Question

我有一个气泡图，里面有一些饼图。现在，我正专注于将饼图与各自的div对齐。饼图应该与div的左上角对齐，但是它们与中心对齐而不对我的top: 0px right: 0px attributes做出反应。这是我的jsFiddle：

HTML / CSS

<div id="chart_div"></div>

.whiteHat {
  border: none;
  width: 100px;
  position: absolute;
  background-color: red;
}

JS

google.charts.load('current', {
  'packages': ['corechart']
});
google.charts.setOnLoadCallback(drawSeriesChart);

function drawSeriesChart() {

  var data = google.visualization.arrayToDataTable([
    ['ID', 'Life Expectancy', 'Fertility Rate', 'Region', 'Population'],
    ['CAN', 80.66, 1.67, 'North America', 33739900],
    ['DEU', 79.84, 1.36, 'Europe', 81902307],
    ['DNK', 78.6, 1.84, 'Europe', 5523095],
    ['EGY', 72.73, 2.78, 'Middle East', 79716203],
    ['GBR', 80.05, 2, 'Europe', 61801570],
    ['IRN', 72.49, 1.7, 'Middle East', 73137148],
    ['IRQ', 68.09, 4.77, 'Middle East', 31090763],
    ['ISR', 81.55, 2.96, 'Middle East', 7485600],
    ['RUS', 68.6, 1.54, 'Europe', 141850000],
    ['USA', 78.09, 2.05, 'North America', 307007000]
  ]);

  var options = {
    title: 'Correlation between life expectancy, fertility rate ' +
      'and population of some world countries (2010)',
    hAxis: {
      title: 'Life Expectancy'
    },
    vAxis: {
      title: 'Fertility Rate'
    },
    bubble: {
      textStyle: {
        fontSize: 11
      }
    }
  };
  var container = document.getElementById('chart_div');
  var chart = new google.visualization.BubbleChart(document.getElementById('chart_div'));
  google.visualization.events.addListener(chart, 'ready', function() {
    var layout = chart.getChartLayoutInterface();
    for (var i = 0; i < data.getNumberOfRows(); i++) {
      // add image above every fifth element
      if (i % 5 == 0) {
        var xPos = layout.getXLocation(data.getValue(i, 1));
        var yPos = layout.getYLocation(data.getValue(i, 2));

        var data2 = google.visualization.arrayToDataTable([
          ['Task', 'Hours per Day'],
          ['Work', 11],
          ['Eat', 2],
          ['Commute', 2],
          ['Watch TV', 2],
          ['Sleep', 7]
        ]);
        var pie = document.getElementById('piechart');
        var whiteHat = container.appendChild(document.createElement('div'));
        whiteHat.className = 'whiteHat';
        whiteHat.style.top = yPos + 'px';
        whiteHat.style.left = xPos + 'px';
        new google.visualization.PieChart(whiteHat).draw(data2, {
          legend: {
            position: 'none'
          },
          backgroundColor: 'transparent',
          chartArea: {
            top: 0,
            left: 0,
            width: "100%",
            height: "100%"
          },
        });
      }
    }
  });
  chart.draw(data, options);
}

我只是想将饼图对齐div的左上角，我使用红色背景来显示div。我该如何解决这个问题？

我刚刚添加了这个CSS，使它看起来不错：

.whiteHat {
  left: 0 !important;
  bottom: 0 !important;
  width: 50% !important;
  height: auto !important;
  right: auto !important;
  top: auto !important;
}
.whiteHat + .whiteHat {
  left: auto !important;
  bottom: 0 !important;
  width: 50% !important;
  height: auto !important;
  right: 0 !important;
  top: auto !important;
}

我使用!important的主要原因是使用内联样式覆盖插件生成的样式。

<强>糟糕即可。左上角是吗？只需交换值。

.whiteHat {
  left: 0 !important;
  bottom: auto !important;
  width: 50% !important;
  height: auto !important;
  right: auto !important;
  top: 0 !important;
}
.whiteHat + .whiteHat {
  left: auto !important;
  bottom: auto !important;
  width: 50% !important;
  height: auto !important;
  right: 0 !important;
  top: 0 !important;
}
