 'yData', type: 'StepLine', width: 2,
  }],
}, '#element');

Label Format

The numeric labels can be formatted using the labelFormat property and it supports all the globalized formats.

import { RangeNavigator, StepLineSeries, DateTime } from "@syncfusion/ej2-charts";
RangeNavigator.Inject(StepLineSeries, DateTime);
import { double } from "./datasource.ts";

let range: RangeNavigator = new RangeNavigator({
    labelFormat: 'n1',
    value: [12, 30],
    series: [{
        dataSource: double,
        xName: 'x', yName: 'y', type: 'StepLine', width: 2,
    }],
}, '#element');

The following table describes the result of applying some commonly used label formats on numeric values.

Label Value Label Format property value Result Description
1000 n1 1000.0 The Number is rounded to 1 decimal place
1000 n2 1000.00 The Number is rounded to 2 decimal place
1000 n3 1000.000 The Number is rounded to 3 decimal place
0.01 p1 1.0% The Number is converted to percentage with 1 decimal place
0.01 p2 1.00% The Number is converted to percentage with 2 decimal place
0.01 p3 1.000% The Number is converted to percentage with 3 decimal place
1000 c1 $1,000.0 The Currency symbol is appended to number and number is rounded to 1 decimal place
1000 c2 $1,000.00 The Currency symbol is appended to number and number is rounded to 2 decimal place

Custom Label Format

The Range Selector also supports the Custom Label formats using the placeholders such as {value}$, in which the value represents the axis label, e.g. 20$.

import { RangeNavigator, StepLineSeries, DateTime } from "@syncfusion/ej2-charts";
RangeNavigator.Inject(StepLineSeries, DateTime);
import { double } from "./datasource.ts";

let range: RangeNavigator = new RangeNavigator({
    // Custom label format
    labelFormat: '{value}$',
    value: [12, 30],
    series: [{
        dataSource: double,
        xName: 'x', yName: 'y', type: 'StepLine', width: 2,
    }],
}, '#element');

Logarithmic Axis

The Logarithmic supports the logarithmic scale, and it is used to visualize the data when the Range Selector has numerical values in both the lower (e.g.: 10-6) and the higher (e.g.: 106) orders of the magnitude.

import { RangeNavigator, StepLineSeries, Logarithmic } from "@syncfusion/ej2-charts";
RangeNavigator.Inject(StepLineSeries, Logarithmic);

let data: object[] = [];
let max: number = 100;
for (let i: number = 0; i < 100; i++) {
    data.push({
        x: Math.pow(10, i * 0.1),
        y: Math.floor(Math.random() * (80 - 30 + 1)) + 30
    });
}
let range: RangeNavigator = new RangeNavigator({
    valueType: 'Logarithmic',
    value: [4, 6],
    interval: 1,
    series: [{
        dataSource: data, xName: 'x', yName: 'y', type: 'StepLine', width: 2,
    }],
}, '#element');

To use logarithmic scale, inject the Logarithmic module using the RangeNavigator.Inject(Logarithmic)
method, and then set the valueType to Logarithmic.

Range

The minimum and the maximum of the Range Selector will be calculated automatically based on the provided data. It can be customized by using the minimum, maximum, and interval properties.

import { RangeNavigator, StepLineSeries, Logarithmic } from "@syncfusion/ej2-charts";
RangeNavigator.Inject(StepLineSeries, Logarithmic);

let data: object[] = [];
let max: number = 100;
for (let i: number = 0; i < 100; i++) {
    data.push({
        x: Math.pow(10, i * 0.1),
        y: Math.floor(Math.random() * (80 - 30 + 1)) + 30
    });
}
let range: RangeNavigator = new RangeNavigator({
    valueType: 'Logarithmic',
    value: [4, 6],
    interval: 1,
    series: [{
        dataSource: data, xName: 'x', yName: 'y', type: 'StepLine', width: 2,
    }],
}, '#element');

Logarithmic Base

The Logarithmic Base can be customized using the logBase property. The default value of this property is 10.

import { RangeNavigator, StepLineSeries, Logarithmic } from "@syncfusion/ej2-charts";
RangeNavigator.Inject(StepLineSeries, Logarithmic);

let data: object[] = [];
let max: number = 100;
for (let i: number = 0; i < 100; i++) {
    data.push({
        x: Math.pow(10, i * 0.1),
        y: Math.floor(Math.random() * (80 - 30 + 1)) + 30
    });
}
let range: RangeNavigator = new RangeNavigator({
    valueType: 'Logarithmic',
    value: [4, 6],
    // logBase for logarithmic scale
    logBase: 2,
    series: [{
        dataSource: data, xName: 'x', yName: 'y', type: 'StepLine', width: 2,
    }],
}, '#element');

Date-time

The Range Selector supports the DateTime scale and displays the DateTime values as labels in the specified format.

import { RangeNavigator, AreaSeries, DateTime } from "@syncfusion/ej2-charts";
RangeNavigator.Inject(AreaSeries, DateTime);
import { datasrc } from "./datasource.ts";

let range: RangeNavigator = new RangeNavigator({
    valueType: 'DateTime',
    value: [new Date("2017-08-13"), new Date("2017-12-28")],
    series: [{
        dataSource: datasrc, xName: 'x', yName: 'y', type: 'Area', width: 2,
    }],
}, '#element');

Date-time Range navigator supports date-time scale and displays date-time values as a labels in the specified format.

Interval Customization

The DateTime intervals can be customized using the interval and the intervalType properties of the Range Selector. For example, if the interval is set to 2 and the intervalType is set to years, the interval will be considered to be 2 years.

DateTime supports the following interval types:

  • Auto
  • Years
  • Quarter
  • Months
  • Weeks
  • Days
  • Hours
  • Minutes
import { RangeNavigator, AreaSeries, DateTime } from "@syncfusion/ej2-charts";
RangeNavigator.Inject(AreaSeries, DateTime);
import { datasrc } from "./datasource.ts";

let range: RangeNavigator = new RangeNavigator({
    valueType: 'DateTime',
    intervalType: 'Months',
    interval: 2,
    value: [new Date("2017-08-13"), new Date("2017-12-28")],
    series: [{
        dataSource: datasrc, xName: 'x', yName: 'y', type: 'Area', width: 2,
    }],
}, '#element');

Label Format

The labelFormat property is used to format and parse the date to all globalize format.

import { RangeNavigator, AreaSeries, DateTime } from "@syncfusion/ej2-charts";
RangeNavigator.Inject(AreaSeries, DateTime);
import { datasrc } from "./datasource.ts";

let range: RangeNavigator = new RangeNavigator({
    valueType: 'DateTime',
    labelFormat: 'y/M/d',
    value: [new Date("2017-08-13"), new Date("2017-12-28")],
    series: [{
        dataSource: datasrc, xName: 'x', yName: 'y', type: 'Area', width: 2,
