Define Segments in y-Axis for 'ggplot2'

Description

Easy-to-define segments in y-axis for 'ggplot2'.

Usage

gggap(plot, ylim, segments, tick_width, rel_heights, vjust = 0,margin = c(top = 1, right = 2, bottom = 1, left = 1), ...)

Arguments

`plot`	A 'ggplot2' plot.
`ylim`	The y-axis limits.
`segments`	The interval of a segment. If more than one intervals are given, please use list() to concatenate them.
`tick_width`	One or more numbers for each segmented y-axis.
`rel_heights`	Numerical vector of relative segmented y-axis and segments heights, default is 1 and 0.
`vjust`	Vertical justification. Default = 0 (baseline at y).
`margin`	Margins around the text.
`...`	Arguments will be handed to plot_grid() in 'cowplot'.

简单版使用代码

data(mtcars)
library(ggplot2)
p <- ggplot(data = mtcars, aes(x = gear, fill = gear)) +geom_bar() +ggtitle("Number of Cars by Gears") +xlab("Gears")# single segments and missing tick_width
gggap(plot = p,segments = c(5, 10),ylim = c(0, 50)
)

复杂版使用代码

gggap(plot = p,segments = list(c(2.5, 4), c(5, 10)),  #设置两个阶段 c(2.5, 4), c(5, 10)tick_width = c(1, 0.5, 10),            #设置不同部分的坐标间隔rel_heights = c(0.2, 0, 0.2, 0, 1),    #相对分段y轴和分段高度的数值向量，默认值为1和0ylim = c(0, 50)
)
