My goal is to create a system or website that can be fully resizable using CSS and the VW (viewport width) unit. Within this system, I have integrated a GoogleChart that functions with pixels. Now, I am looking for a way to scale the chart using Javascript/jQuery/CSS, specifically utilizing the transform scale property. This scaling should occur upon page load.
If anyone could provide guidance in achieving this, I would greatly appreciate it.
To better illustrate the issue, here is a JSFiddle link: https://jsfiddle.net/j9a9wpdj/
// Load the Visualization API and the corechart package.
google.charts.load('current', {'packages':['corechart']});
// Set a callback to run when the Google Visualization API is loaded.
google.charts.setOnLoadCallback(drawChart);
// Callback that creates and populates a data table,
// instantiates the pie chart, passes in the data and
// draws it.
function drawChart() {
// Create the data table.
var data = new google.visualization.DataTable();
data.addColumn('string', 'Topping');
data.addColumn('number', 'Slices');
data.addRows([
['Mushrooms', 3],
['Onions', 1],
['Olives', 1],
['Zucchini', 1],
['Pepperoni', 2]
]);
// Set chart options
var options = {'title':'How Much Pizza I Ate Last Night',
'width': 400,
'height': 300};
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
chart.draw(data, options);
}#test {
width: 80vw;
height: 40vw;
background-color: #dcdcdc;
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<div id="test">
<div id="chart_div"></div>
</div>[CONCLUSION] After experimenting, I found a solution that works well:
function zoomit() {
$("#chart-wrapper").css('zoom', $(window).width() / $("#chart-wrapper").width());
}
$(document).ready(zoomit);
$(window).resize(zoomit);
