我在这里重新创建了ployly.js下拉图: 我在我的应用程序中复制并粘贴了代码,效果非常好 现在我只想复制这张图,把它放在原图下面。以下是html:Javascript 未捕获类型错误:无法读取属性';追加';空的,javascript,graph,plotly,Javascript,Graph,Plotly,我在这里重新创建了ployly.js下拉图: 我在我的应用程序中复制并粘贴了代码,效果非常好 现在我只想复制这张图,把它放在原图下面。以下是html: <div class="showcase__section" id="bubble"> <div class="spacer --small"></div> <div id="bubbleplots"> <div class="bubbleplot" data-num="0"

再说一遍
selector.appendChild(currentOption);
与第一个图形完美配合
因此currentOption1为空。为什么,我该如何修复它
这里有一个链接到
Plotly.d3.csv(https://raw.githubusercontent.com/plotly/datasets/master/gapminderDataFiveYear.csv,函数(错误,行){
函数解包(行、键){
返回行.map(函数(行){returnrow[key];});
}
var allCountryNames=unpack(行,'country'),
allYear=解包(行,“年”),
allGdp=unpack(行“gdpPercap”),
国家列表=[],
当前国家,
当前国内生产总值=[],
本年度=[];
对于(var i=0;i”+chosenCountry+“GDP”
};
Plotly.newPlot('plotdiv',数据,布局);
};
var innerContainer=document.querySelector(“[data num=“0”),
plotEl=innerContainer.querySelector('.plot'),
countrySelector=innerContainer.querySelector('.countrydata');
函数赋值选项(文本数组、选择器){
对于(var i=0;i”+chosenCountry+“GDP”
};
Plotly.newPlot('plotdiv1',数据,布局);
};
var innerContainer=document.querySelector(“[data num=“0”),
plotEl=innerContainer.querySelector('.plot1'),
countrySelector=innerContainer.querySelector('.countrydata1');
函数赋值选项(文本数组、选择器){
对于(var i=0;i
调用第一个下拉框,因此我将其更改为
var innerContainer = document.getElementById('bubble1')
在我在html中创建'bubble1'id以区分两者之后,它从第二组相同的数据中检索到了正确的数据
