Change the style and the orientation angle of axis tick labels. For a vertical rotation of x axis labels useangle = 90. # Rotate x and y axis text by 45 degree# face can be "plain", "italic", "bold" or "bold.italic"p + theme(axis.text.x = element_text(face ="bold", color ...

同样,因为我们想要修改主题的属性,所以我们使用theme()函数,axis.title 和 axis.text来修改字体和边距。以下所有主题元素的修改不仅适用于标题plot.title,还适用于所有其他标签,如plot.subtitle, plot.caption, plot.caption, legend.title, legend.text, axis.title和axis.text。 ggplot(chic, aes(x = date, y ...

ggplot(df1, aes( x = bigregion, y = ratio)) + geom_col() + labs(y = "Ratio") 当x轴的分组较多时,区分各组的文字标签可能会重叠。为此,可以将文字标签旋转45度角: ggplot(df1, aes( x = bigregion, y = ratio)) + geom_col() + labs(y = "Ratio") + theme( axis.text.x = elemen...

将数据输入到ggplot()函数中, 并指定参与作图的每个变量分别映射到哪些图形特性, 比如映射为x坐标、y坐标、颜色、形状等。 这些映射称为aesthetic mappings或aesthetics。 选择一个合适的图形类型, 函数名以geom_开头, 如geom_point()表示散点图。 图形类型简称为geom。 将ggplot()部分与geom_xxx()部分用加号连接...
