Example 1: Set X-Axis Limits Using xlim() Using the xlim() method, the scatterplot’s x-axis boundaries can be defined as seen in the following code: make a scatterplot with an x-axis of 10 to 40. ggplot(mtcars, aes(mpg, wt)) + geom_point() + xlim(10, 40) ...
#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 ...
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...
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 ...

Expand plot limits Conclusion Key ggplot2 R functions Start by creating a scatter plot using thecarsdata set: library(ggplot2) p <- ggplot(cars, aes(x = speed, y = dist)) + geom_point() 3 Key functions are available to set the axis limits and scales: ...

这个R tutorial描述如何使用ggplot2包修改x和y轴刻度。同样,该文包含如何执行轴转换(对数化,开方等)和日期转换。...改变x和y轴刻度下面是一些设置刻度的函数: xlim() 和 ylim() expand_limits() scale_x_continuous() 和scale_y_continuo...
