A Line chart showing employee sales

A Line chart showing the employee sales by department. Since this chart is a copy of a chart found on the Internet it uses the Line chart - though a stacked or grouped Bar chart may represent the data better because the types of furniture aren't related to each other.

This goes in the documents header:

<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.key.js"></script>
<script src="RGraph.line.js"></script>

Put this where you want the chart to show up:

<div style="text-align: center">
    <canvas id="cvs" width="575" height="450">[No canvas support]</canvas>
</div>

This is the code that generates the chart - it should be placed AFTER the canvas tag(s):

<script>
    // Create the Line chart
    new RGraph.Line({
        id: 'cvs',
        
        // The four datasets that are shown on the chart - a multi-dimensional
        // array.
        data: [
            [190,165,47,121,30,72],
            [12,180,10,80,25,75],
            [42,80,93,25,21,120],
            [2,42,27,47,43,50]
        ],

        options: {
            shadow: false,
            tickmarksStyle: null,
            backgroundGridVlines: false,
            backgroundGridColor: 'gray',
            colorsBackground: '#222',
            xaxis: false,
            yaxis: false,

            textSize: 14,
            title: '2009 employee sales by department',
            titleColor: 'white',

            marginLeft: 50,

            marginBottom: 60,
            colors: ['#B8202C','#96D1E3','#FA8710','#62648D'],
            
            // The key for this chart is positioned in the bottom margin
            // instead of the top
            key: ['Mary','Tom','Brad','Kate'],
            keyPosition: 'margin',
            keyLabelsSize: 14,
            keyLabelsColor: 'rgb(248,248,248)',
            keyPositionY: 425,
            responsive: [
                {maxWidth:null,width:575,height:450,options:{linewidth: 7,marginTop: 75,titleSize: 17,keyPositionY: 425},css:{'float':'none'}},
                {maxWidth:900,width:400,height:300,options:{linewidth: 4,marginTop: 55,titleSize: 17,keyPositionY: 275},css:{'float':'none'}}
            ]
        }
    
    // Here we use the beforedraw event to clear the canvas to a dark
    // color before the drawing is performed. Since it's the beforedraw
    // event the call to the draw() function has to be after the on()
    // function (otherwise the beforedraw event would have already run
    // by the time that the event is added.
    }).on('beforedraw', function (obj)
    {
        // Clear the canvas to a specific color
        RGraph.clear(obj.canvas, '#555557');

    // Use the trace effect to show the chart and add some responsive capability to accommodate
    // smaller screens.
    }).trace();
