我们通常的做法就是用echarts来实现

比如

echarts象形柱图实现电量效果柱状图

接着我们实现进阶版，增加渐变效果

echarts分割柱形图实现渐变电量效果柱状图

接着是又在渐变的基础上，增加了背景色块的填充

echarts实现渐变电量效果柱状图

其实思路是一致的，就是效果层的叠加

以上，就是在项目中实际会用到的效果

如果你只是想做一个静态demo，不需要数据，不需要后台，这里教你一个简单快捷的方法，用css实现！

实现效果如下↓

相关代码：

<template><!--css实现电量效果--><div class="panel"><div class="content"><div class="legend"><div class="legend-item"><span class="legend-icon" style="background:linear-gradient(0deg,rgba(247,240,42,1),rgba(255,84,84,1));"></span><span class="legend-label">报修</span></div><div class="legend-item"><span class="legend-icon" style="background:linear-gradient(0deg,rgba(22,233,16,1),rgba(22,230,247,1));"></span><span class="legend-label">维护</span></div></div><div class="chart"><div class="chart-item" v-for="(item,index) in datas"><div class="chart-bg"><span class="char-bg-item" v-for="n in 12" v-bind:style="char_bg_item_style1(item,n)"></span></div><div class="chart-bg"><span class="char-bg-item" v-for="n in 12" v-bind:style="char_bg_item_style2(item,n)"></span></div><div class="chart-label">{{item.label}}</div></div></div></div></div>
</template>

};
</script>
