R 如何在ggplot2中调整X轴标签位置

我一直在努力定制ggplot2生成图形的标签。最初，轴心是HabFac，它只有三层。然而，我需要x轴按HabFac进行分组，但它的标签是其他的

因此，我将x轴的极限增加到7

使用“缩放x离散”链接新的限制和标签

但这不起作用。。。 看起来标签和盒子的比例不同。我试图指定

中断

，但没有帮助

非常感谢您的帮助

编辑 下面是一些简化的数据

当x轴是一个

因子时，标签是
a
b
c
还是
1
2
3
并不重要。无论哪种方式，刻度都是离散的，因此指定
1.25
没有意义，就像
a.43
没有意义一样。您需要一个因子来表示分组（可能是
HabFac
）和另一个因子来表示各个级别。然后，您可以基于
HabFac
使用
fill
颜色，或者使用
facet\u wrap
与
HabFac
一起使用
aes（x=
单个因子水平。@shujaa感谢您的回复。我认为应该有一种方法可以直接修改这些x标签的位置。就像我可以使用
ggplot_gtable（p_TT）$data[[1]]更改框的位置一样$x
如果您只想更改
HabFac
每一级别的标签，通常的方法就是重命名
HabFac
的级别。您的意思是将
HabFac
的级别从3增加到7，然后重命名它们吗？您能更具体一点吗？谢谢！我不知道
HabFac
的级别或标签是什么>是的，所以我不能具体说明。给出一些带有
dput
的示例数据和所需的输出，然后我们可以讨论细节。
