, ggplot2 can frequently be used to set the axis bounds on a plot. The following functions make it simple to accomplish this: xlim(): defines the x-axis’s lowest and upper limits. ylim(): defines the y-axis’s lower and upper limits....
#setthe interceptofx and y axisat(0,0)sp+expand_limits(x=0,y=0)# change the axis limits sp+expand_limits(x=c(0,30),y=c(0,150)) 使用scale_xx()函数 也可以使用函数scale_x_continuous()和scale_y_continuous()分别改变x和y轴的刻度范围。t 函数简单的形式如下: 代码语言:javascript 复制 ...
sec.axis = waiver() ) 连续标度函数与离散标度函数有一些共同参数,此外还有如下特有参数: minor_breaks:次级刻度的位置; n.breaks:breaks参数的替代参数,指定坐标轴刻度的数目。 p31 <- ggplot(mtcars, aes(mpg, drat)) + geom_point() p32 <- p31 + scale_x_continuous(limits = c(15, 30), breaks ...
2.将x轴标签加粗,字体颜色变红,大小为12号,角度与x轴成45度(y轴标签类似) p + theme(axis.text.x = element_text(face = "bold", color = "red", size = 12, angle = 45), axis.text.y = element_text(face = "bold", color = "blue", size = 12, angle = 45)) 3.删除x,y轴标签...
# Make sure to include 0 in the y axis bp + expand_limits(y=0) # y轴从0開始 1. 2. # 设置y轴的范围 bp + expand_limits(y=c(0,8)) 1. 2. 我们能够通过expand_limits设置坐标轴的范围, 可是假设 scale_y_continuous 被使用, 那么就会覆盖ylim...
Expand plot limits Key function expand_limits(). Can be used to : quickly set the intercept of x and y axes at (0,0) expand the limits of x and y axes # set the intercept of x and y axis at (0,0) p + expand_limits(x = 0, y = 0) # change the axis limits p + expand...
调整参数limits可以设定x轴范围 scale_y_continuous(limits=c(0, 10)) # 设定范围0-10,x轴同理 注意:ggplot2包有两种设置值域的方式,第一种是修改标度...从本质上讲,只是将数据放大或缩小到指定的范围。...()中调整参数breaks,从而将刻度间距设为相同。...使用seq()函数可以生成刻度线的位置向量,如seq...
* sec.axis 表示是否开启次坐标轴 例: library(ggplot2) p1 <- ggplot(mpg, aes(displ, hwy)) + geom_point() p1 p1 + scale_x_continuous(name = "发动机排量/L", limits = c(2,6), breaks = c(2, 4, 6), labels = c("two", "four", "six"), minor_breaks = c(3, 5)) + # ...
# Set the y-axis limits ylim(-2,2) use ase(x,0) to set y=0 and set limits to the y-axis Typically, alpha blending (i.e. adding transparency) is recommended when using solid shapes. Alternatively, you can use opaque, hollow shapes. ...
ggplot图的元素可以主要可以概括如下:最大的是plot(指整张图,包括background和title),其次是axis(包括stick,text,title和stick)、legend(包括backgroud、text、title)、facet这是第二层次,其中facet可以分为外部strip部分(包括backgroud和text)和内部panel部分(包括backgroud、boder和网格线grid,其中粗的叫grid.major,细...
