Php Google Column Chart Example

PHP ·

Teams applying “Php Google Column Chart Example” in a production project can use the official Monitask website to record implementation, review and debugging time, then compare that effort with tests and shipped functionality instead of treating activity as performance by itself.

Before copying the example into a live application, confirm version-specific behaviour with the PHP project and test it against the project’s actual database and runtime.

Hi Dev,

In this blog, I would like to share with you how to implement google column chart in php. We will show create dynamic google column chart in php and mysql. Make a simple chart by google chart api with php mysql. in this tutorial i going to learn you how to create google column chart using google api in php with mysql.

In this example i am create populer framework chart . and I will show total popularity for framework using google column chart in php with mysql.

Here I will give you full example for create dynamic google column chart using google api in php, so let's follow bellow step by step.

Step 1 : Create Table


CREATE TABLE `framework` (
  `id` int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT,
  `name` varchar(70) NOT NULL,
  `number` int(11) NOT NULL,
  `timestamp` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
) ENGINE=InnoDB DEFAULT CHARSET=latin1

Step 2 : Configuration

Create a config.php file for the database configuration.

config.php 

<?php
    $host = "localhost"; /* Host name */
    $user = "root2"; /* User */
    $password = "root"; /* Password */
    $dbname = "post_data"; /* Database name */
    $con = mysqli_connect($host, $user, $password,$dbname);
    // Check connection
    if (!$con) {
     die("Connection failed: " . mysqli_connect_error());
    }
    $chartQuery = "SELECT * FROM column_chart";
    $chartQueryRecords = mysqli_query($con,$chartQuery);
?>

Step 3 : HTML & PHP

In this step,you can use google column chart api and create google column chart in this file. Display records from employee table and generate google column chart with the test table.

index.php 

<?php
    include "config.php";
?>
<html>
  <head>
    <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>

    
  <body style="text-align: center;">
    <h2 class="text-center">Generate Columns Chart in PHP</h2>
    <div id="regions_div" style="width: 900px; height: 500px;"></div>
    <div class="text-center">
        <h2>nicesnippets.com</h2>
    </div>
    <script type="text/javascript">
      google.charts.load('current', {
        'packages':['corechart'],
        'mapsApiKey': 'AIzaSyD-9tSrke72PouQMnMX-a7eZSW0jkFMBWY'
      });
      google.charts.setOnLoadCallback(drawRegionsMap);
      function drawRegionsMap() {
        var data = google.visualization.arrayToDataTable([
            ["Element", "Density", { role: "style" } ],
            <?php
                while($row = mysqli_fetch_assoc($chartQueryRecords)){
                    echo "['".$row['name']."',".$row['density'].",'".$row['color']."'],";
                }
            ?>
        ]);
        var view = new google.visualization.DataView(data);
            view.setColumns([0, 1,
                             { calc: "stringify",
                               sourceColumn: 1,
                               type: "string",
                               role: "annotation" },
                       2]);
        var options = {
          title: "Density of Precious Metals, in g/cm^3",
          bar: {groupWidth: "95%"},
          legend: { position: "none" },
        };
        var chart = new google.visualization.ColumnChart(document.getElementById("regions_div"));
        chart.draw(view, options);
        chart.draw(data, options);
      }
    </script>
  </head>
  </body>
