二. 本文主要对面积对比图，扇形图，柱状图三大常见图进行介绍
效果图如下：
html代码：

我们在html页面内加入三个画布标签canvas，插入面积对比图，扇形图，柱状图；
css代码：
.instrument-panel{ display: flex; flex-direction: column; align-items: center; } .instrument-panel .panel-con{ width: 90%; height: 720px; display: flex; flex-direction: column; align-items: center; margin: 65px 0px; } .instrument-panel .panel-con .panel-linear{ width: 100%; height: 340px; background-color: #fff; margin-bottom: 40px; display: flex; align-items: center; justify-content: center; position: relative; } .panel-linear .consumption{ position: absolute; left: 24px; top: 44px; color: #333; font-size: 18px; } .panel-linear canvas{ width: 80%; height: 300px; } .instrument-panel .panel-con .panel-other{ width: 100%; height: 340px; display: flex; flex-direction: row; align-items: center; justify-content: space-between; } .panel-con .panel-other .panel-pancake{ width: 48.5%; height: 340px; background-color: #fff; display: flex; align-items: center; justify-content: center; position: relative; } .panel-pancake canvas{ width: 70%; height: 340px; } .panel-pancake .product-proportion{ position: absolute; left: 24px; top: 44px; color: #333; font-size: 18px; } .panel-con .panel-other .panel-columnar{ width: 48.5%; height: 340px; background-color: #fff; display: flex; align-items: center; justify-content: center; position: relative; } .panel-columnar canvas{ width: 70%; height: 220px; margin-top: 40px; } .panel-columnar .user-map{ position: absolute; left: 24px; top: 44px; color: #333; font-size: 18px; }
重点来了，我们使用ajax接口数据实时监测数据的变化，并呈现在图表上面
三. 接口数据形式
1.面积对比图：
{"state": 200, "result": [{"goodsId": 1, "sum": 0, "creatTime": "2018-08-31"}, {"goodsId": 2, "sum": 0, "creatTime": "2018-08-31"}, {"goodsId": 1, "sum": 0, "creatTime": "2018-09-01"}, {"goodsId": 2, "sum": 1, "creatTime": "2018-09-01"}, {"goodsId": 1, "sum": 0, "creatTime": "2018-09-02"}, {"goodsId": 2, "sum": 0, "creatTime": "2018-09-02"}, {"goodsId": 1, "sum": 0, "creatTime": "2018-09-03"}, {"goodsId": 2, "sum": 0, "creatTime": "2018-09-03"}, {"goodsId": 1, "sum": 0, "creatTime": "2018-09-04"}, {"goodsId": 2, "sum": 0, "creatTime": "2018-09-04"}, {"goodsId": 1, "sum": 0, "creatTime": "2018-09-05"}, {"goodsId": 2, "sum": 1, "creatTime": "2018-09-05"}, {"goodsId": 1, "sum": 0, "creatTime": "2018-09-06"}, {"goodsId": 2, "sum": 0, "creatTime": "2018-09-06"}, {"goodsId": 1, "sum": 0, "creatTime": "2018-09-07"}, {"goodsId": 2, "sum": 0, "creatTime": "2018-09-07"}, {"goodsId": 1, "sum": 0, "creatTime": "2018-09-08"}, {"goodsId": 2, "sum": 0, "creatTime": "2018-09-08"}, {"goodsId": 1, "sum": 0, "creatTime": "2018-09-09"}, {"goodsId": 2, "sum": 0, "creatTime": "2018-09-09"}, {"goodsId": 1, "sum": 0, "creatTime": "2018-09-10"}, {"goodsId": 2, "sum": 0, "creatTime": "2018-09-10"}, {"goodsId": 1, "sum": 0, "creatTime": "2018-09-11"}, {"goodsId": 2, "sum": 0, "creatTime": "2018-09-11"}, {"goodsId": 1, "sum": 0, "creatTime": "2018-09-12"}, {"goodsId": 2, "sum": 0, "creatTime": "2018-09-12"}, {"goodsId": 1, "sum": 0, "creatTime": "2018-09-13"}, {"goodsId": 2, "sum": 0, "creatTime": "2018-09-13"}, {"goodsId": 1, "sum": 4, "creatTime": "2018-09-14"}, {"goodsId": 2, "sum": 0, "creatTime": "2018-09-14"}, {"goodsId": 1, "sum": 0, "creatTime": "2018-09-15"}, {"goodsId": 2, "sum": 0, "creatTime": "2018-09-15"}]}
2.扇形图：
{"state": 200, "result": [{"goodsId": 2, "sum": 4}, {"goodsId": 1, "sum": 2}]}
3.柱状图：
{"state": 200, "result": {"sum_lastmonth": 6, "marked": 4, "unmarked": 2}}
js代码：
