value: 100 }, { date: "2019-03-01", value: 1 } ] 当我使用D3's Area Chart Example时,他们将X轴设置为: const x = d3.scaleTime() .domain(d3.extent(data, d => Date.parse(d.date))) .range([margin.left, w
在ggplot中,可以使用scale_x_continuous函数来设置x轴刻度线的最大数量。该函数可以接受参数breaks来指定刻度线的位置,以及labels来指定刻度线的标签。 以下是一个示例代码,演示如何使用ggplot设置x轴刻度线的最大数量为5: 代码语言:R 复制 library(ggplot2) # 创建一个示例数据集 data <- data.frame( x = c(...
p4 <- p+scale_y_continuous(labels = label_comma()) p2+p3+p4 plot of chunk unnamed-chunk-11 如果想要修改颜色、方向、粗细等,就要使用theme()函数修改。 p1 <- p+theme(axis.text.x = element_text(color ="red",size =14,angle =45, hjust =1,vjust =1 ), axis.text.y = element_text(...
panel.grid.major = element_blank(), panel.grid.minor = element_blank(), axis.line = element_line(colour = “gray”), plot.title = element_text(hjust = 0.5), plot.subtitle = element_text(hjust

在qplot()中可以选择二维分面(比如x~y)使用facet_grid,一维分面(比如~x)使用facet_warp,分面会占用大量空间,所以本节使用mpg数据集的子集来展示,它有几个简单的水平:三种气缸(4, 6, 8)和两种驱动轮(4,f)。子集提出了原数据集的29辆汽车。 mpg2 = subset(mpg, cyl != 5 & drv %in% c("4", "f...

Eachgeom_rectobject would occupy exactly one of the x axis segments. That is, the firstgeom_rectobject would span (on the x axis) the interval 0 to 10, the second would span 10 to 20. So far, I've tried to use the ggplot2 functionscale_x_continuouswith a custom ...
