无法显示堆叠列动态 json 数据

Question

大家好，我正在寻找有关在 php 中创建带有动态数据的测试图表的帮助。

首先我创建了没有问题的图表。

window.onload = function () {

     chart = new CanvasJS.Chart("chartContainer", {
       animationEnabled: true,
   title:{
     text: "Gasto Proyectado (neto)"
   },
   axisX: {
     interval: 1,
     intervalType: "month",
     valueFormatString: "MM/YYYY"
   },
   axisY: {
     suffix: "",
     valueFormatString: "$#,###"
   },
   toolTip: {
     shared: true
   },
   legend: {
     reversed: true,
     verticalAlign: "center",
     horizontalAlign: "right",
     cursor: "pointer",
     itemclick: toggleDataSeries
   },
       data:[

<?php

$gastoMensualProyectado = Helper::gastoMensualProyectado();
//var_dump($gastoMensualProyectado);
//die();

 $controlCostoN1= array();
 foreach ($gastoMensualProyectado as $key => $value) {
       $controlCostoN1[]= $value['name'];
 }

 $controlCostoN1 = array_unique($controlCostoN1);


$output = '';
foreach ($controlCostoN1 as $indice => $name) {


     $output .= '{
       type: "stackedColumn",
       name: "'.$name.'",
       showInLegend: true,
       xValueFormatString: "MMM, YYYY",
       yValueFormatString: "$#,###",
       dataPoints:[';

       foreach ($gastoMensualProyectado as $key => $value) {
         if ($name == $value['name']){
           $output.='{ x:'.$value['x'].', y:'.$value['y'].'},';
         }
       }
$output .=']},';
}

$output = substr($output,0,-3);

print $output;

?>
]
}]

     });
     chart.render();

然后我想放置新数据调用 php 文件，该文件响应 json_encode 函数


 $dps = array();
     $i=0;
     $header = '';


     foreach ($controlCostoN1 as $indice => $name) {
       //$val[$i] = 'type: "stackedColumn",name: "'.$name.'",showInLegend: true,xValueFormatString: "MMM, YYYY",yValueFormatString: "$#,###",dataPoints:';
       //var_dump($name);
       foreach ($gastoMensualProyectado as $key => $value) {
       // echo $name;
          if ($name == $value['name']){
             $dps[][$name] = $value;
             /*
             $header .= '{
               type: "stackedColumn",
               name: "'.$name.'",
               showInLegend: true,
               yValueFormatString: "#,##0 MW",
               dataPoints: ';
               //$points[] = '{ x:'.$value['x'].', y:'.$value['y'].'},';
               //$dps[] = [ "x" => $value['x'], "y" => $value['y'] ];
               .json_encode($value, JSON_NUMERIC_CHECK).'
             },';
             */
           }
         }
       }

      // $output = substr($output,0,-3);
      echo json_encode($dps);`

然后尝试在更改 a select 时刷新图表中的数据，但 grph 根本没有任何列。



` $('#idPresupuesto').change(function(event) {
       var dps = [];
       var names = [];
       var response;
       $.getJSON("acciones/obtenerDatosStackedColumns.json.php", { idPresupuesto: $(this).val() } ,function(data) {

          // console.log(data);
         // console.log("swasaddsaasd");
          $.each(data, function(key, value){
            // dataPoints.push({x: value[0], y: parseInt(value[1])});
            // console.log(value.first());
            // console.log(value[Object.keys(value)[0]].name);
            // value.map()
            jQuery.map( value , function( n, i){


              if(jQuery.inArray(n.name,names) < 0){
                names.push(n.name);
                //console.log(n.name);
              }




            });
         });


         $.each(data, function(key, value){
           // console.log(key);
           jQuery.map( value , function( n, i){
             // console.log(n.x + "  "+n.y);
             dps.push({x: n.x, y: parseInt(n.y)});
             // console.log();
           });
         });

          console.log(dps);
          // console.log(names);
          // console.log(names.length);

          var chart = new CanvasJS.Chart("chartContainer",{
            title:{
              text:"Presupuesto"
            },
            animationEnabled: true,
            data: [{
              dataPoints : dps,
            }]
          });

          chart.render();
       });
     });`

json 响应是：

        "name": "Mano de Obra"
    }
}]

实际上第一个图表呈现良好，但当我尝试更新数据时显示一个空图表。

Answer 1

我修改了 json 日期

的内容

"x": "new Date(2019, 3)",

至

"x": "2019, 3",

然后将对象 Date

应用于此行

$output.='{ x:new Date('.$value['x'].'), y:'.$value['y'].'},';

图表动态效果很好！

希望这对某人有所帮助。
