(3) 改变坐标轴名称的字体大小 myplot + theme(axis.title = element_text(size = 30)) 改变坐标轴名称的字体大小 类似的,如果需要只改变某个坐标轴名称的字体大小,也可以用: myplot + theme(axis.title.x = element_text(size = 30)) myplot + theme(axis.title.y = element_text(size = 30)) 只改...
aes(x = A, y = B)) + geom_point() p = p + xlab("A long x-string so we can see the effect of the font switch") p = p + ylab("Likewise up the ordinate") p+labs(title="datadagtat sdfas",x="X axis",y="Y axis")+theme(plot.title = element_text(hjust = 0.5...
另外,上面直接使用title设置,它会改变包括图表标题,x轴,y轴以及图例的文本样式。如果只是更改某个样式,可以使用单独设置。比如 1 2 3 4 5 6 p+labs(x="人口",y="失业率",title="经济调查报告")+ theme(title=element_text(family="myFont",size=12,color="red", face="italic",hjust=0.2,lineheight=...

You will learn how to add and change a ggplot main title, subtitle and caption, as well as, how to change the title position font size and color.
