写了一个函数，就是通过传递参数，生成图表，代码如下：
/**
* created by LZUGIS
* @param container
* @param type
* @param data
* @constructor
*/
function AddChart(container, type, data){
require([
"dojox/charting/Chart2D",
"dojox/charting/themes/PlotKit/blue",
"dojox/charting/action2d/Highlight",
"dojox/charting/action2d/Tooltip",
"dojox/charting/action2d/MoveSlice"
], function(
Chart2D,
themes,
Highlight,
Tooltip,
MoveSlice
){
var chart = new dojox.charting.Chart2D(container);
chart.setTheme(dojox.charting.themes.PlotKit.blue);//设置主题
switch(type){
case "bar":{//柱状图
chart.addPlot("default", {
type: "Columns",
gap: 8//控制柱子之间的间隔
});
break;
}
case "pie":{//饼状图
chart.addPlot("default", {
type: "Pie",
labelOffset: 40//控制标注显示位置，“+”为里面，“-”为外面
});
break;
}
case "line":{//线形图
chart.addPlot("default", {
type: "Lines",
markers:true,//数据点是否显示
tension:"X"//曲线圆滑，"X"与“S”类似，“x”为闭合圆滑
});
break;
}
case "stack":{//堆积图
chart.addPlot("default",{
type: "StackedColumns",
gap: 8
});
break;
}
default :{
break;
}
}
var xStr = ["周一","周二","周三","周四","周五","周六","周日"];
// Add axes
var myLabelFunc = function(text, value, precision){
return xStr[text-1];
};
chart.addAxis("x", { labelFunc: myLabelFunc });
chart.addAxis("y", { vertical:true, fixLower: "major", fixUpper: "major" });
chart.addSeries("Series A", data);
new Highlight(chart, "default", {highlight: "lightskyblue"});
new Tooltip(chart, "default");
new MoveSlice(chart, "default");
// new Legend({chart: chart}, "legend");
chart.render();
});
}
使用方法很简单，如下：
