How to Use Google Chart?
To use Google Chart in your web page, add a link to the charts loader:
<script
src="https://www.gstatic.com/charts/loader.js">
</script>Google Chart is easy to use.
Just add a <div> element to display the chart:
<div id="myChart" style="max-width:700px; height:400px"></div>The <div> element must have a unique id.
Then load the Google Graph API
- Load the Visualization API and the corechart package
- Set a callback function to call when the API is loaded
1 google.charts.load('current',{packages:['corechart']});
2 google.charts.setOnLoadCallback(drawChart);That's all!
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:
Runnable example
const chart = new google.visualization.LineChart(document.getElementById('myChart'));Bar Charts
Source Code
function drawChart() {
const data = google.visualization.arrayToDataTable([ ['Contry', 'Mhl'], ['Italy', 55], ['France', 49], ['Spain', 44], ['USA', 24], ['Argentina', 15]
]);
const options = {
title: 'World Wide Wine Production'
};
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
Runnable example
const chart = new google.visualization.
PieChart
(document.getElementById('myChart'));3D Pie
To display the Pie in 3D, just add is3D: true to the options:
Runnable example
const options = {
title: 'World Wide Wine Production', is3D: true
};
