在DOJO中自定義餅圖切片

Question

我使用Dojo 1.6生成動態圖表。在這裏，我需要將數字百分比（％）放在相應圖表切片之外，因爲我得到了以下餅圖。

用於上述圖表代碼..

dojo.xhrPost({ 
      url :"/ritl/chart/getModelPieDataForAll.htm", 
      handleAs : "json", 
      load : function(response, ioargs) { 
      require([ 
      "dojox/charting/Chart", 
      "dojox/charting/themes/MiamiNice", 
      "dojox/charting/plot2d/Pie", 
      "dojox/charting/action2d/Tooltip", 
      "dojox/charting/action2d/MoveSlice", 
      "dojo/colors", 
      "dojox/charting/plot2d/Markers", 
      "dojox/charting/axis2d/Default", 
      "dojo/domReady!" ], 
      function(Chart, theme, Pie, Tooltip, MoveSlice,Legend) { 
       var chart = new Chart("chartForModel",{ 
        title: "Model Pie Chart", 
        titlePos: "bottom", 
        titleGap: 25, 
        titleFont: "normal normal normal 15pt Arial", 
        titleFontColor: "black" 
       }); 
      chart.setTheme(dojox.charting.themes.MiamiNice); 
      chart.addPlot("default", { 
        type : Pie, 
        markers : true, 
        radius : 100 
       }); 
      chart.addAxis("x"); 
      chart.addAxis("y", {min : 100, max : 10000, vertical : true, fixLower : "major", fixUpper : "major"}); 
      chart.addSeries("Sales Product - 2013", response.data); 
      chart.render(); 
      new dojox.charting.widget.Legend({ 
       chart : chart, 
       horizontal : true 
       }, "legend1"); 
      }); 
     }, 
    error : function(response, ioargs) {console.log("Inside Handle Error"); 
    } 
}); 

Answer 1

添加labelOffset：到chart.addPlot。

例如chart.addPlot("default", { type : Pie, markers : true, labelOffset: -17, radius : 100 });
