Getting Started

Requirements

• Node.js, NPM/Yarn installed globally in your OS.
• FusionCharts and Svelte installed in your project, as detailed below:

Installation

There are multiple ways to install svelte-fusioncharts component.

Install from NPM

npm install --save svelte-fusioncharts

See npm documentation to know more about npm usage.

Usage

Import svelte-fusioncharts and FusionCharts in your app:

<script>
  import FusionCharts from 'fusioncharts/core';
  import Column2d from 'fusioncharts/viz/column2d';
  import SvelteFC, { fcRoot } from 'svelte-fusioncharts';

  fcRoot(FusionCharts, Column2d);
</script>

Note: This way of import will not work in IE11 and below.

Quick Start

Here is a basic sample that shows how to create a chart using svelte-fusioncharts:

<script>
  import FusionCharts from 'fusioncharts';
  import Charts from 'fusioncharts/fusioncharts.charts';
  import FusionTheme from 'fusioncharts/themes/fusioncharts.theme.fusion';
  import SvelteFC, { fcRoot } from 'svelte-fusioncharts';

  // Always set FusionCharts as the first parameter
  fcRoot(FusionCharts, Charts, FusionTheme);

  const dataSource = {
    chart: {
      caption: 'Countries With Most Oil Reserves [2017-18]',
      subCaption: 'In MMbbl = One Million barrels',
      xAxisName: 'Country',
      yAxisName: 'Reserves (MMbbl)',
      numberSuffix: 'K',
      theme: 'fusion'
    },
    data: [
      { label: 'Venezuela', value: '290' },
      { label: 'Saudi', value: '260' },
      { label: 'Canada', value: '180' },
      { label: 'Iran', value: '140' },
      { label: 'Russia', value: '115' },
      { label: 'UAE', value: '100' },
      { label: 'US', value: '30' },
      { label: 'China', value: '30' }
    ]
  };

  const chartConfigs = {
    type: 'column2d',
    width: 600,
    height: 400,
    dataFormat: 'json',
    dataSource: dataSource
  };
</script>

<SvelteFC {...chartConfigs} />

Render FusionMaps

To render a map, import the FusionMaps module along with the map definition.

<script>
  import FusionCharts from 'fusioncharts';
  import Maps from 'fusioncharts/fusioncharts.maps';
  import World from 'fusioncharts/maps/fusioncharts.world';
  import FusionTheme from 'fusioncharts/themes/fusioncharts.theme.fusion';
  import SvelteFC, { fcRoot } from 'svelte-fusioncharts';

  // Always set FusionCharts as the first parameter
  fcRoot(FusionCharts, Maps, World, FusionTheme);

  const dataSource = {
    chart: {
      caption: 'Average Annual Population Growth',
      subcaption: ' 1955-2015',
      numbersuffix: '%',
      includevalueinlabels: '1',
      labelsepchar: ': ',
      entityFillHoverColor: '#FFF9C4',
      theme: 'fusion'
    },
    colorrange: {
      minvalue: '0',
      code: '#FFE0B2',
      gradient: '1',
      color: [
        { minvalue: '0.5', maxvalue: '1.0', color: '#FFD74D' },
        { minvalue: '1.0', maxvalue: '2.0', color: '#FB8C00' },
        { minvalue: '2.0', maxvalue: '3.0', color: '#E65100' }
      ]
    },
    data: [
      { id: 'NA', value: '.82', showLabel: '1' },
      { id: 'SA', value: '2.04', showLabel: '1' },
      { id: 'AS', value: '1.78', showLabel: '1' },
      { id: 'EU', value: '.40', showLabel: '1' },
      { id: 'AF', value: '2.58', showLabel: '1' },
      { id: 'AU', value: '1.30', showLabel: '1' }
    ]
  };

  const chartConfigs = {
    type: 'world',
    width: 600,
    height: 400,
    dataFormat: 'json',
    dataSource: dataSource
  };
</script>

<SvelteFC {...chartConfigs} />

Working with Events

To attach event callbacks to a FusionCharts component, follow the sample below.

