<h3>Creating a chart <code>Chart</code> with multiple series.</h3>
<h4>Implementation</h4>
<p>Often times, you will want to plot multiple sets of data, or series, across the same category or range axis in a chart. This can be accomplished by changing your <code>dataProvider</code> source appropriately.</p>
<h4>CSS</h4>
<pre class="code prettyprint">#mychart {
margin:10px 10px 10px 10px;
width:90%;
max-width: 800px;
height:400px;
}</pre>
<h4>HTML</h4>
<pre class="code prettyprint"><div id="mychart"></div></pre>
<h4>JavaScript</h4>
<pre class="code prettyprint">YUI().use('charts', function (Y)
{
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"});
});</pre>
<p>The only difference between the above code and the previous example is that the <code>dataProvider</code> array has more records.</p>
<p>The chart application will plot all records that match it's <code>categoryKey</code> attribute along the category axis.
All other records will be plotted as series against the value axis. By default a chart's <code>categoryKey</code> is "category". This can be changed, if
necessary, to match the format of your <code>dataProvider</code> array. For example, if the key value for your dates was "date", you would need to change
the chart's <code>categoryKey</code> to "date".</p>
<pre class="code prettyprint">YUI().use('charts', function (Y)
{
var myDataValues = [
{date:"5/1/2010", miscellaneous:2000, expenses:3700, revenue:2200},
{date:"5/2/2010", miscellaneous:50, expenses:9100, revenue:100},
{date:"5/3/2010", miscellaneous:400, expenses:1100, revenue:1500},
{date:"5/4/2010", miscellaneous:200, expenses:1900, revenue:2800},
{date:"5/5/2010", miscellaneous:5000, expenses:5000, revenue:2650}
];
var mychart = new Y.Chart({dataProvider:myDataValues, render:"#mychart", categoryKey:"date"});
});</pre>
<p>By default, all remaining key values in your object literals will plot as series data on the chart. If you want to restrict the data that plots on a chart,
you can do so by setting the <code>seriesKeys</code> attribute. The below line of code would only display the expenses and revenue.</p>
<pre class="code prettyprint">var mychart = new Y.Chart({
dataProvider:myDataValues,
render:"#mychart",
categoryKey:"date",
seriesKeys:["expenses", "revenue"]
});</pre>
