    /**
     * Class: $.jqplot.OHLCRenderer
     * jqPlot Plugin to draw Open Hi Low Close, Candlestick and Hi Low Close charts.
     * 
     * To use this plugin, include the renderer js file in 
     * your source:
     * 
     * > <script type="text/javascript" src="plugins/jqplot.ohlcRenderer.js"></script>
     * 
     * You will most likely want to use a date axis renderer
     * for the x axis also, so include the date axis render js file also:
     * 
     * > <script type="text/javascript" src="plugins/jqplot.dateAxisRenderer.js"></script>
     * 
     * Then you set the renderer in the series options on your plot:
     * 
     * > series: [{renderer:$.jqplot.OHLCRenderer}]
     * 
     * For OHLC and candlestick charts, data should be specified
     * like so:
     * 
     * > dat = [['07/06/2009',138.7,139.68,135.18,135.4], ['06/29/2009',143.46,144.66,139.79,140.02], ...]
     * 
     * If the data array has only 4 values per point instead of 5,
     * the renderer will create a Hi Low Close chart instead.  In that case,
     * data should be supplied like:
     * 
     * > dat = [['07/06/2009',139.68,135.18,135.4], ['06/29/2009',144.66,139.79,140.02], ...]
     *
