[visualization-api] line chart with dates in php and mysql

[Joao castro pereira]

im developing a chart that show the price evolution over time.

When i was developing in my local server i could use a php while inside de 
script.. but after deployment for online server it no longer works.

the code i have now is:

<script type="text/javascript" 
src="https://www.gstatic.com/charts/loader.js";>
        
        
 



    <script type="text/javascript">
      google.charts.load('current', {'packages':['corechart']});
      google.charts.setOnLoadCallback(drawChart);

      function drawChart() {
          
          var data = new google.visualization.DataTable();
      data.addColumn('date', 'Team');
      data.addColumn('value', 'Season Start Date');
        data.addRows(
        
          
        
          
          <?php echo $dados;?>

        ]);

       

        var options = {

'backgroundColor': 'transparent',
'curveType': 'function',
'is3D':true
};

        var chart = new 
google.visualization.LineChart(document.getElementById('curve_chart'));

        chart.draw(data, options);
      }
    </script>

notice that the output from my $dados is:

[2018-09-06, 2.00],[2018-09-07, 2.00],[2018-09-07, 2.10],[2018-09-08, 
2.00],[2018-09-12, 2.95],[2018-09-12, 2.00],[2018-09-13, 2.10],[2018-09-13, 
2.10],[2018-10-04, 2.10],[2018-10-04, 2.10],[2018-10-04, 2.10],

but still no idea why it isn't working...

help please!!
