谷歌LineChart mysql有更多行

Question

我正在尝试绘制谷歌折线图，但我在绘制第二行时遇到了一些问题。我正在使用mysql数据库中的数据，这些数据允许我显示2018年按月分组的销售总量。

但是我想显示每个责任组的总金额，这是我每一行中的一个字符串值。

这是我的代码：

<?php
 $curyear = date('Y');
 $con = mysqli_connect('xxxx','xxxx','xxxx','xxxx');
?>
<html>
  <head>
    <!--Load the AJAX API-->
    <script type="text/javascript" src="https://www.google.com/jsapi"></script>
    <script type="text/javascript">

      // Load the Visualization API and the piechart package.
      google.load('visualization', '1.0', {'packages':['corechart']});

      // Set a callback to run when the Google Visualization API is loaded.
      google.setOnLoadCallback(drawChart);

      // Callback that creates and populates a data table,
      // instantiates the pie chart, passes in the data and
      // draws it.
      function drawChart() {

        // Create the data table.
       var data = google.visualization.arrayToDataTable([
        ['Date', 'Pezzi',],
         <?php 
            $query = "SELECT responsabile, sum(n_sim)+sum(n_accessi) as pezzi, data_dichiarato FROM dichiarati WHERE responsabile = 'ADMRZ01' and n_ragsoc != 'DICHIARATO ZERO' and YEAR(DATA_DICHIARATO) = '$curyear' GROUP BY MONTH(data_dichiarato) ORDER BY data_dichiarato";
            $exec = mysqli_query($con,$query);
            while($row = mysqli_fetch_array($exec)){

            echo "['".date("M", strtotime($row['data_dichiarato']))."',".$row['pezzi']."],";

         }

        ?>

       ]);


        // Set chart options
        var options = {'title':'SIM CONSEGNATE NEL <?php echo $curyear; ?>',
                       'width':1200,
                       'height':300
                       // isStacked: true
                       };



        // Instantiate and draw our chart, passing in some options.
        var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
        chart.draw(data, options);



      }
    </script>
  </head>

  <body>
    <!--Divs that will hold the charts-->
    <div id="chart_div"></div>

  </body>
</html>

因此，您可以看到我有一个查询只提取责任ADMRZ01的数据。但在我的数据库中，我有ADMRZ02，ADMRZ11等行。

对于我正在添加的每项责任，我想在折线图中添加一行。

我该如何修改我的代码？是否有必要添加另一个查询？还是一个系列？对不起，我只是图表的初学者

谢谢
