Example: Basic Charts Implementation

Creating a simple Chart instance

The Charts module allows you to create and customize different chart types. All you need to get started is a data provider (array), one line of code and a dom element (div) in which to render the Chart.

CSS

#mychart {
    margin:10px 10px 10px 10px;
    width:90%;
    max-width: 800px;
    height:400px;
}

HTML

<div id="mychart"></div>

JavaScript

YUI().use('charts', function (Y) 
{ 
    var myDataValues = [ 
        {category:"5/1/2010", values:2000}, 
        {category:"5/2/2010", values:50}, 
        {category:"5/3/2010", values:400}, 
        {category:"5/4/2010", values:200}, 
        {category:"5/5/2010", values:5000}
    ];
    
    var mychart = new Y.Chart({dataProvider:myDataValues, render:"#mychart"});
});

The dataProvider attribute accepts either an array of object literals or a multi-dimensional array. Below is an alternative dataProvider source for the above chart.

var myDataValues = [
    ["5/1/2010", "5/2/2010", "5/3/2010", "5/4/2010", "5/5/2010"],
    [2000, 50, 400, 200, 5000]
];
