dojo chart生成函数,
前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
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
