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

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
