This tutorial will show you every step you need to use amCharts 5 with Ember.js.

Installation

First, create a new Ember project:

npx -p ember-cli@latest ember new my-project --lang en
cd my-project

You can now run your project by using this command:

npm start

If you open up the URL http://localhost:4200/ you should see a working app.

Now it's time to add in an amCharts 5 chart. Use this command to install amCharts 5:

npm install --save-dev @ember/render-modifiers @amcharts/amcharts5

Create a new app/components/chart.hbs file:

<div
    {{did-insert this.create}}
    {{will-destroy this.cleanup}}
    style="width: 100%; height: 500px">
</div>

Also create a new app/components/chart.js file:

import Component from "@glimmer/component";
import { action } from "@ember/object";

import * as am5 from "@amcharts/amcharts5";
import * as am5xy from "@amcharts/amcharts5/xy";
import am5themes_Animated from "@amcharts/amcharts5/themes/Animated";

export default class ChartComponent extends Component {
    @action
    create(element) {
        const root = am5.Root.new(element);

        root.setThemes([
            am5themes_Animated.new(root)
        ]);

        root.dateFormatter.setAll({
            dateFields: ["valueX"]
        });

        const chart = root.container.children.push(am5xy.XYChart.new(root, {
            panX: false,
            panY: false,
            wheelX: "panX",
            wheelY: "zoomX"
        }));

        const cursor = chart.set("cursor", am5xy.XYCursor.new(root, {
            behavior: "zoomX"
        }));
        cursor.lineY.set("visible", false);

        const xAxis = chart.xAxes.push(am5xy.DateAxis.new(root, {
            maxDeviation: 0.5,
            baseInterval: {
                timeUnit: "day",
                count: 1
            },
            renderer: am5xy.AxisRendererX.new(root, {
                pan:"zoom"
            }),
            tooltip: am5.Tooltip.new(root, {})
        }));

        const yAxis = chart.yAxes.push(am5xy.ValueAxis.new(root, {
            maxDeviation:1,
            renderer: am5xy.AxisRendererY.new(root, {
                pan:"zoom"
            })
        }));

        const series = chart.series.push(am5xy.LineSeries.new(root, {
            name: "Series",
            xAxis: xAxis,
            yAxis: yAxis,
            valueYField: "value",
            valueXField: "date",
            tooltip: am5.Tooltip.new(root, {
                labelText: "{valueX}: {valueY}"
            })
        }));

        chart.set("scrollbarX", am5.Scrollbar.new(root, {
            orientation: "horizontal"
        }));

        const data = [
            {
                "date": 1686034800000,
                "value": 103
            },
            {
                "date": 1686121200000,
                "value": 99
            },
            {
                "date": 1686207600000,
                "value": 97
            },
            {
                "date": 1686294000000,
                "value": 101
            },
            {
                "date": 1686380400000,
                "value": 104
            },
            {
                "date": 1686466800000,
                "value": 106
            },
            {
                "date": 1686553200000,
                "value": 109
            },
            {
                "date": 1686639600000,
                "value": 114
            },
            {
                "date": 1686726000000,
                "value": 117
            },
            {
                "date": 1686812400000,
                "value": 113
            }
        ];
        series.data.setAll(data);

        series.appear(1000);
        chart.appear(1000, 100);

        this.series = series;
        this.root = root;
    }

    @action
    cleanup() {
        if (this.root) {
            this.root.dispose();
        }
    }
}

Lastly, change the app/templates/application.hbs file and add the <Chart /> component:

{{page-title "MyProject"}}

<Chart />

{{outlet}}

Now if you run npm start you should see a working chart.

Updating the chart

If you want to update the chart when an attribute changes, you can use the did-update modifier.

For this example, let's update the chart data whenever the data attribute changes.

First, let's change the chart code so that it uses the data from the attributes:

series.data.setAll(this.args.data);

Next, add in a new @action to the ChartComponent which will update the data:

@action
updateData() {
    if (this.series) {
        this.series.data.setAll(this.args.data);
    }
}

Lastly, add the did-update modifier into your app/components/chart.hbs file:

<div
    {{did-insert this.create}}
    {{will-destroy this.cleanup}}
    {{did-update this.updateData @data}}
    style="width: 100%; height: 500px">
</div>

Now you can pass in data to the <Chart /> component:

<Chart @data={{this.data}} />

If you want to update the chart when multiple different attributes change, you can use the did-update modifier multiple times:

<div
    {{did-insert this.create}}
    {{will-destroy this.cleanup}}
    {{did-update this.updateData @data}}
    {{did-update this.updateSize @size}}
    {{did-update this.updateZoom @zoom}}
    style="width: 100%; height: 500px">
</div>
