Implements live highcharts in ionic 2

Question

I want to implement a live chart : http://www.highcharts.com/demo/dynamic-update/sand-signika in ionic 2, so angular2

I had tried many times, but always I got wrong.

I saw this code in js :

$(document).ready(function () {
    Highcharts.setOptions({
        global: {
            useUTC: false
        }
    });

    Highcharts.chart('container', {
        chart: {
            type: 'spline',
            animation: Highcharts.svg, // don't animate in old IE
            marginRight: 10,
            events: {
                load: function () {

                    // set up the updating of the chart each second
                    var series = this.series[0];
                    setInterval(function () {
                        var x = (new Date()).getTime(), // current time
                            y = Math.random();
                        series.addPoint([x, y], true, true);
                    }, 1000);
                }
            }
        },
        title: {
            text: 'Live random data'
        },
        xAxis: {
            type: 'datetime',
            tickPixelInterval: 150
        },
        yAxis: {
            title: {
                text: 'Value'
            },
            plotLines: [{
                value: 0,
                width: 1,
                color: '#808080'
            }]
        },
        tooltip: {
            formatter: function () {
                return '<b>' + this.series.name + '</b><br/>' +
                    Highcharts.dateFormat('%Y-%m-%d %H:%M:%S', this.x) + '<br/>' +
                    Highcharts.numberFormat(this.y, 2);
            }
        },
        legend: {
            enabled: false
        },
        exporting: {
            enabled: false
        },
        series: [{
            name: 'Random data',
            data: (function () {
                // generate an array of random data
                var data = [],
                    time = (new Date()).getTime(),
                    i;

                for (i = -19; i <= 0; i += 1) {
                    data.push({
                        x: time + i * 1000,
                        y: Math.random()
                    });
                }
                return data;
            }())
        }]
    });
});

But it gives me errors on Highcharts. Also on $(document(.ready()) but i just remove it and it works, so the problem is Highcharts.

Im woring in typescript so also the synthax is different. Also I saw this : here but no idea how to implement.

My purpose is to achive a realtime line chart in ionic 2.

If you want to use Highcharts in Angular2 you can do it via Angular2 HighCharts that provides the correct bindings.

The instructions worked fine for me:

From CL: npm install angular2-highcharts --save

In your App.module.ts:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ChartModule } from 'angular2-highcharts';
import { App } from './App';

@NgModule({
    imports: [
      BrowserModule, 
      ChartModule.forRoot(require('highcharts')
    ],
    declarations: [App],
    bootstrap: [App]
})
export class AppModule {}
