Add a title, subtitle, caption and change axis labels: bxp <- bxp + labs(title = "Effect of Vitamin C on Tooth Growth", subtitle = "Plot of length by dose", caption = "Data source: ToothGrowth", x = "Dose (mg)", y = "Teeth length", tag = "A") bxp ...
axis.text.y=element_text(size=10)) # Y axis text 四 图例设置 legend 可以使用guide函数或者scale函数进行修改,这里分别进行一下介绍。 4.1 根据guide修改 p3 <- p2 + guides(color=guide_legend(title = "shape change Legend")) p3 注意这里使用color=guide_legend ,和aes对应 。
font("legend.title", color = "blue", face = "bold")+ font("legend.text", color = "red") legend参数是指定图例位置的字符型向量,可选值包括c(“top”, “bottom”, “left”, “right”, “none”)。如果不想显示图例,可以设置legend = “none”。图例的位置也可由坐标位置来c(x, y)指定。
p2 <- p1 + labs(x="X轴",y = "这是Y轴",title = "生信补给站")p2 3.2 设置坐标大小,颜色 根据实际情况设置大小,颜色和倾斜角度可以更清晰的展示结果 p2 + theme(axis.title.x=element_text(vjust=1,size=20), # X axis titleaxis.title.y=element_text(size=10,color = "blue"), # Y axis...
