A Bar chart demonstrating the axis options

This goes in the documents header:

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

Put this where you want the chart to show up:

<button onclick="obj = getObject(); obj.Set('xaxispos', obj.Get('xaxispos') == 'bottom' ? 'center' : 'bottom'); RGraph.Redraw();">Toggle the X axis position</button>
<button onclick="obj = getObject(); obj.Set('yaxispos', obj.Get('yaxispos') == 'left' ? 'right' : 'left'); RGraph.Redraw();">Toggle the Y axis position</button>
<button onclick="obj = getObject(); obj.Set('ylabels', obj.Get('ylabels') ? false : true); RGraph.Redraw();">Toggle the Y axis labels</button>
<button onclick="obj = getObject(); obj.Set('ylabels.specific', obj.Get('ylabels.specific') ? false : ['High','Medium','Low']); RGraph.Redraw();">Toggle specific Y axis labels</button>
<button onclick="obj = getObject(); obj.Set('ymin', obj.Get('ymin') ? 0 : 50); RGraph.Redraw();">Toggle ymin (50) setting</button>
<button onclick="obj = getObject(); obj.Set('labels', obj.Get('labels') ? null : ['Q1','Q2','Q3','Q4']); RGraph.Redraw();">Toggle labels</button>
<button onclick="obj = getObject(); obj.Set('noxaxis', obj.Get('noxaxis') ? false : true); RGraph.Redraw();">Toggle X axis</button>

<canvas id="cvs" width="600" height="400">
    [No canvas support]
</canvas>

This is the code that generates the chart:

<script>
    function getObject ()
    {
        return RGraph.ObjectRegistry.getFirstObjectByType('bar');
    }

    window.onload = function ()
    {
        var bar = new RGraph.Bar({
            id: 'cvs',
            data: [64,65,70,74],
            options: {
                ymax: 120,
                xmax: 365,
                labels: ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'],
                xaxispos: 'center',
                gutterBottom: 45,
                gutterLeft: 35,
                strokestyle: 'rgba(0,0,0,0)',
                textAccessible: true
            }
        }).draw();
    };
</script>
