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);
}
Pie Charts
To convert a Bar Chart to a Pie chart, just replace:
google.visualization.BarChart
with:
google.visualization.PieChart
const chart = new google.visualization.PieChart(document.getElementById('myChart'));
3D Pie
To display the Pie in 3D, just add is3D: true to the options:
const options = {
title: 'World Wide Wine Production',
is3D: true
};
Line Graph
Source Code
function drawChart() {
// Set Data
const data = google.visualization.arrayToDataTable([
['Price', 'Size'],
[50,7],[60,8],[70,8],[80,9],[90,9],[100,9],
[110,10],[120,11],[130,14],[140,14],[150,15]
]);
// Set Options
const options = {
title: 'House Prices vs Size',
hAxis: {title: 'Square Meters'},
vAxis: {title: 'Price in Millions'},
legend: 'none'
};
// Draw Chart
const chart = new google.visualization.LineChart(document.getElementById('myChart'));
chart.draw(data, options);
}
Scatter Plots
To scatter plot the same data, change google.visualization to ScatterChart:
const chart = new google.visualization.ScatterChart(document.getElementById('myChart'));
