    <h1>A Line chart with different colors above a certain point</h1>
    
    <p>
        A Line chart with different colors above a certain point. It uses a filled range chart to achieve this effect.

    <canvas id="cvs" width="600" height="250">[No canvas support]</canvas>

    <p>
        <b>Update</b><br />
        There's information <a href="http://www.rgraph.net/docs/howto-dynamic-line-chart.html">on this HOWTO page</a> about creating dual color line
        charts using
        gradients. It's <b>very</b> simple and can be done using either the
        RGraph Gradient() shortcut or more directly with the canvas  linear gradient functionality.

        window.onload = function ()

                 d1[i] = d1[i] - 0.2; // The +/- 0.2 determines the width of the line
                 d2[i] = d1[i] + 0.2;
            }

        
            var line = new RGraph.Line({
                id: 'cvs',

    This goes in the documents header:
    <pre class="code">
&lt;script src="RGraph.common.core.js"&gt;&lt;/script&gt;
&lt;script src="RGraph.line.js"&gt;&lt;/script&gt;
</pre>
    
    Put this where you want the chart to show up:
    <pre class="code">
&lt;canvas id="cvs" width="600" height="250"&gt;
    [No canvas support]
&lt;/canvas&gt;
</pre>

    This is the code that generates the chart:
    <pre class="code">
&lt;script&gt;
    window.onload = function ()
    {
        var d1  = [1,4,8,5,2,3,6,5,15,16,12,13,18,19,15,16];
        var d2  = [];
        
        <span>// Create the data</span>
        for (var i=0; i&lt;d1.length; i+=1) {
             d1[i] = d1[i] - 0.2; // The +/- 0.2 determines the width of the line
             d2[i] = d1[i] + 0.2;
        }

    
        var line = new RGraph.Line({
            id: 'cvs',
            data: [d1, d2],
            options: {
                backgroundGridAutofitNumhlines: 5,
                backgroundGridAutofitNumvlines: 15,
                filled: true,
                filledRange: true,
                filledRangeThreshold: 10,
                filledRangeThresholdColors: ['red', 'blue'],
                labels: ['A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P'],
                colors: ['transparent', 'transparent'],
                numxticks: 15,
                tickmarks: null,
                textAccessible: true
            }
        }).draw();
    };
&lt;/script&gt;
</pre>
