將創建兩個餅圖，但第一個餅圖不會根據下拉列表顯示數據。它始終保持不變，并且數據不會更新。但是，第二個工作正常。這是我的代碼：//first pie chartfunction init() { var data = [{ values: [0, 0, 5, 9], labels: ["Bass", "Chilean", "Fish", "Seafood"], type: "pie" }]; var layout = { height: 600, width: 800 }; Plotly.plot("pie", data, layout);}function updatePlotly(newdata) { var PIE = document.getElementById("pie"); Plotly.restyle(PIE, "values", [newdata]);}function getData(dataset) { var data = []; switch (dataset) { case "dataset1": data = [0, 0, 5, 9]; break; case "dataset2": data = [0, 0, 5, 8]; break; case "dataset3": data = [0, 0, 2, 1]; break; default: data = [0, 0, 0, 0]; } updatePlotly(data);}init();//second pie chartfunction init2() { var data2 = [{ values: [1, 0, 42, 7], labels: ["Bass", "Chilean", "Fish", "Seafood"], type: "pie" }]; var layout2 = { height: 600, width: 800 }; Plotly.plot("pie2", data2, layout2);}function updatePlotly(newdata2) { var PIE2 = document.getElementById("pie2"); Plotly.restyle(PIE2, "values", [newdata2]);}function getData2(dataset2) { var data2 = []; switch (dataset2) { case "dataset4": data2 = [1, 0, 42, 7]; break; case "dataset5": data2 = [0, 0, 1, 4]; break; case "dataset6": data2 = [3, 7, 187, 37]; break; default: data2 = [0, 0, 0, 0]; } updatePlotly(data2);}兩者都顯示出來。我嘗試刪除第二個圖表，第一個圖表有效?？赡艹隽耸裁磫栴}？我為每個餅圖指定了不同的變量名稱。圖表不起作用的圖像：
嘗試在 2 個單獨的繪圖上創建 2 個餅圖.js它不會反映在指數上.html
