jqplot不适用于动态数据

我正在尝试使用jqplot绘制从SQLite DB for Phonegap检索数据的条形图 – Android如何对db值使用相同的代码。 这个带有静态数据的代码在标签内工作正常，但是当我试图把这个代码放在$('#pageid').live('pageinit',function(){}); 然后它不起作用。 什么原因？

         var s1 = [10,0,0,0,0]; var s2 = [0,20,0,0,0]; var s3 = [0,0,30,0,0]; var s4 = [0,0,0,25,0]; var s5 = [0,0,0,0,0]; var ticks = ['FAJR', 'ZOHAR', 'ASR', 'MAGHRIB','ISHA']; var plot1 = $.jqplot('chart1', [s1, s2, s3,s4,s5], { // The "seriesDefaults" option is an options object that will // be applied to all series in the chart. seriesDefaults:{ title:'Namaz Vs MissingPrayer', renderer:$.jqplot.BarRenderer, rendererOptions: {fillToZero: true} }, series:[ {label:'Fajr'}, {label:'Z'}, {label:'A'}, {label:'M'}, {label:'I'} ], legend: { show: true, placement: 'outsideGrid' }, axes: { // Use a category axis on the x axis and use our custom ticks. xaxis: { renderer: $.jqplot.CategoryAxisRenderer, label:'NAMAZ', ticks: ticks, }, // Pad the y axis just a little so bars can get close to, but // not touch, the grid boundaries. 1.2 is the default padding. yaxis: { min:0, label:'MISSING PRAYERS', pad: 1.05, tickOptions: {formatString: '%d'} } } }); });
