今天,我们采用echarts数据可视化图形来做一个简单的数据可视化页面。

其中,涉及到一些css文件、js文件等等,都可以在这个博主的github上下载到,路过的小伙伴欢迎star!!

Echarts-Demo/css at master · nichan-13/Echarts-Demo · GitHub,从github上下载好文件之后,只需要放在相应位置就可以了。

如果有什么地方代码不清楚不明白的,可以看看这个老师的b站视频,强烈安利,老师讲的很详细!!!ECharts数据可视化项目-大屏数据可视化展示-echarts 图表制作-pink老师直播课更新完毕)_哔哩哔哩_bilibili

  

 步骤:

1、先布置框架,代码文件的框架为:

winform数据可视化控件 数据可视化界面_javascript

2、制作echarts可视化看板的“head”头部部分:

其中包括两个部分:

  • 整个echarts可视化看板的标题
  • 展示当前的时间

(1)css文件中的head头部代码部分为:

// css 初始化
* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
  // overflow: hidden;
}

li {
  list-style: none;   // 去掉前面的圆点
}

// 声明字体
@font-face {
  font-family: electronicFont;
  src: url(../font/DS-DIGIT.TTF);
}


body {
  background: url(../images/bg.jpg) no-repeat top center;
  line-height: 1.15;
}

header {
  position: relative;
  height: 1.25rem;
  background: url(../images/head_bg.png) no-repeat;
  background-size: 100% 100%;

  h1 {
    font-size: .475rem;
    color: rgba(255, 255, 255, 0.87);
    text-align: center;
    line-height: 1rem;
  }

  .show-time {
    position: absolute;
    top: 0;
    right: .375rem;
    line-height: .9375rem;
    color: rgba(255, 255, 255, 0.7);
    font-size: 0.25rem;
  }
}

(2)html文件中的head头部代码部分为: 

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>数据可视化</title>
    <link rel="stylesheet" href="css/index.css" />
  </head>
  <body>
    <!-- 头部 -->
    <header>
      <h1>数据可视化-ECharts</h1>
      <div class="show-time"></div>
      <script>
        // 格式:当前时间:2022年5月3日-13时20分24秒
        var t = null;
        t = setTimeout(time, 1000); //开始运行
        function time() {
          clearTimeout(t); //清除定时器
          dt = new Date();
          var y = dt.getFullYear();
          var mt = dt.getMonth() + 1;
          var day = dt.getDate();
          var h = dt.getHours(); //获取时
          var m = dt.getMinutes(); //获取分
          var s = dt.getSeconds(); //获取秒
          document.querySelector(".show-time").innerHTML = "当前时间:" + y + "年" + mt + "月" + day + "日-" + h + "时" + m + "分" + s + "秒";
          t = setTimeout(time, 1000); //设定定时器,循环运行
        }
      </script>
    </header>
  </body>
</html>

(3)浏览器显示的页面效果:

winform数据可视化控件 数据可视化界面_echarts_02

 3、布局“页面主体盒子”部分

其中包括几个部分:

  • 左边盒子包含三个echarts可视化图
  • 中间盒子放一个地图map
  • 右边盒子包含三个echarts可视化图

(1)css文件中的head头部代码部分为:

// 页面主体盒子
.mainbox {
  display: flex;
  min-width: 1024px;
  max-height: 1920px;
  margin: 0 auto;
  padding: .125rem .125rem 0;       // 上、左右边距

  .column {
    flex: 3;  // 整个页面分为三列
  }

  .column:nth-child(2) {
    flex: 5;
    margin: 0 .125rem .1875rem;  // 外边距
    // 图片旋转有时会超出屏幕最大位置导致滚动条自动上下移动
    overflow: hidden;
  }

  .panel {
    position: relative;
    height: 3.875rem;
    padding: 0 .1875rem .5rem;
    margin-bottom: .1875rem;  // 下外边距
    border: 1px solid rgba(25, 186, 139, 0.17);
    background: url(../images/line.png) rgba(255, 255, 255, 0.03);  // 背景
    // 伪元素:设置小边框
    &::before {
      position: absolute;
      top: 0;
      left: 0;
      width: 10px;
      height: 10px;
      border-left: 2px solid #02a6b5;
      border-top: 2px solid #02a6b5;
      content: '';
    }

    &::after {
      position: absolute;
      top: 0;
      right: 0;
      width: 10px;
      height: 10px;
      border-right: 2px solid #02a6b5;
      border-top: 2px solid #02a6b5;
      content: '';
    }

