本文介绍了更新:基于x轴上的滑块日期更改图形的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我已经编辑了问题，现在的值已经解决了，以前的值不再反映在x轴上.现在，随着滑块的移动，数据在图中没有变化，我可以看到更改x值.
I have edited the question, earlier values were not reflecting on the x axis now that got resolved .Now as the slider moves the data doesn't change in the graph and i can see changing x values.
我正在尝试按照链接在d3中实现一个jquery滑块.该示例以以下格式生成一些随机数的数据:
I'm trying to implement a jquery slider in d3 following this link. The example is generating data of some random numbers while my data is in the below format:
{storeid: 5722646637445120, peoplesum: 87, date: "2018-06-03"}
{storeid: 5722646637445120, peoplesum: 90, date: "2018-06-04"}
{storeid: 5722646637445120, peoplesum: 114, date: "2018-06-05"}
我可以在移动滑块时触发事件，但是这些值现在未反映在图形上.因此，这意味着我的观点是无法正确更新SVG，这是我的假设.我在这里也可能是错的.
I'm able to trigger events when i move my slider but the values are not reflecting on the graph now. So that mean my view is not updating the SVG correctly which is my assumption. I could be wrong here as well.
我的x轴应该有日期范围，而y应该是peoplesum，它可以是单线图或多线图.
My x axis should have the date range and y should be peoplesum and it could be a single or a multiline graph.

推荐答案
添加剪切路径功能，因为数据超出了y轴.
Adding the clip path functionality because data was going beyond y axis.
