echarts 解决 X轴与Y轴数据不对应问题；X轴日期显示顺序错误问题

 

 

 

以上是最终成功效果。出现过的问题是： X轴日期显示顺序错误问题；X轴与Y轴数据不对应问题；

data 是 装满对象的数组。

注意： 叠加柱状图需要赋值 xData，而曲线可要可不要。

?

1	initChart3 是初始化叠加柱状图

?

1	initChart2 是初始化 曲线图

没有写明的函数：

根据数组 对象的时间字符串排序（转载）

https://www.cnblogs.com/hao-1234-1234/p/14269048.html

　　

经验教训：

这个问题是由数据缺失造成的，所以我开始就去数据库想要建一个新的视图，然后右连接补充一个有类别核心字段为空的行。

但我发现好几个类别的日期都不全，对数据库函数、产量并不擅长。所以我选择前端造成数据组装。但又有两个方法必须联动。

其实最简单的方法是服务器端 组装数据！

去重查询表所有日期

去重查询表所有类别。

for 类别[

for日期[

 根据类别和日期必须数据，有就赋值给对象a，没有就新建对象a. 然后把类别和日期赋值和它，核心字段为空。

]

]

这样前端代码不用改，比前端组装数据少改两个方法！

 

不要上来就做，而是思考多种技术方案，然后选择最容易的那种。

如果没有想到方案，要有最优解模式：

1、有极致的性能要求或能马上解决问题的sql方法，才考虑数据库端。（最后选）

 

2、有一定代码量或逻辑的，一定在服务器端解决。（首选）

3、传输的数据要最小化，带宽太大基本用不完，可以考虑前端组装数据。前端有简单实用的解决案例。前端方案比服务器端方案容易。（第二选）
