// categories is the data on the top of the scree开发者_JS百科nshot.

    $.jqplot('timeOffGraph', hours, {
                    seriesDefaults: {
                        renderer: $.jqplot.BarRenderer,
                        rendererOptions: { fillToZero: true },
                        pointLabels: { show: true }
                    },
                    axes: {
                        xaxis: {
                            renderer: $.jqplot.CategoryAxisRenderer,
                            ticks: categories
                        },
                        yaxis: {
                            tickOptions: { formatString: '%d' },
                            autoscale: true,
                            min: 0,
                            max: 10000
                        }
                    }
                });

I get "DataError: no data to plot"

I think you need to put it in one more array $.jqplot('timeOffGraph', [hours], {
