javascript - Google charts into JQuery Tab draw问题

Question

我目前正在尝试移动 Google 图表，其中数据是通过 socket.io 从服务器端提取的，并将它们绘制到 JQuery UI 选项卡中。

我遇到的问题是，绘制的第一份报告工作正常，看起来也不错。

第二个看起来很不对，我认为这可能与我如何绘制表格有关但我无法找到解决方案，当我只是将它绘制到 JQuery UI 选项卡之外的 div 中时不会发生此问题。

这是我现在拥有的当前代码:

jQuery(function ($) {
    var socket = io.connect();
    var result = [];
    google.charts.load('current', {
            packages : ['bar']
        });

 $(function() {
    $( "#tabs" ).tabs();
  });

    socket.on("SQLdipo", function (valueArr) {
        google.charts.setOnLoadCallback(drawMaterial);
        var data = valueArr;
        function drawMaterial() {

            var result = [['Call Disposition', 'Answered', 'No Answer', 'Busy','Failed']].concat(valueArr);
            var options = {
                height: 350,
                 chart: {
            title: 'Agent Call Dispositions',
            subtitle: 'Agent call states',
          }
            };
            var chartdata = new google.visualization.arrayToDataTable(result);
            var chart1 = new google.charts.Bar(document.getElementById('chartDipo'));
            chart1.draw(chartdata, options);
        }
    });

    socket.on("SQLmins", function (valueArr) {
        google.charts.setOnLoadCallback(drawChart);
        var data = valueArr;
        function drawChart() {

            var result = [['Total Mins', 'Active','Inactive']].concat(valueArr);
            var options = {
                height: 350,
                 chart: {
            title: 'Agent Activity in seconds',
            subtitle: 'Agent Duration Activity',
          }
            };
            var chartdata = new google.visualization.arrayToDataTable(result);
            var chart2 = new google.charts.Bar(document.getElementById('chartMins'));
            chart2.draw(chartdata, options);
        }
    });
});

我已经配置了一个 JS fiddle 来模拟我遇到的问题 HERE

问题是图表在最初绘制时是隐藏的。
您可以设置特定的尺寸选项或...

等到选项卡被激活，然后第一次绘制图表，如本例所示...

$(document).ready(function() {
  $("#tabs").tabs({
    activate: function(event, ui){
      switch (ui.newTab.index()) {
        case 0:
          drawMaterial();
          break;

        case 1:
          drawChart();
          break;
      }
    }
  });

  google.charts.load('current', {
    callback: drawMaterial,
    packages: ['bar']
  });

  function drawMaterial() {
    var data = google.visualization.arrayToDataTable([
      ['Call Disposition', 'Answered', 'No Answer', 'Busy', 'Failed'],
      ['1000', 4, 0, 2, 0],
      ['1001', 4, 2, 0, 0],
      ['1002', 6, 0, 0, 0]
    ]);

    var options = {
      height: 350,
      chart: {
        title: 'Agent Call Dispositions',
        subtitle: 'Agent call states',
      }
    };
    var chart1 = new google.charts.Bar(document.getElementById('chartDipo'));
    chart1.draw(data, options);
  }

  function drawChart() {
    var data = google.visualization.arrayToDataTable([
      ['Call Disposition', 'Answered', 'No Answer', 'Busy', 'Failed'],
      ['1000', 4, 0, 2, 0],
      ['1001', 4, 2, 0, 0],
      ['1002', 6, 0, 0, 0]
    ]);

    var options = {
      height: 350,
      chart: {
        title: 'Agent Call Dispositions',
        subtitle: 'Agent call states',
      }
    };
    var chart1 = new google.charts.Bar(document.getElementById('chartMins'));
    chart1.draw(data, options);
  }
});
