How to implement mobile-friendly statistical charts through PHP and Vue.js
With the popularity of mobile terminals, users' demand for data visualization is getting higher and higher. Statistical charts not only visually display data, but also help users better understand and analyze the data. In this article, we will introduce how to use PHP and Vue.js to implement mobile-friendly statistical charts.
// 数据库查询示例 $data = [ ['name' => 'A', 'value' => '100'], ['name' => 'B', 'value' => '200'], ['name' => 'C', 'value' => '150'], ];
First, introduce the ECharts library into the Vue component:
import echarts from 'echarts';
Then, define a component and initialize the chart in the mounted
hook function:
export default { mounted() { this.initChart(); }, methods: { initChart() { const chartDom = this.$refs.chart; const chart = echarts.init(chartDom); // 配置图表 const option = { xAxis: { type: 'category', data: this.data.map(item => item.name), }, yAxis: { type: 'value', }, series: [ { data: this.data.map(item => item.value), type: 'bar', }, ], }; // 渲染图表 chart.setOption(option); }, }, props: ['data'], };
In the above code, the chart is initialized through the mounted
hook function, and the ECharts API is used in the initChart
method to configure and render the chart.
data
property of the Vue component. <template> <div ref="chart" style="width: 100%; height: 300px;"></div> </template> <script> import echarts from 'echarts'; export default { mounted() { this.initChart(); }, methods: { initChart() { const chartDom = this.$refs.chart; const chart = echarts.init(chartDom); // 配置图表 const option = { xAxis: { type: 'category', data: this.data.map(item => item.name), }, yAxis: { type: 'value', }, series: [ { data: this.data.map(item => item.value), type: 'bar', }, ], }; // 渲染图表 chart.setOption(option); }, }, props: ['data'], }; </script>
In the above code, by introducing the container and components of ECharts in the <template></template>
tag, use it in the <script></script>
tag Get the data
to configure the chart.
<template> <div ref="chart" class="chart-container"></div> </template> <style> .chart-container { width: 100%; height: 300px; } @media (max-width: 768px) { .chart-container { height: 200px; } } @media (max-width: 480px) { .chart-container { height: 150px; } } </style>
In the above code, CSS media queries are used to set the height of the chart container for different device sizes.
Through the above steps, you can use PHP and Vue.js to implement mobile-friendly statistical charts. By using third-party libraries such as ECharts, various types of charts can be flexibly implemented to help users better display and analyze data.
