javascript - How can i iterate or get all object out of array with object key in Chart.js -


i working on making graph in chart.js, problem have , array objects 0: {y: 17854.69, y2: 14283.75, x: thu aug 17 2017 02:00:00 gmt+0200 (romance daylight time)} 1: {y: 41750.08, y2: 33400.06, x: wed aug 16 2017 02:00:00 gmt+0200 (romance daylight time)}

my graph have 2 y axes different data , x axes dates. chardata looks this. 

var chartdata = {                 labels: dates,                 datasets: [{                         yaxisid: "funding",                         label: "credorax dk funding",                         data: [{                                 y: credoraxdk[i].y,                                 x: credoraxdk[i].x                          }],                         position: "left",                     },                     {                         yaxisid: "release",                         label: "credorax dk release",                         data: [{                                 y: credoraxdk[i].y2,                                 x: credoraxdk[i].x                          }],                         position: "right",                     },

when try this, first object key out in array. there way can iterate through array given keys ?

my new chart looks this

                var ctx = document.getelementbyid("likviditetchart").getcontext("2d");             var chart = new chart(ctx, {                 type: "line",                 data: chartdata,                  options: {                     stacked: false,                     responsive: true,                     onhover: [],                     tooltips: {                         mode: "index",                         intersect: false                     },                     scales: {                         yaxes: [{                                 ticks: {                                     max: 100000,                                     min: 0,                                 },                                 type: "linear",                                 display: true,                                 title: "funding",                                 id: "funding",                                 position: "left",                              }, {                                 ticks: {                                     max: 100000,                                     min: 0,                                 },                                 type: "linear",                                 display: true,                                 title: "release",                                 id: "release",                                 position: "right",                             }]                     }                 }             });

picture of graph. can see there 2 points on graph, , have 6 objects in array, when write chart data this, chart.js puts out first object in array

hope problem can solved somehow.

if understood correctly, mean;

if have created chartdata, can acces dataset follows:

chartdata = {     datasets: [{               yaxisid: "funding",               label: "credorax dk funding",               data: [],               position: "left",         },         {               yaxisid: "release",               label: "credorax dk release",               data: [],               position: "right",         }    ,//other config, etc...   };  //init chart config var ctx = document.getelementbyid("likviditetchart").getcontext("2d"); var chart = new chart(ctx, chartdata);  //itterate data , add datasets (var = 0; < credoraxdk.length;i++){     chartdata.datasets[0].data.push({                             y: credoraxdk[i].y,                             x: credoraxdk[i].x});     chartdata.datasets[1].data.push({                             y: credoraxdk[i].y2,                             x: credoraxdk[i].x}); }  //update  new data. chart.update();

so basically, set chart config first, , add chart-data data array later.

don't forget call chart.update(); function when done.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
