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!
