canvas.js，在圖表中顯示一個值，但在X軸上顯示另一個值

Question

即時通訊使用CanvasJs顯示一些圖表。 當我將鼠標移到該點上時，它會顯示錯誤的日期。在圖片中Im超過12-jun，但它說11-jun ..在每個點上都發生相同的情況。

值“ 32”是確定的，日期不是確定的。

但是，如果我在單獨的圖表中顯示系列，則數據就可以了。

腳本：

$.getJSON("dataNro7.php", function (result) {


            var dps1 = [], dps2 = [];
        for(var i = 0; i < result.length; i++) {



            switch(result[i].palabra) {

            case 'pa': dps1.push({ x:  new Date (result[i].label), y: result[i].y });
                break;
            case 'ma': dps2.push({ x:  new Date(result[i].label), y: result[i].y });
                break;
            }
        }


                var revenueBarChart = new CanvasJS.Chart("Historiales2y3", {
                    animationEnabled: false,

Answer 1

如MDN中所述 ，

給定日期字符串為“ 2014年3月7日”，parse（）假定為本地時區，但給定ISO格式如“ 2014-03-07”，則它將假定為UTC時區（ES5和ECMAScript 2015）。 因此，根據系統支持的ECMAScript版本，使用這些字符串生成的Date對象可能表示不同的時刻，除非系統設置的本地時區為UTC。 這意味着看似等效的兩個日期字符串可能會導致兩個不同的值，具體取決於要轉換的字符串的格式。

請檢查此線程以獲取更多信息。

Answer 2

在推入DSP1和DSP2陣列之前，我將其添加進來：

var current = new Date(result[i].label); 
                var followingDay = new Date(current.getTime() + 12400000); 
                followingDay.toLocaleDateString();

我確定這不是超級准確。但是現在可以使用。
