我是 Enyo(TouchPad) 的新开发人员。我想开发一个包含一些图表的应用程序。所以我正在尝试在 Enyo 中使用 Dojo 框架库。
谁能帮助我如何将dojo代码包含在我的应用程序中。我正在发布我的代码，请看一下。

.js 文件::
enyo.kind({
name: "CanvasDemo",
kind: enyo.Control,
nodeTag: "canvas",
domAttributes: {
width:"300px",
height:"300px",
style: "border: 2px solid #000;"
},
// After the canvas is rendered
rendered: function() {
// I want to place the dojo code here to display a chart in the canvas.
}
});
道场代码::
dojo.require('dojox.charting.Chart2D');
dojo.require('dojox.charting.widget.Chart2D');
dojo.require('dojox.charting.themes.Tom');
/* JSON information */
var json = {
January: [12999,14487,19803,15965,17290],
February: [14487,12999,15965,17290,19803],
March: [15965,17290,19803,12999,14487]
};
/* build pie chart data */
var chartData = [];
dojo.forEach(json['January'],function(item,i) {
chartData.push({ x: i, y: json['January'][i] });
});
/* resources are ready... */
dojo.ready(function() {
var chart2 = new dojox.charting.Chart2D('chart2').
setTheme(dojox.charting.themes.Tom).
addPlot('default', {type: 'Pie', radius: 70, fontColor: 'black'}).
addSeries('Visits', chartData).
render();
var anim = new dojox.charting.action2d.MoveSlice(chart2, 'default');
chart2.render();
});
请帮助我如何修改dojo代码，以便它可以在enyo中工作..
提前致谢。
问候，哈利。

chart1.render();
// var legend4 = new dojox.charting.widget.Legend({ chart: chart1 }, 'legend3');

});
这里我不确定如何调用enyo中的dojo代码。
和
依赖.js：
enyo.depends(
"source/charts1.js",
"lib/Chart2D.js",
"lib/widget/Chart2D.js",
"lib/blue.js",
"lib/dojo.js"
);
现在我收到以下错误：
error: Uncaught ReferenceError: dojo is not defined, Chart2D.js:1
[20110818-09:33:13.136736] error: Uncaught ReferenceError: dojo is not defined, widget/Chart2D.js:1
[20110818-09:33:13.138227] error: Uncaught ReferenceError: dojo is not defined, blue.js:1
[20110818-09:33:13.150707] error: Uncaught TypeError: Cannot read property 'graphs2' of undefined, index.html:10
当我在浏览器中将其用作具有相同代码的 .HTML 文件时，它工作正常。

请帮助我在 Enyo 中处理这个问题。感谢您。
亲切的问候，哈利。
