词云图使用

1、安装
npm install echarts --save
npm install echarts-wordcloud --save
2、使用

1、在angular.json中引入
"scripts": [
    "../node_modules/echarts/dist/echarts.js",
    "../node_modules/echarts-wordcloud/dist/echarts-wordcloud.js" 
 ]
2、注入NgxEchartsModule 
import { NgxEchartsModule } from 'ngx-echarts';
3、使用的模块js中引入echarts-wordcloud
import 'echarts-wordcloud';
4、html中
<div echarts [options]="chartOption" style=" 560px; height: 560px;"></div>
5、ts中
chartOption: any;
  buildKeyword() {
    const option = {
      tooltip: {
          show: true
      },
      series: [{
          type: "wordCloud",
          800,
          height:500,
          textStyle: {
              normal: {
                  color: function() {
                      return 'rgb(' + [
                          Math.round(Math.random() * 160),
                          Math.round(Math.random() * 160),
                          Math.round(Math.random() * 160)
                      ].join(',') + ')';
                  }
              },
              emphasis: {
                  shadowBlur: 10,
                  shadowColor: '#333'
              }
          },
          data: [{
                  name: " 没有",
                  value: 30,
              },
              {
                  name: " 屏幕",
                  value: 24
              },
              {
                  name: " 不错",
                  value: 21
              },
              {
                  name: " 可以",
                  value: 19
              }
          ],
      }]
  };
  this.chartOption = option;
 }
（为减小长度，数据量少些，要更好的效果可以多加几条数据）

3、自定义词云图形状
