A black and white Line chart

This goes in the documents header:

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

Put this where you want the chart to show up:

<canvas id="cvs" width="700" height="250">
    [No canvas support]
</canvas>

This is the code that generates the chart:

<script>
    var line = new RGraph.Line({
        id: 'cvs',
        data: [0,10,46,13,74,100,51],
        options: {
            linewidth: 7,
            colors: ['black'],
            shadow: false,
            tickmarks: 'filledcircle',
            numxticks: 0,
            numyticks: 0,
            axisLinewidth: 7,
            ticksize: 15,
            gutterLeft: 125,
            gutterRight: 5,
            gutterBottom: 25,
            gutterTop: 20,
            backgroundGrid: false,
            ylabelsSpecific: ['100%  ', '50%  ', '0%  '],
            textSize: 24,
            textFont: 'Verdana',
            hmargin: 35,
            textAccessible: true,
            ylabelsOffsetx: -25
        }
    
    // Draw the "tails" to the axes
    }).on('draw', function (obj)
    {
        // This function draws the little ends to the axes
        RGraph.path2(
            obj.context,
            'b lw 7 m % % l % % m % % l % % s black',
            obj.gutterLeft, obj.canvas.height - obj.gutterBottom,
            obj.gutterLeft - 15, obj.canvas.height - obj.gutterBottom,
            obj.gutterLeft, obj.canvas.height - obj.gutterBottom,
            obj.gutterLeft, obj.canvas.height - obj.gutterBottom + 15
        );
    }).trace2({frames: 60});
