结合chart.js插件，html代码：
<div><ul id="before-bg-color-list" class="simple-list color-list"><li class="before-fg-emerald padding10 margin10 place-left">收入</li><li class="before-fg-orange padding10 margin10 place-left">支出</li><li class="before-fg-red padding10 margin10 place-left">总和</li></ul></div><div style="width: 70%"><canvas id="canvas"></canvas></div><script>var randomScalingFactor = function(){ return Math.round(Math.random()*100)};var barChartData = {labels : ["一月","二月","三月","四月","五月","六月","七月","八月","九月","十月","十一月","十二月"],datasets : [{fillColor : "#008a00",strokeColor : "rgba(220,220,220,0.8)",highlightFill: "rgba(220,220,220,0.75)",highlightStroke: "rgba(220,220,220,1)",data : [<?php echo $countData?$countData[0]:"0,0,0,0,0,0,0,0,0,0,0,0"; ?>]},{fillColor : "#fa6800",strokeColor : "rgba(151,187,205,0.8)",highlightFill : "rgba(151,187,205,0.75)",highlightStroke : "rgba(151,187,205,1)",data : [<?php echo $countData?$countData[1]:"0,0,0,0,0,0,0,0,0,0,0,0"; ?>]},{fillColor : "#ce352c",strokeColor : "rgba(151,187,205,0.8)",highlightFill : "rgba(151,187,205,0.75)",highlightStroke : "rgba(151,187,205,1)",data : [<?php echo $countData?$countData[2]:"0,0,0,0,0,0,0,0,0,0,0,0"; ?>]}]}window.onload = function(){var ctx = document.getElementById("canvas").getContext("2d");window.myBar = new Chart(ctx).Bar(barChartData, {responsive : true});}</script></div>
效果如下：
