Example 1: Add Labels to Base R Scatterplot This Example illustrates how to drawlabelsto a plot created with the basic installation of the R programming language. For this, we have to use theplot()andtext()functions as shown below. Note that we have to increase the xlim of our plot to...
Add tick marks using theaxis()R function Add tick mark labels using thetext()function The argumentsrtcan be used to modify the text rotation in degrees. # Suppress the axis plot(x, y, xaxt="n", yaxt="n") # Changing x axis xtick<-seq(0, 10, by=5) axis(side=1, at=xtick, ...
plot.iris <- ggplot(iris, aes(Sepal.Length, Sepal.Width)) + geom_point() + facet_grid(. ~ Species) + stat_smooth(method = "lm") + background_grid(major = 'y', minor = "none") + # add thin horizontal lines panel_border() # and a border around each panel p2 <- add_sub(p...

barplot(values,# Add labels to barplotnames.arg=group) Figure 4: Barchart with Labels of Bars. Note that the vector containing our labels needs to have the same length and ordering as the vector containing our values. Example 5: Stacked Barplot with Legend ...
p2<-add_sub(plot.iris,"Annotation underneath a faceted plot, left justified.",x=0,hjust=0)ggdraw(p2) 最后,我们也可以将注释移动至图形内部。注意坐标x是相对于图形板左边边界的度量,而y是相对于已经添加到图形下方的空间(有点疑惑,需要尝试才知道),它们不是以绘制的数据度量的。这保证了多个数据不同的...
连续变量使用scale_*_continuous()函数，参数breaks设置各个刻度的位置，参数labels设置各个刻度对应的标签。
ggplot作图插件:ggThemeAssist,加载后可在左上角Addins(插件中可找到)"ggplot Theme Assistant",将画图代码设置成一个object,选中object然后点击插件中的功能即可;或者直接调用函数ggThemeAssistGadget(plot_name). 参考ggplot2作图不用敲代码 / ggplot2的辅助工具:ggThemeAssist与eoffice ...
To add a text to a plot in R, the text() and mtext() R functions can be used. Add texts within the graph The text() function can be used to draw text inside the plotting area. A simplified format of the function is : text(x, y, labels) x and y: numeric vectors specifying th...
which:类型,可选"plot"、"figure"、"inner"、"outer" lty:线形 ...:还支持其他参数,如col,bty,lwd等等 axis()函数 功能: 将轴添加到当前绘图,允许指定边,位置,标签和其他选项。 用法: axis(side,at=NULL,labels=TRUE,tick=TRUE,line=NA, pos=NA,outer=FALSE,font=NA,lty=“solid”, ...
