1、你可以用ppt画而且里面自带表格然后截图在把图片导入到html
2、html+js代码<!DOCTYPE html><html> <head> <title>Canvas测试</title> <meta charset="utf-8"> <script> //绘制饼图 function drawCircle(canvasId, data_arr, color_arr, text_arr) { var c = document.getElementById(canvasId); var ctx = c.getContext("2d"); var radius = c.height / 2 - 20; //半径 var ox = radius + 20, oy = radius + 20; //圆心 var width = 30, height = 10; //图例宽和高 var posX = ox * 2 + 20, posY = 30; // var textX = posX + width + 5, textY = posY + 10; var startAngle = 0; //起始弧度 var endAngle = 0; //结束弧度 for (var i = 0; i < data_arr.length; i++) { //绘制饼图 endAngle = endAngle + data_arr[i] * Math.PI * 2; //结束弧度 ctx.fillStyle = color_arr[i]; ctx.beginPath(); ctx.moveTo(ox, oy); //移动到到圆心 ctx.arc(ox, oy, radius, startAngle, endAngle, false); ctx.closePath(); ctx.fill(); startAngle = endAngle; //设置起始弧度 //绘制比例图及文字 ctx.fillStyle = color_arr[i]; ctx.fillRect(posX, posY + 20 * i, width, height); ctx.moveTo(posX, posY + 20 * i); ctx.font = 'bold 12px 微软雅黑'; //斜体 30像素 微软雅黑字体 ctx.fillStyle = color_arr[i]; //"#000000"; var percent = text_arr[i] + "：" + 100 * data_arr[i] + "%"; ctx.fillText(percent, textX, textY + 20 * i); } } function init() { //绘制饼图 //比例数据和颜色 var data_arr = [0.05, 0.25, 0.6, 0.1]; var color_arr = ["#00FF21", "#FFAA00", "#00AABB", "#FF4400"]; var text_arr = ["第一季度", "第二季度", "第三季度", "第四季度"]; drawCircle("canvas_circle", data_arr, color_arr, text_arr); } //页面加载时执行init()函数 window.onload = init; </script> </head> <body> <h3>HTML5绘制饼图演示</h3> <p> <canvas id="canvas_circle" width="500" height="300" style="border:2px solid #0026ff;" > 浏览器不支持canvas </canvas> </p> </body></html>
3、学习网站http://echarts.baidu.com/echarts2/doc/example.html
