问题描述

我正试图添加一个下拉框菜单，我将在其中进行选择以可视化数据.没有下拉框，我的可视化效果很好，但是当我将它们放在一起时，出现了问题.在我的代码中，当我选择selection02时，我想可视化数据.有人可以帮我吗?

I'm trying to to add a drop-down box menu in which i will make my choice in order to visualize data. My visualization works fine without the drop-down box but when i put them together something goes wrong. In my code i want to visualize the data when i choose selection02. Could anyone help me?
