在Titanium中如何画图表
目前版本的Titanium的一个弱点就是不能画图！这回我们说说通过flot在Titanium中画图表。
flot的下载
flot的主页：http://code.google.com/p/flot/
下载flot-0.7.zip后，把以下文件拷贝到自己的工程中：
jquery.flot.jsjquery.js
flot的测试
作成以下flot测试用的plot_window.js：
var win = Ti.UI.currentWindow;var webView = Ti.UI.createWebView({url: 'plot.html'});win.add(webView);<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Flot Examples</title> <link href="layout.css" rel="stylesheet" type="text/css"> <!--[if lte IE 8]><script language="javascript" type="text/javascript" src="../excanvas.min.js"></script><![endif]--> <script language="javascript" type="text/javascript" src="jquery.js"></script> <script language="javascript" type="text/javascript" src="jquery.flot.js"></script> </head> <body> <h1>Data Graph</h1> <div id="graph" style="width:310px;height:240px;"></div><script type="text/javascript">var weights = [[1301270400000,0],[1301875200000,8.25],[1302480000000,22],[1303084800000,29],[1303689600000,36.5]];var ticks = [1301270400000,1301875200000,1302480000000,1303084800000,1303689600000];var setting = { series: { lines: { show:true}, points: { show:true} }, xaxis: { mode:"time", timeformat:"%m/%d", tickSize: [7,"day"], ticks: ticks }, yaxis: { ticks: 10, min: 0, }, grid: { backgroundColor: { colors: ["#fff","#eee"] }, } };$.plot($("#graph"),[{data: weights, color: 2}], setting);</script> </body></html>
var graphButton = Ti.UI.createButton({title: 'Graph'});graphButton.addEventListener('click', function () {if (records.length > 0) {var weights = "[";var ticks = "[";for (i = records.length-1; i >= 0; i--) {weights = weights + "[" + records[i].at.getTime() +","+records[i].weight+"],";ticks = ticks + records[i].at.getTime() + ",";} weights = weights + "]"; ticks = ticks + "]";var graphWindow = Ti.UI.createWindow({url: 'plot_window.js',weights: weights,ticks: ticks});Ti.UI.currentTab.open(graphWindow);}});win.leftNavButton = graphButton;webView.addEventListener('load', function(){webView.evalJS('weights =' + win.weights + ';');webView.evalJS('ticks =' + win.ticks + ';');webView.evalJS('setting.xaxis.ticks = ticks;');webView.evalJS('$.plot($("#graph"),[{data: weights, color: 2}], setting);');});