    .panel-footer {
      position: absolute;
      bottom: 0;
      left: 0;
      width: 100%;

      &::before {
        position: absolute;
        bottom: 0;
        left: 0;
        width: 10px;
        height: 10px;
        border-left: 2px solid #02a6b5;
        border-bottom: 2px solid #02a6b5;
        content: '';
      }

      &::after {
        position: absolute;
        bottom: 0;
        right: 0;
        width: 10px;
        height: 10px;
        border-right: 2px solid #02a6b5;
        border-bottom: 2px solid #02a6b5;
        content: '';
      }
    }

    h2 {
      height: .6rem;
      color: #fff;
      line-height: .6rem;
      text-align: center;
      font-size: 0.25rem;
      font-weight: 400;
      a {
        color: rgb(167, 167, 167);
        text-decoration: none;
        margin: 0 .125rem;
      }
      .a-active {
        color: #fff;
      }
    }

    .chart {
      height: 3rem;
    }
  }
}

(2)html文件中的head头部代码部分为: 

<!-- 页面主体部分 -->
    <section class="mainbox">
      <!-- 左侧盒子 -->
      <div class="column">
        <div class="panel bar">
          <h2>柱形图-就业行业</h2>
          <!-- 图表放置盒子 -->
          <div class="chart"></div>
          <!-- 伪元素绘制盒子下边角 -->
          <div class="panel-footer"></div>
        </div>
        <div class="panel line">
          <h2>折线图-人员变化
            <a class="a-active" href="javascript:;">2020</a>
            <a href="javascript:;">2021</a>
          </h2>
          <div class="chart"></div>
          <div class="panel-footer"></div>
        </div>
        <div class="panel pie">
          <h2>饼形图-年龄分布</h2>

          <div class="panel-footer"></div>
        </div>
      </div>
      <!-- 中间盒子 -->
      <div class="column">
        <!-- 头部 no模块 -->
        <div class="no">
          <div class="no-hd">
            <ul>
              <li>12434</li>
              <li>10983</li>
            </ul>
          </div>
          <div class="no-bd">
            <ul>
              <li>前端需求人数</li>

            </ul>
          </div>
        </div>
        <!-- map模块 -->
        <div class="map">

        </div>
      </div>
      <!-- 右侧盒子 -->
      <div class="column">
        <div class="panel bar2">
          <h2>折线图-播放量</h2>
          <div class="chart"></div>
          <div class="panel-footer"></div>

          <div class="panel-footer"></div>
        </div>
      </div>
    </section>

其中,要注意不要忘记引用js文件

<script src="js/flexible.js"></script> <script src="js/echarts.min.js"></script> <script src="js/jquery.js"></script> <script src="js/index.js"></script>

(3)浏览器显示的页面效果:

winform数据可视化控件 数据可视化界面_python_03

4、接下来需要将echarts可视化图导入到类名为“chart”的“div”标签中

其中包括几个部分:

  • 左边盒子中的三个echarts可视化图:柱状图1、折线图1、饼图1
  • 中间盒子中的地图map,包括四个部分:map1、map2、map3、地图
  • 右边盒子包含三个echarts可视化图:柱状图2、折线图2、饼图2

(1)css文件中的head头部代码部分为:

// no数字模块
.no {
  background-color: rgba(101, 132, 226, 0.1);
  padding: .1875rem;  // 边距

  .no-hd {
    position: relative;
    border: 1px solid rgba(25, 186, 139, 0.17);

    &::before {
      position: absolute;
      top: 0;
      left: 0;
      width: .375rem;
      height: .125rem;
      border-top: 2px solid #02a6b5;
      border-left: 2px solid #02a6b5;
      content: '';
    }

    &::after {
      position: absolute;
      bottom: 0;
      right: 0;
      width: .375rem;
      height: .125rem;
      border-bottom: 2px solid #02a6b5;
      border-right: 2px solid #02a6b5;
      content: '';
    }

    ul {
      display: flex;

      li {
        position: relative;
        flex: 1;  // 每一个小li各占一份
        line-height: 1rem;
        font-size: .875rem;
        color: #ffeb7b;
        text-align: center;
        font-family: electronicFont;

        &:first-child::after {
          content: '';
          position: absolute;
          top: 25%;
          right: 0;
          height: 50%;
          width: 1px;
          background-color: rgba(255, 255, 255, 0.3);
        }
      }
    }
  }

  .no-bd {
    ul {
      display: flex;

      li {
        flex: 1;    // 小例各占一份
        text-align: center;
        color: rgba(255, 255, 255, 0.7);
        font-size: .225rem;
        height: .5rem;
        line-height: .5rem;
        padding-top: .125rem;
      }
    }
  }
}

