p+theme(legend.key = element_rect(fill = 'green')) 7、自定义图例标签顺序——通过将数据中的相应列数据转换为factor型数据进而调整显示顺序 df1$Samples=factor(df1$Samples,levels = c('B','A','D','C','F','G','H','I','J','E','K'))#定义顺序 ggplot(df1, aes(x = Samples, y...
ggplot(df_new,aes(y=value,x=V,lty=variable,colour=names))+geom_point()+geom_line() the output format which I prefer is something I can refer all rows of DQ0,DQ1 and DQ2 inside of each group. Any suggestions? last condition
多掌握几个图例Legend,更好地利用R语言绘图。 legend(x, y = NULL, legend, fill = NULL,col =, bty = "o",xjust = 0, yjust = 1, x.intersp = 1, y.intersp =1, adj = c(0, 0.5), text.width = NULL,xpd=TRUE) 1. Legend定位 1. 如果图例绘在制图区外,必须提前保留绘制legend的空间。
p <- ggplot(dat, aes(x, y, colour = p, size = q, shape = r)) + geom_point() p1 <- p + guides(colour = "colorbar", size = "legend", shape = "legend") p2 <- p + guides(colour = guide_colorbar(), size = guide_legend(), ...
ggplot2包中有一个用于创建grob对象的函数,参数x是一个ggplot对象: 1 ggplotGrob(x) 我们可以通过添加注释(annotate)的方式,向一个图形内部添加一个图形: + View Code 例如:向大图形中添加一个小图形: + View Code ggrepel包画图标记不重叠标签 当我们在图形中添加标签时,标签之间很容易相互重叠,包ggrepel就专...
ggplot(data=df, mapping=aes(x=Improved,y=Freq))+ geom_bar(stat="identity") 1. 2. 3. 4. 5. 绘制的条形图是相同的,如下图所示: 二,修改条形图的图形属性 条形图的图形属性包括条形图的宽度,条形图的颜色,条形图的标签,分组和修改图例的位置等。
dat<-data.frame(x=1:5,y=1:5,p=1:5,q=factor(1:5),r=factor(1:5))p<-ggplot(dat,aes(x,y,colour=p,size=q,shape=r))+geom_point()p1<-p+guides(colour="colorbar",size="legend",shape="legend")p2<-p+guides(colour=guide_colorbar(),size=guide_legend(),shape=guide_legend())p3...
