Google Chart

From simple line charts to complex hierarchical tree maps, the Google Chart gallery provides a large number of ready-to-use chart types:

  • Scatter Chart
  • Line Chart
  • Bar / Column Chart
  • Area Chart
  • Pie Chart
  • Donut Chart
  • Org Chart
  • Map / Geo Chart

How to Use Google Chart?

1. Add a <div> element (with a unique id) in the HTML where you want to display the chart:

<div id="myChart" style="max-width:700px; height:400px"></div>

2. Add a link to the charts loader:

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

3. Load the Graph API, and add the function to run when the API is loaded:

<script>
google.charts.load('current',{packages:['corechart']});
google.charts.setOnLoadCallback(drawChart);

// Your Function
function drawChart() {
...
}
</script>

Bar Charts

Source Code

function drawChart() {

// Set Data
const data = google.visualization.arrayToDataTable([
  ['Contry', 'Mhl'],
  ['Italy', 55],
  ['France', 49],
  ['Spain', 44],
  ['USA', 24],
  ['Argentina', 15]
]);

// Set Options
const options = {
  title: 'World Wide Wine Production'
};

// Draw
const chart = new google.visualization.BarChart(document.getElementById('myChart'));
chart.draw(data, options);

}
