多个Google图表无法在同一页面上正常显示

我在一个页面上显示了4个图表。当单独绘制时它们完美地工作,但是当我尝试超过1时它们并不全部显示。我还注意到,在调整窗口大小(因此刷新图表)时,"活动"图表可以改变。

这是我绘制图表的方法:

function drawChart() {
    // Occurrences per step
    var data_occ =  new google.visualization.DataTable();
    data_occ.addColumn('string', 'Step');
    data_occ.addColumn('number', 'Number');
    data_occ.addRows([
        ['NO_STOP_DEP', 2057],
        ['FIND_STOPS_DEP', 795],
        ['FIND_STOPS_ARR', 423],

        }
    };
    var chart_occ = new google.charts.Bar(document.getElementById('chart_occ'));
    chart_occ.draw(data_occ, opt_occ);

我还将代码上传到a jsfiddle,以便您自己查看。您可以使用顶部的整数来选择要显示的图形。如果值不是2的幂(即显示多个图形),则会导致以下结果:

  • div的大小,我的意思是布局表明它存在
  • div中将不会绘制任何内容

这里有一个示例,其中绘制了两个图形,一个是正确绘制的,第二个是空白的:

example with one graph not working

我们可以清楚地看到平均持续时间 div有一个大小,但是空白。

答案 0 :(得分:5)

the known issue存储库中报告的google-visualization-issues

  

人们看到的多个实例的大小问题   应使用此新版本解决材料图表。您可以   更改您的代码现在加载“1.1”,以便在候选人发布时   变得可用,你将使用它。

目前至少有两种解决方案可用。

选项1.使用冻结的版本加载程序。

自v43候选版本推出以解决此问题 切换到使用冻结版本加载器。

步骤:

1)添加对loader的引用:<script src="http://www.gstatic.com/charts/loader.js"></script>

2)然后加载43版本的库:google.charts.load("43", { packages: ["corechart", "gauge", "table", "timeline", "bar"] });

3)将google.setOnLoadCallback(drawChart);替换为google.charts.setOnLoadCallback(drawChart);

选项2.同步渲染图表

由于draw函数是异步,我们利用ready事件处理程序按顺序绘制图表,在这种情况下,应该正确呈现多个图表,如下所示。

function drawChart(chartsQueue,index) {
    index = index || 0;
    if (index === chartsQueue.length)
        return;



    var chart = new google.charts.Bar(document.getElementById(chartsQueue[index].id));
    google.visualization.events.addOneTimeListener(chart, 'ready', function() {
        drawChart(chartsQueue, index + 1); //draw next chart
    });
    chart.draw(chartsQueue[index].data, chartsQueue[index].options);
}
