Advanced tools
npm install wywordcloud --save
<div style="zoom:0.5" id="container"><div>
import Wywordcloud from 'wywordcloud';
var wc = new Wywordcloud(document.getElementById('container'))
wc.setOption({
tooltip: {
show: true
},
list: [['谈笑风生', 80], ['谈笑风生', 80], ['谈笑风生', 70], ['谈笑风生', 70], ['谈笑风生', 60], ['谈笑风生', 60]],
color: '#15a4fa'
})
(1)data:词云生成数据,包含具体词语以及频率;
(2)size:字体大小,默认为1,一般来说该值越小,生成的形状轮廓越明显;
(3)fontFamily:字体,如‘微软雅黑’;
(4)fontWeight:字体粗细,包含‘normal’,‘bold’以及‘600’;;
(5)color:字体颜色,可以选择‘random-dark’以及‘random-light’,其实就是颜色色系,也可以使用 回调函数 对每个词语 进行颜色选择 callback(word, weight, fontSize, distance, theta);
(6)backgroundColor:背景颜色,支持R语言中的常用颜色,如‘gray’,‘blcak’,但是还支持不了更加具体的颜色选择,如‘gray20’;
(7)minRontatin与maxRontatin:字体旋转角度范围的最小值以及最大值,选定后,字体会在该范围内随机旋转;
(8)rotationRation:字体旋转比例,如设定为1,则全部词语都会发生旋转;
(9)shape:词云形状选择,默认是‘circle’,即圆形。还可以选择‘cardioid’(苹果形或心形),‘star’(星形),‘diamond’(钻石),‘triangle-forward’(三角形),‘triangle’(三角形),‘pentagon’(五边形)
setOption(options)
options必须通过此API进行设置,才能显示词云
在wordcloud2.js原options基础上增加:
{
// ...
imageShape: 'https://example.com/images/shape.png', // 提供一张图片,根据其形状进行词云渲染,默认为null
fontSizeFactor: 0.1, // 当词云值相差太大,可设置此值进字体行大小微调,默认0.1
maxFontSize: 60, // 最大fontSize,用来控制weightFactor,默认60
minFontSize: 12, // 最小fontSize,用来控制weightFactor,默认12
isShowBackShape: false, // 是否显示背景图形
tooltip: {
show: true, // 默认:false
backgroundColor: 'rgba(0, 0, 0, 0.701961)', // 默认:'rgba(0, 0, 0, 0.701961)'
formatter: function(item) { // 数据格式化函数,item为list的一项
}
},
noDataLoadingOption: { // 无数据提示。
backgroundColor: '#eee',
text: '暂无数据',
textStyle: {
color: '#888',
fontSize: 14
}
}
// ...
}
showLoading([loadingOption])
过渡控制,显示loading(读取中)。可选。
loadingOption
:
{
backgroundColor: '#eee',
text: '正在加载...',
effect: 'spin' // 默认:null, { String | Function } 可选:'spin|normal';也可为回调函数,回调函数生成HTML
}
hideLoading()
隐藏loading
resize()
当容器大小变化时,调用此方法进行重绘
