Javascript 图表Js堆叠条形图是否不显示值？
我有一个像这样的javascript映射Javascript 图表Js堆叠条形图是否不显示值？,javascript,html,chart.js,Javascript,Html,Chart.js,我有一个像这样的javascript映射 var Severity = { 3M:[0, 3, 1, 0, 0], 5T:[0, 0, 1, 0, 0], 6S:[0, 0, 2, 0, 0] } 和一个JS函数来调用堆叠图表栏。这里我创建了一个JS函数，它从jsp页面获取id和映射。映射结构与上面定义的相同。我想显示图形，其中x轴上的数据是地图中的关键点，y轴上的数据是5个元素的叠加数据 function StackedBar(id,Severity) { var label =
var Severity = {
3M:[0, 3, 1, 0, 0],
5T:[0, 0, 1, 0, 0],
6S:[0, 0, 2, 0, 0]
}
function StackedBar(id,Severity) {
var label = Object.keys(Severity); // getting the labels
var Critical = [];
var High = [];
var Medium = [];
var Low = [];
var Others = [];
for(let i=0;i<label.length;i++){ //assigning the data to arrays created
Critical.push(Severity[label[i]][0]);
High.push(Severity[label[i]][1]);
Medium.push(Severity[label[i]][2]);
Low.push(Severity[label[i]][3]);
Others.push(Severity[label[i]][4]);
}
var ctxL = document.getElementById(id).getContext('2d'); //id from the html canvas
var chart = new Chart(ctxL, {
type: 'bar',
data: {
labels: label,
datasets: [
{
label: 'Critical',
data: Critical,
backgroundColor: '#aa000e'
},
{
label: 'High',
data: High,
backgroundColor: '#e65905'
},
{
label: 'Medium',
data: Medium,
backgroundColor: '#e00ce6'
},
{
label: 'Low',
data: Low,
backgroundColor: '#b8ab16'
},
{
label: 'Others',
data: Others,
backgroundColor: '#00aaaa'
}
]
},
options: {
responsive: true,
legend: {
position: 'right'
},
scales: {
xAxes: [{
stacked: true
}],
yAxes: [{
stacked: true
}]
}
}
});
}
函数堆栈栏（id，严重性）{
var label=Object.keys（严重性）；//获取标签
风险值临界=[]；
var高=[]；
var中等=[]；
var低=[]；
var其他=[]；
例如（设i=0；i我将上述内容放在一个文件中，它可以正常工作（尽管我必须在调用中将“总体”更改为“严重性”）。因此，我预计您使用的内容可能与上面的示例不匹配

嘿，这是版本问题..我使用的是旧版本..更改为新版本..请不要发布代码、数据或错误消息的图像。请复制粘贴。请参考@toydarian…一定会这样做..谢谢
