Charts: Create Stacked Chart

This example shows how to create a Stacked Column Chart.

A Stacked Chart is one in which its series are plotted cumulatively against a value axis. Stacked Charts are often used to compare the contribution of each series across categories. In the previous example, we made a column chart. In this example, we're going use the stacked attribute to change it to a Stacked Column Chart.

var myDataValues = [ 
    {category:"5/1/2010", miscellaneous:2000, expenses:3700, revenue:2200}, 
    {category:"5/2/2010", miscellaneous:50, expenses:9100, revenue:100}, 
    {category:"5/3/2010", miscellaneous:400, expenses:1100, revenue:1500}, 
    {category:"5/4/2010", miscellaneous:200, expenses:1900, revenue:2800}, 
    {category:"5/5/2010", miscellaneous:5000, expenses:5000, revenue:2650}
];
 
var mychart = new Y.Chart({
                    dataProvider:myDataValues, 
                    render:"#mychart", 
                    type:"column", 
                    stacked:true
                });

var myDataValues = [ 
    {category:"5/1/2010", miscellaneous:2000, expenses:3700, revenue:2200}, 
    {category:"5/2/2010", miscellaneous:50, expenses:9100, revenue:100}, 
    {category:"5/3/2010", miscellaneous:400, expenses:1100, revenue:1500}, 
    {category:"5/4/2010", miscellaneous:200, expenses:1900, revenue:2800}, 
    {category:"5/5/2010", miscellaneous:5000, expenses:5000, revenue:2650}
];
 
var mychart = new Y.Chart({
                    dataProvider:myDataValues, 
                    render:"#mychart", 
                    type:"column", 
                    stacked:true
                });

Technically, all charts plotted against x and y axes can be stacked. The following series types are most commonly and effectively displayed stacked:

• combo
• column
• bar
• area
• areaspline
• combospline
