-- 曲线图

var labels = ["x1",“x2”,“x3”,“x4”,“x5”,“x6”];

var series = [1,2,3,4,5,6,];

var initUsageChartChart = function(labels,series){

var userChart = new dojox.charting.Chart("Usage_Chart");

userChart.addAxis("x",{
labels: labels,
majorTick: { color: "black",length: 2 },//X轴大刻度的颜色、长度
minorTick: { stroke: "black",length: 2},//X轴小刻度的颜色、长度
rotation: 45
});

userChart.addAxis("y",{
vertical: true,
fixLower : "major",
fixUpper : "major"
});

userChart.addplot("default",{
type: "Lines",
markers : true,
});

// 填充数据

userChart.addSeries("Usage Line",series,{ stroke: "blue",fill: "white" });

// 添加特效

new dojox.charting.widget.Legend(userChart,"legend");
new dojox.charting.action2d.Magnify(userChart,"default");
new dojox.charting.action2d.Tooltip(userChart,"default");

// 渲染

userChart.render();

};

-- 画柱状图

var createColumnChart = function(){
columnChart = new dojox.charting.Chart("usage_chart");

// 增加x轴
columnChart.addAxis("x",{
labels: labels
});

//增加Y轴，也不需要显示
columnChart.addAxis("y",{
vertical : true,
fixUpper : "major"
});

//定义图标类型，这里是柱状图
columnChart.addplot("default",{
type : "StackedColumns",
markers : true,
gap : 10,
animate: { duration: 3000 }
});

columnChart.addSeries(“column”,{ stroke: { color: "blue",width: 2 },fill: "blue" });

//渲染
columnChart.render();

new dojox.charting.action2d.Tooltip(columnChart,"default");
new dojox.charting.action2d.Highlight(columnChart,"default");
new dojox.charting.action2d.Shake(columnChart,"default",{shiftY: 0});
};

-- Grid