<script>
  import FusionCharts from 'fusioncharts';
  import Charts from 'fusioncharts/fusioncharts.charts';
  import FusionTheme from 'fusioncharts/themes/fusioncharts.theme.fusion';
  import SvelteFC, { fcRoot } from 'svelte-fusioncharts';

  // Always set FusionCharts as the first parameter
  fcRoot(FusionCharts, Charts, FusionTheme);

  const dataSource = {
      chart: {
        caption: 'Countries With Most Oil Reserves [2017-18]',
        subCaption: 'In MMbbl = One Million barrels',
        xAxisName: 'Country',
        yAxisName: 'Reserves (MMbbl)',
        numberSuffix: 'K',
        theme: 'fusion'
      },
      data: [
        { label: 'Venezuela', value: '290' },
        { label: 'Saudi', value: '260' },
        { label: 'Canada', value: '180' },
        { label: 'Iran', value: '140' },
        { label: 'Russia', value: '115' },
        { label: 'UAE', value: '100' },
        { label: 'US', value: '30' },
        { label: 'China', value: '30' }
      ]
    },
    dataplotClickHandler = event => {
      // code for dataplotClick event handler
    },
    renderCompleteHandler = event => {
      // code for renderComplete event handler
    };

  const chartConfigs = {
    type: 'column2d',
    width: 600,
    height: 400,
    dataFormat: 'json',
    dataSource: dataSource
  };
</script>

<SvelteFC
  {...chartConfigs}
  on:dataplotClick={dataplotClickHandler}
  on:renderComplete={renderCompleteHandler}
/>

Working with APIs

To call APIs we will need the chart object. To get the chart object for an SvelteFC component, bind a variable with the chart property of SvelteFC component.

<script>
  import FusionCharts from 'fusioncharts';
  import Charts from 'fusioncharts/fusioncharts.charts';

  import FusionTheme from 'fusioncharts/themes/fusioncharts.theme.fusion';
  import SvelteFC, { fcRoot } from 'svelte-fusioncharts';

  fcRoot(FusionCharts, Charts, FusionTheme);

  let chartObj,
    dataSource = {
      "chart": {
        "caption": "Market Share of Web Servers",
        "plottooltext": "<b>$percentValue</b> of web servers run on $label servers",
        "showLegend": "1",
        "showPercentValues": "1",
        "legendPosition": "bottom",
        "useDataPlotColorForLabels": "1",
        "enablemultislicing": "0",
        "showlegend": "0",
        "theme": "fusion",
      },
      "data": [{
        "label": "Apache",
        "value": "32647479"
      }, {
        "label": "Microsoft",
        "value": "22100932"
      }, {
        "label": "Zeus",
        "value": "14376"
      }, {
        "label": "Other",
        "value": "18674221"
      }]
    },
    chartConfig = {
      type: 'pie2d',
      width: '600',
      height: '400',
      renderAt: 'chart-container',
      dataSource
    };

  const sliceDataPlot = (index, sliceOut = true) => {
    chartObj.slicePlotItem(index, sliceOut)
  };
</script>

<div id="chart-container" >
  <SvelteFC {...chartConfig} bind:chart={chartObj} />
</div>

<button on:click={() => {
  sliceDataPlot(1);
}}>
  Slice out
</button>
<button on:click={() => {
  sliceDataPlot(1, false);
}} >
  Slice in
</button>

Usage and integration of FusionTime

From fusioncharts@3.13.3-sr.1, You can visualize timeseries data.

Learn more about FusionTime here.

Consider the example below for integration of FusionTime

<script>
  import FusionCharts from 'fusioncharts';
  import Timeseries from 'fusioncharts/fusioncharts.timeseries';
  import SvelteFC, { fcRoot } from 'svelte-fusioncharts';

  fcRoot(FusionCharts, Timeseries);

  let promise,
    jsonify = res => res.json(),
    dataFetch = fetch(
      'https://s3.eu-central-1.amazonaws.com/fusion.store/ft/data/line-chart-with-time-axis-data.json'
    ).then(jsonify),
    schemaFetch = fetch(
      'https://s3.eu-central-1.amazonaws.com/fusion.store/ft/schema/line-chart-with-time-axis-schema.json'
    ).then(jsonify);

  promise = Promise.all([dataFetch, schemaFetch]);

  const getChartConfig = ([data, schema]) => {
    const fusionDataStore = new FusionCharts.DataStore(),
      fusionTable = fusionDataStore.createDataTable(data, schema);

    return {
      type: 'timeseries',
      width: '100%',
      height: 450,
      renderAt: 'chart-container',
      dataSource: {
        data: fusionTable,
        caption: {
          text: 'Sales Analysis'
        },
        subcaption: {
          text: 'Grocery'
        },
        yAxis: [
          {
            plot: {
              value: 'Grocery Sales Value',
              type: 'line'
            },
            format: {
              prefix: '$'
            },
            title: 'Sale Value'
          }
        ]
      }
    };
  };
</script>

<div id="chart-container" >
  {#await promise}
    <p>Fetching data and schema...</p>
  {:then value}
    <SvelteFC
      {...getChartConfig(value)}
    />
  {:catch error}
    <p>Something went wrong: {error.message}</p>
  {/await}
</div>
