Title
How to display a word cloud on top of the outer container?
Description
We have a relatively small scene displaying word clouds, hoping to make the word cloud fill the entire container as much as possible. I tried the official website, but it seems that it cannot fill the container
Solution
This is because in VChart, the word cloud is defaulted to use 'circle 'circular markShape mask graphics, if you want to fill the container as much as possible, you can use 'rect'shape.
Code example
const spec = {
type: 'wordCloud',
nameField: 'Keyword',
valueField: 'Score',
data: {
name: 'baseData',
values: [ { "Keyword": "预期寿命", "Score": 0.8571 }, { "Keyword": "心率", "Score": 0.8571 }, { "Keyword": "疾病", "Score": 0.7597 }, { "Keyword": "心跳快慢", "Score": 0.5714 }, { "Keyword": "心跳", "Score": 0.5714 }, { "Keyword": "郭艺芳", "Score": 0.5624 }, { "Keyword": "陈清勇", "Score": 0.5624 }, { "Keyword": "风险因素", "Score": 0.4874 }, { "Keyword": "心动过速", "Score": 0.4874 }, { "Keyword": "寿命", "Score": 0.3849 }, { "Keyword": "快慢", "Score": 0.3844 }, { "Keyword": "生活习惯", "Score": 0.2857 }, { "Keyword": "河北省人民医院", "Score": 0.2857 }, { "Keyword": "四川大学华西医院", "Score": 0.2186 }, { "Keyword": "华西医院", "Score": 0.2121 }, { "Keyword": "阿尔茨海默病", "Score": 0.2067 }, { "Keyword": "人群", "Score": 0.1984 }, { "Keyword": "痴呆", "Score": 0.19 }, { "Keyword": "研究", "Score": 0.1761 }, { "Keyword": "健康", "Score": 0.1754 }, { "Keyword": "习惯", "Score": 0.1709 }, { "Keyword": "医院", "Score": 0.1664 }, { "Keyword": "风险", "Score": 0.1647 }, { "Keyword": "心内科", "Score": 0.16 }, { "Keyword": "生活", "Score": 0.158 }, { "Keyword": "工作", "Score": 0.1554 }, { "Keyword": "心血管疾病", "Score": 0.1299 }, { "Keyword": "咖啡", "Score": 0.0974 }, { "Keyword": "志飞", "Score": 0.0974 }, { "Keyword": "中国妇女报", "Score": 0.0974 }, { "Keyword": "人民医院", "Score": 0.0913 } ]
},
maskShape: 'rect',
width: 400,
height: 300,
background: '#cccc',
padding: 10
};
const vchart = new VChart(spec, { dom: CONTAINER_ID });
vchart.renderSync();
// Just for the convenience of console debugging, DO NOT COPY!
window['vchart'] = vchart;
