• 好看的echart的词云效果(wordCloud)





    基础的设置:


    series: [{
    name: '',
              type: 'wordCloud',
              shape: 'circle',
              rotationRange: [0,0],//字体旋转的角度
              sizeRange: [12, 50],//字体大小的范围
              gridSize: 10,//字体分布的密集程度
              maskImage: maskImage,//字体以图片形状分布,支持为 HTMLImageElement, HTMLCanvasElement,不支持路径字符串
              textStyle: {
    normal: {
                  fontFamily: 'sans-serif',
                      //fontWeight: 'bold',
                      // Color can be a callback function or a color string
                      color: function () {
                          // Random color
                          return 'rgb(' + [
                              Math.round(Math.random() * 160),
                              Math.round(Math.random() * 160),
                              Math.round(Math.random() * 160)
                          ].join(',') + ')';//字体的随机颜色
                      }
                  },
                  emphasis: {//鼠标移入的特效样式
                      shadowBlur: 10,
                      shadowColor: '#333'
                  }
              },
              data:[
              ],
    }]
     
      vue项目使用的 ,引入的一个圆形图片   

        var
    maskImage = new Image(); //重点:图片的base64码,我用的png图片 maskImage.src = require('../../../assets/img/yuan_icon.png');
        
    给图表加个涟漪似的动画效果的背景
    把.
    circle-ripple元素固定到图表后面即可,下面是样式表
    $color:#bdd2f6;
    .circle-ripple {
      background-color:$color;
       72%;
        height: 400px;
        font-size: 12px;
        border-radius: 50%;
        position: absolute;
        top:50%;
        left:50%;
        transform: translate(-50%, -50%);
      animation: ripple 0.7s linear infinite;
    }
    @keyframes ripple {
      0% {
        box-shadow: 0 0 0 0 rgba($color, 0.3),
                    0 0 0 1em rgba($color, 0.3),
                    0 0 0 3em rgba($color, 0.3),
                    // 0 0 0 5em rgba($color, 0.3);
      }
      100% {
        box-shadow: 0 0 0 1em rgba($color, 0.3),
                    0 0 0 3em rgba($color, 0.3),
                    0 0 0 5em rgba($color, 0),
                    // 0 0 0 8em rgba($color, 0);
      }
    }
