Javascript 在仪表板上刷新google可视化多个图表

我在仪表板上使用了多个图表。我的图表运行正常，没问题。我需要的是刷新图表并获得更新的结果

这是我的饼图和条形图脚本

在新页面中分离我的图表代码，并在用户单击“刷新”按钮时重新加载页面。
重新加载特定图表@whitehat建议将php和html/javascript分离为单独的文件，请参阅--使用类似的方法可以轻松地用新数据重新加载单个图表--但是当像在origina中一样混合在一起时l post，几乎唯一的选择是重新加载页面…请阅读-总结是，这不是向志愿者致辞的理想方式，可能会对获得答案产生反作用。请不要将此添加到您的问题中。您想显示实时数据还是仅仅刷新？
