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

data_occ.addColumn('string', 'Step');
data_occ.addColumn('number', 'Number');
data_occ.addRows([

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:
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:
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);
}
