How to create your first chart using FusionCharts.js?
FusionCharts 是一个 JavaScript 库，当您想要创建图表和地图并将其放入您的 Web 中时可以使用它应用。在本教程中，我们将展示如何使用 FusionChart.js 创建两个不同的图表。
在学习如何创建图表之前，第一件重要的事情是了解如何将 FusionCharts 安装到本地计算机上。
安装FusionCharts
我们可以通过多种方式安装 FusionCharts。
使用 CDN
您可以使用下面给出的CDN链接直接访问FusionCharts的文件。
<script src="https://cdn.fusioncharts.com/fusioncharts/latest/fusioncharts.js"></script>
从 NPM 安装
您可以使用 NPM 将库作为依赖项安装到代码中。使用以下命令安装FusionCharts。
npm install --save fusioncharts
上述命令会将 FusionCharts 保存为项目中的 dev 依赖项。
既然我们知道了如何安装 FusionCharts，那么让我们来探讨一下我们将使用 FusionCharts 创建的几个图表示例。
示例 1
第一个示例是一个简单的条形图，我们将在 FusionCharts 的帮助下创建它，该图按国家/地区描述了亿万富翁的数量。考虑下面所示的代码。
index.html
<html>
<head>
<title>FusionChart Example - 1</title>
<script type="text/javascript"src="https://cdn.fusioncharts.com/fusioncharts/latest/fusioncharts.js"></script>
<script type="text/javascript"src="https://cdn.fusioncharts.com/fusioncharts/latest/themes/fusioncharts.theme.fusion.js"></script>
<script type="text/javascript">
const chartData = [{
"label": "United States","value": "735"
}, {
"label": "Mainland China","value": "539"
}, {
"label": "India", "value": "166"
}, {
"label": "Germany", "value": "134"
}, {
"label": "Russia", "value": "83"
}, {
"label": "Hong Kong", "value": "67"
}, {
"label": "Canada", "value": "64"
}, {
"label": "Brazil", "value": "62"
}, {
"label": "Italy", "value": "52"
}, {
"label": "Taiwan", "value": "51"
}];
const chartConfig = {
type: 'column2d',
renderAt: 'chart-container',
width: '100%',
height: '400',
dataFormat: 'json',
dataSource: {
// Configuration of Chart
"chart": {
"caption": "Billionares By Country Wise[2022]",
"subCaption": "According to Forbes",
"xAxisName": "Country",
"yAxisName": "Billionares",
"theme": "fusion",
},
// Actual Chart Data
"data": chartData
}
};
FusionCharts.ready(function() {
var fusioncharts = new FusionCharts(chartConfig);
fusioncharts.render();
});
</script>
</head>
<body>
<div id="chart-container">FusionCharts!!</div>
</body>
</html>
如果我们在浏览器中运行上述代码，我们将得到一个绘制为输出的条形图。
说明
在此代码中，我们首先创建了一个 JSON 数据，我们将在创建 FusionChart 对象的实例时将其传递到 chartConfig 的“data”属性中。
除此之外，“chartConfig”对象中还存在一些属性，尤其是“chart”属性，其中我们有不同的子属性，例如 caption、subCaption，这些属性在以下情况下都是必需的：我们正在绘制一个条形图。
示例 2
在上面的示例中，我们使用简单的 JSON 数据创建了一个条形图，并将其呈现给浏览器。在下面的示例中，我们将创建一个更复杂的图表，其中我们将描绘具有多个块的融合图表。考虑下面所示的代码。
index.html
<!DOCTYPE html>

<title>FusionChart - Example 2</title>

<script>
FusionCharts.ready(function() {
var conversionChart = new FusionCharts({

}],

}],
"trendlines": [{
"line": [{
"startValue": "20000",
"endValue": "30000",
"isTrendZone": "1",
"color": "#aaaaaa",
"alpha": "14"
},{
"startValue": "10000",
"endValue": "20000",
"isTrendZone": "1",
"color": "#aaaaaa",
"alpha": "7"
}
]
}],
"vTrendlines": [{
"line": [{
"startValue": "44",
"isTrendZone": "0",
"color": "#0066cc",
"thickness": "1",
"dashed": "1",
"displayValue": "Gross Avg."
}]
}]
}
});
conversionChart.render();
});
</script>
</body>
</html>
使用“编辑并运行”按钮运行此代码并查看输出。它将显示具有多个象限的图。
说明
在此示例中，我们尝试借助 FusionCharts 描绘多家移动设备公司的销售额。
这里，“数据集”属性包含我们将在图表中显示的实际 JSON 数据，而“类别”包含 X 轴和 Y 轴坐标的数据。
结论
在本教程中，我们使用了几个示例来演示如何利用 FusionCharts 库中的可用功能在 JavaScript 中创建不同的图表。

Demystifying JavaScript: What It Does and Why It Matters
Apr 09, 2025 am 12:07 AM
JavaScript is the cornerstone of modern web development, and its main functions include event-driven programming, dynamic content generation and asynchronous programming. 1) Event-driven programming allows web pages to change dynamically according to user operations. 2) Dynamic content generation allows page content to be adjusted according to conditions. 3) Asynchronous programming ensures that the user interface is not blocked. JavaScript is widely used in web interaction, single-page application and server-side development, greatly improving the flexibility of user experience and cross-platform development.
