我正在使用Chart.js添加餅圖。我可以顯示圖表，但想顯示標籤，百分比和圖例。向圖表添加標籤js餅圖
有誰知道如何做到這一點？
這裏是我是如何生成餅圖：
dashboardRegion: (survey) ->
male = 0
female = 0
survey.get('responses').each (response) ->
if response.get('completed')
if response.get('gender') == "male"
male += 1
else
female += 1
genderData = [
{
value: male,
color:"#9A3334",
highlight: "#9A3334",
label: "Male",
labelFontFamily : "Arial",
labelFontStyle : "normal",
labelFontSize : 24,
labelFontColor : "#666"
},
{
value: female,
color: "#217C7E",
highlight: "#217C7E",
label: "Female",
labelFontFamily : "Arial",
labelFontStyle : "normal",
labelFontSize : 24,
labelFontColor : "#666"
}
];
