Javascript JS-如何在Google图形（SlangedText）上旋转标签（hAxis）？,javascript,html,graph,google-visualization,axis,Javascript,Html,Graph,Google Visualization,Axis,很长时间以来，我一直试图在下图中简单地旋转hAxis。尝试了下面解释的几种解决方案！真不敢相信这么简单的事情看起来那么难做。源代码如下： <html> <title>VM Allocation Performance</title> <meta http-equiv="refresh" content="30"> <head> <script type="text/javascript" sr

以下是我迄今为止所做的尝试：

我阅读了谷歌文档，相应地修改了代码（因为它是一个“材料”图等等），但仍然一无所获

我试着用我发现的相同的hAxis块，没有运气

我更深入地了解了一些细节，发现选项“slidedtext”只能在离散轴上工作，所以我认为我必须将hAxis类型从Date/Time更改为String，我尝试了，但没有成功

我继续使用SO的解决方案，虽然我仍然可以渲染图形，但我的日期/时间标签仍然没有完全显示出来（这就是为什么我要旋转它们）

有人能帮忙吗？

换成柱形图而不是条形图。看

它很管用，非常好。只是一个注释，这样做意味着我使用的是经典图表，而不是材质图表。在多次尝试后，我无法在列材质图表上使用SlidedText，文档中也未提及：/（）@Aurax22是的，SlidedText是材质图表尚不可用的选项之一。
