# 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>
