我有一個(gè)像這樣的 javascript 地圖..var Severity = {3M:[0, 3, 1, 0, 0],5T:[0, 0, 1, 0, 0],6S:[0, 0, 2, 0, 0]}以及調(diào)用 Stacked Chart Bar 的 JS 函數(shù)。在這里，我創(chuàng)建了一個(gè) JS 函數(shù)，它從 jsp 頁面獲取 id 和地圖。映射結(jié)構(gòu)與上面定義的相同。我想顯示圖表，其中 x 軸上的數(shù)據(jù)是地圖中的鍵，y 軸上是 5 個(gè)元素的堆疊數(shù)據(jù)。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' } ] }, } });}這里顯示圖表，我在 x 軸上得到標(biāo)簽......但圖表值不顯示，我得到以下錯(cuò)誤......HTML<canvas id="overall"></canvas><script>StackedBar('overall',Overall);</script> 我想知道出了什么問題，并希望我能幫助解決這個(gè)問題......
Charts Js Stacked Bar Graph 顯示沒有值？
