按周记录计数

：

[{"day": "2017-09-28T00:00:00Z", "count_items": 2}, {"day": "2017-09-30T00:00:00Z", "count_items": 2}]

我的目标是实现类似于小提琴的东西：在填充下一个图形之前，一个图形中隐藏了什么，有人能帮我找出代码的错误吗？还有没有其他更好的方法来调整此代码以提高性能，而不是在

if

和

else if

循环中编写几乎相同的代码，由于两个图形几乎相同，但数据和x轴不同。

问题在于每次更改选择时都要添加新的SVG

var svg=d3.select（“body”）.append（“svg”）

这个错误有点愚蠢，没有将svg追加到

body

，而是应该将它追加到id

#图表
var svg=d3.select（“chart”）.append（“svg”）

这最终解决了问题。
