浏览器画图原理
canvas
- 基于像素
- 单个html,类似于画笔在画布上画画
- Echarts基于canvas画画
- 例子:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>canvas</title> </head> <body> <!-- 添加canvas标签,并加上红色边框以便于在页面上查看 --> <canvas id="myCanvas" width="400px" height="300px"> 您的浏览器不支持canvas标签。 </canvas> <script type="text/javascript"> //获取Canvas对象(画布) var canvas = document.getElementById("myCanvas"); var ctx = canvas.getContext("2d"); //开始一个新的绘制路径 ctx.beginPath(); //设置弧线的颜色为蓝色 ctx.strokeStyle = "blue"; var circle = { x: 100, //圆心的x轴坐标值 y: 100, //圆心的y轴坐标值 r: 50 //圆的半径 }; //沿着坐标点(100,100)为圆心、半径为50px的圆的顺时针方向绘制弧线 ctx.arc(circle.x, circle.y, circle.r, 0, Math.PI * 2, false); //按照指定的路径绘制弧线 ctx.stroke(); </script> </body> </html>
svg
- 基于对象模型
- 多个图形元素
- 高保真
- 例子:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"/> <title>svg</title> </head> <body> <svg width="100%" height="100%" version="1.1" xmlns="http://www.w3.org/2000/svg"> <!-- circle是圆形标签 --> <circle cx="70" cy="50" r="40" stroke="black" stroke-width="2" fill="red"/> <!-- rect是长方形标签 --> <rect x='120' width="100" height="100" style="fill:rgb(0,0,255);stroke-width:1; stroke:rgb(0,0,0)"/> </svg> </body> </html>
Echarts是基于canvas来画图的
常见的图形组件
- 标题、工具栏、图例、提示框
- 坐标轴
- X轴
- Y轴
柱状图
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>bar</title> <!-- 引入 echarts.js --> <script src="echarts.min.js"></script> </head> <body> <!-- 为ECharts准备一个具备大小(宽高)的Dom --> <div id="main" style="width: 900px;height:600px;"></div> <script type="text/javascript"> // 基于准备好的dom,初始化echarts实例 var myChart = echarts.init(document.getElementById('main')); // 指定图表的配置项和数据 var option = { // 标题 title: { text: 'ECharts 入门示例' }, // 工具箱 toolbox: { show: true, feature: { saveAsImage: { show: true } } }, // 图例 legend: { data: ['销量'] }, // x轴 xAxis: { data: ["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"] }, yAxis: {}, // 数据 series: [{ name: '销量', type: 'bar', data: [5, 20, 36, 10, 10, 20] }] }; // 使用刚指定的配置项和数据显示图表。 myChart.setOption(option); </script> </body> </html>
Echarts.init()
- 初始化Echarts实例
- setOption 用指定数据绘图
Option对象
- 标题:title
- 图例: legend
- X轴:xAxis
- Y轴: 没设默认使用了数据项里的数值
- 数据:series:
- Name,type和data
折线图
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>line</title> <!-- 引入 echarts.js --> <script src="echarts.min.js"></script> </head> <body> <!-- 为ECharts准备一个具备大小(宽高)的Dom --> <div id="main" style="width: 900px;height:600px;"></div> <script type="text/javascript"> // 基于准备好的dom,初始化echarts实例 var myChart = echarts.init(document.getElementById('main')); // 指定图表的配置项和数据 var option = { title: { text: 'ECharts 入门示例' }, toolbox: { show: true, feature: { saveAsImage: { show: true } } }, legend: { data: ['销量'] }, xAxis: { data: ["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"] }, yAxis: {}, series: [{ name: '销量', type: 'bar', data: [5, 20, 36, 10, 10, 20] }, { name: '产量', type: 'line', data: [7, 30, 50, 11, 40, 80] }] }; // 使用刚指定的配置项和数据显示图表。 myChart.setOption(option); </script> </body> </html>