.map {
  position: relative;
  height: 10.125rem;

  .map1 {  // 球体图片模块
    width: 6.475rem;
    height: 6.475rem;
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
    background: url(../images/map.png);
    background-size: 100% 100%;  // 保证缩放
    opacity: 0.3;
  }

  .map2 {  // 旋转球体模块
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
    width: 8.0375rem;
    height: 8.0375rem;
    background: url(../images/lbx.png);
    background-size: 100% 100%;
    animation: rotate1 15s linear infinite;  // 顺时针匀速旋转,无限循环
    opacity: .6;
  }

  .map3 {
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
    width: 7.075rem;
    height: 7.075rem;
    background: url(../images/jt.png);
    background-size: 100% 100%;
    animation: rotate2 10s linear infinite;  // 逆时针匀速旋转,无限旋转
  }

  .chart {
    position: absolute;
    top: 0;
    left: 0;
    height: 10.125rem;
    width: 100%;
  }

  @keyframes rotate1 {
    from {
      transform: translate(-50%, -50%) rotate(0deg);
    }

    to {
      transform: translate(-50%, -50%) rotate(360deg);
    }
  }

  @keyframes rotate2 {
    from {
      transform: translate(-50%, -50%) rotate(360deg);
    }

    to {
      transform: translate(-50%, -50%) rotate(0deg);
    }
  }
}

/* 约束屏幕尺寸 */
@media screen and (max-width: 1024px) {
  html {
    font-size: 42px !important;
  }
}
@media screen and (min-width: 1920px) {
  html {
    font-size: 80px !important;
  }
}

(2)需要在index.js文件中编写这些echarts可视化图,

// 立即执行函数,防止变量污染 (function() {})();

// 柱状图模块1
(function () {
  // 1.实例化对象
  var myChart = echarts.init(document.querySelector(".bar .chart"));
  // 2.指定配置项和数据
  var option = {
    color: ['#2f89cf'],
    // 提示框组件
    tooltip: {
      trigger: 'axis',
      axisPointer: { // 坐标轴指示器,坐标轴触发有效
        type: 'shadow' // 默认为直线,可选为:'line' | 'shadow'
      }
    },
    // 修改图表位置大小
    grid: {
      left: '0%',
      top: '10px',
      right: '0%',
      bottom: '4%',
      containLabel: true
    },
    // x轴相关配置
    xAxis: [{
      type: 'category',
      data: ["旅游行业", "教育培训", "游戏行业", "医疗行业", "电商行业", "社交行业", "金融行业"],
      axisTick: {
        alignWithLabel: true
      },
      // 修改刻度标签,相关样式
      axisLabel: {
        color: "rgba(255,255,255,0.6)",  // 将刻度标签文字设置为白色
        fontSize: 10
      },
      // x轴样式不显示
      axisLine: {
        show: false
      }
    }],
    // y轴相关配置
    yAxis: [{
      type: 'value',
      // 修改刻度标签,相关样式
      axisLabel: {
        color: "rgba(255,255,255,0.6)",
        fontSize: 12
      },
      // y轴样式修改
      axisLine: {
        lineStyle: {
          color: "#fff",
          width: 2
        }
      },
      // y轴分割线的颜色
      splitLine: {
        lineStyle: {
          color: "rgba(255,255,255,0.1)"
        }
      }
    }],
    // 系列列表配置
    series: [{
      name: '直接访问',
      type: 'bar',
      barWidth: '35%',
      // ajax传动态数据
      data: [200, 300, 300, 900, 1500, 1200, 600],
      itemStyle: {
        // 修改柱子圆角
        barBorderRadius: 5
      }
    }]
  };
  // 3.把配置项给实例对象
  myChart.setOption(option);

  // 4.让图表随屏幕自适应
  window.addEventListener('resize', function () {
    myChart.resize();
  })
})();

// 柱状图模块2
(function () {
  // 1.实例化对象
  var myChart = echarts.init(document.querySelector(".line2 .chart"));

  // 声明颜色数组
  var myColor = ["#1089E7", "#F57474", "#56D0E3", "#F8B448", "#8B78F6"];
  // 2.指定配置项和数据
  var option = {
    grid: {
      top: "10%",
      left: '22%',
      bottom: '10%',
      // containLabel: true
    },
    xAxis: {
      // 不显示x轴相关信息
      show: false
    },
    yAxis: [{
      type: 'category',
      // y轴数据反转,与数组的顺序一致
