how to display three lines on chart

I create a chart using canvasjs. Values display in chart is from mysql database. All working but the problem is, it showing just 1 line on chart (sensors_pres) from table SensorData on chart not all three sensors_pres, sensors_temperature_data and sensors_humidity. Other problem is on range slider is not showing hour from 0 to 24, test it. Click in left-up on button all and in right-up you will see the number -1 to 96. How can i solve? I opened data.php file with browser and all values working correct.

Here is my html&javascript code

<!DOCTYPE HTML>    
<html>    
<head>
<script type="text/javascript" src="https://canvasjs.com/assets/script/jquery-1.11.1.min.js"></script>
<script type="text/javascript" src="https://canvasjs.com/assets/script/canvasjs.stock.min.js"></script>
<script type="text/javascript">
window.onload = function () {  
$.getJSON("data.php", function (result) {
  var stockChart = new CanvasJS.StockChart("chartContainer",{
    title:{
      text:"StockChart with Numeric Axis"
    },
    animationEnabled: true,
    exportEnabled: true,
    charts: [{
      axisX: {
        crosshair: {
          enabled: true,
          snapToDataPoint: true
        }
      },
      axisY: {
        crosshair: {
          enabled: true,
          //snapToDataPoint: true
        }
      },
      data: [{
        type: "line",
        dataPoints: result
    }]
    }],    
    rangeSelector: {
      inputFields: {
        startValue: 00,
        endValue: 24,
        valueFormatString: "###0"
      },
      
      buttons: [{
        label: "00",
        range: 00,
        rangeType: "number"
      },{
        label: "12",
        range: 12,
        rangeType: "number"
      },{
        label: "24",
        range: 24,
        rangeType: "number"
      },{
        label: "All",        
        rangeType: "all"
      }]
    }
  });

  stockChart.render();    
  })
}

</script>
</head>
<body>
<div id="chartContainer" style="height: 450px; width: 100%;"></div>
</body>
</html>

here is my php code:

<?php

header('Content-Type: application/json');

$con = mysqli_connect("fdb30.awardspace.net","3758712_lnd","bogdanutzu97","3758712_lnd");

// Check connection
if (mysqli_connect_errno($con))
{
    echo "Failed to connect to DataBase: " . mysqli_connect_error();
}else
{
    $data_points = array();

    $result = mysqli_query($con, "SELECT * FROM SensorData");

    while($row = mysqli_fetch_array($result))
    {        
        $point = array("label" => $row['reading_time'] , "y" => $row['sensors_pres'],$row['sensors_temperature_data'],$row['sensors_humidity']);

        array_push($data_points, $point);       
    }

    echo json_encode($data_points, JSON_NUMERIC_CHECK);
}
mysqli_close($con);

?>

Prop `className` did not match in next js app

I have written a sample code ( Github Link here ). this is a simple next js app, but giving me error when I refresh the page. This seems to be the common problem and I tried the fix provided in the internet but does not seem to fix my issue. The error is Warning: Prop className did not match. Server: "MuiBox-root MuiBox-root-1" Client: "MuiBox-root MuiBox-root-2". Did changes for _document.js, modified _app.js as mentioned in official website and solutions in stackoverflow. but nothing seems to work. Could someone take a look and help me whats wrong with the code? Via Active questions tagged javascript - Stack Overflow https://ift.tt/2FdjaAW
