Chart.js 在饼图上显示标签 [英] Chart.js Show labels on Pie chart
问题描述
我最近将我的 charts.js 库更新到了最新版本 (2.5.0).此版本不显示图表上的标签.
我有一个在 fiddler 上工作的例子:
似乎没有这样的内置选项.
然而,这个选项有一个特殊的库,它调用:"Chart PieceLabel".
这是他们的演示.
将他们的脚本添加到您的项目后,您可能需要添加另一个选项,称为:pieceLabel",并根据需要定义属性值:
pieceLabel: {//模式 'label'、'value' 或 'percentage',默认为 'percentage'模式:(!模式)?值":模式,//百分比精度,默认为0精度:0,//字体大小,默认为defaultFontSize字体大小:18,//字体颜色,默认为'#fff'fontColor: '#fff',//字体样式,默认为defaultFontStylefontStyle: '粗体',//字体系列,默认为 defaultFontFamilyfontFamily:'Helvetica Neue'、'Helvetica'、'Arial'、无衬线字体"}
I recently updated my charts.js library to the most updated version (2.5.0). This version doesn't show the labels on the chart.
I have an example of working one on fiddler: http://jsfiddle.net/g6fajwg8 .
However, I defined my chart exactly as in the example but still can not see the labels on the chart.
Note: There are a lot of questions like this on Google and Stackoverflow but most of them are about previous versions which is working well on them.
var config = {
type: 'pie',
data: {
datasets: [{
data: [
1200,
1112,
533,
202,
105,
],
backgroundColor: [
"#F7464A",
"#46BFBD",
"#FDB45C",
"#949FB1",
"#4D5360",
],
label: 'Dataset 1'
}],
labels: [
"Red",
"Green",
"Yellow",
"Grey",
"Dark Grey"
]
},
options: {
responsive: true,
legend: {
position: 'top',
},
title: {
display: true,
text: 'Chart.js Doughnut Chart'
},
animation: {
animateScale: true,
animateRotate: true
}
}
};
window.pPercentage = new Chart(ChartContext, config);
It seems like there is no such build in option.
However, there is special library for this option, it calls: "Chart PieceLabel".
Here is their demo.
After you add their script to your project, you might want to add another option, called: "pieceLabel", and define the properties values as you like:
pieceLabel: {
// mode 'label', 'value' or 'percentage', default is 'percentage'
mode: (!mode) ? 'value' : mode,
// precision for percentage, default is 0
precision: 0,
// font size, default is defaultFontSize
fontSize: 18,
// font color, default is '#fff'
fontColor: '#fff',
// font style, default is defaultFontStyle
fontStyle: 'bold',
// font family, default is defaultFontFamily
fontFamily: "'Helvetica Neue', 'Helvetica', 'Arial', sans-serif"
}
