我是初学者尝试使用 DOjo 绘制图表示例。这是我从这个论坛中挑选的代码。我可以看到图表,但根本看不到图例...
是小部件声明中的错误还是缺少某些文件?虽然所有文件都在我的系统中可用..我彻底迷路了..
dojo.require("dojox.charting.Chart2D");
dojo.require("dojox.charting.Chart2D");
dojo.require("dojox.charting.themes.PlotKit.blue");
dojo.require("dojox.charting.widget.Legend");
dojo.require("dojox.layout.FloatingPane");
dojo.require("dojox.charting.themes.MiamiNice");
dojo.require("dojo.colors");
makeCharts = function() {
var chart1 = new dojox.charting.Chart2D("simplechart");
chart1.addPlot("default", {
type: "StackedColumns",
markers: true,
tension: 3,
shadows: {
dx: 2,
dy: 2,
dw: 2
}
});
chart1.addAxis("x", {
labels: [{
value: 1,
text: '18-Mar'
}, {
value: 2,
text: '19-Mar'
}, {
value: 3,
text: '20-Mar'
}, {
value: 4,
text: '21-Mar'
}, {
value: 5,
text: '22-Mar'
}, {
value: 6,
text: '23-Mar'
}]
});
chart1.addAxis("y", {
vertical: true
});
chart1.addSeries("Four", [196, 209, 77, 218, 48, 243]);
chart1.addSeries("One", [266, 158, 131, 228, 217, 262]);
chart1.addSeries("Three", [296, 214, 267, 80, 40, 225]);
chart1.addSeries("Two", [207, 264, 115, 227, 193, 27]);
chart1.setTheme(dojox.charting.themes.MiamiNice);
chart1.render();
var legend = new dojox.charting.widget.Legend({
chart: chart1,
horizontal: true
}, "legend");
};
dojo.addOnLoad(makeCharts);
