我正在读取文本文件并将文本文件中的数据放入数组中，并将数组作为Chart.js数据集字段中的数据传递，但不会绘制数据。我曾尝试使用更新功能，但我没有赢。当我将它们记录到控制台时，将填充数组。
这是我的JS和HTML：
/// <reference path="../scripts/angular.js" />
/// <reference path="angular-chart.min.js" />
/// <reference path="Chart.min.js" />
var app;
//Start of File Reader
var currentArray = new Array();
var voltageArray = new Array();
document.getElementById('inputFile').onchange = function () {
var file = this.files[0];
var reader = new FileReader();
reader.onload = function (progressEvent) {
var lines = this.result.split('\n');
for (var line = 4; line < lines.length - 2; line++) {
var pair = lines[line].split('\t');
if (!pair[0].includes(".") || !pair[1].includes(".")) {
voltageArray.push(parseFloat(pair[0].replace(' ', '.')));
currentArray.push(parseFloat(pair[1].replace(' ', '.')));
}
else {
voltageArray.push(parseFloat(pair[0]));
currentArray.push(parseFloat(pair[1]));
}
}
};
reader.readAsText(file);
};
//End of File Reader
console.log(voltageArray);
console.log(currentArray);
//Module
(function () {
app = angular.module("app", ['chart.js']);
})();
app.controller("lineCtrl_Voltage", function ($scope) {
let lineV = new Chart(document.getElementById("voltage"), {
