控制 ggplot 山脊线图中的 X 轴值

问题描述

我在脊线密度图中叠加了密度图（男孩与女孩）。 X 轴值是从 1 到 9 的整数，但在密度图中，它们被平滑为从 0 到 10。此外，X 轴显示十进制值，例如 2.5 和 7.5。

1. 有没有办法确保只显示整数值而不显示小数值？
2. 我是否可以控制显示范围仅从 1 到 9 而没有 0 和 10 部分：换句话说，只显示值 1 和 9 之间的图形部分？

以下是一些示例数据：

rank<-c(1,2,3,1,5,7,4,6,8,9,3)
gender<-c("M","M","F","F")
time<-c(1,3)
data<-data.frame(rank,gender,time)

这是我使用的代码：

ggplot(math_dat,aes(x = rank,y = time,color = gender,point_color = gender,fill = gender)) +
  geom_density_ridges(
    jittered_points = TRUE,scale = .95,rel_min_height = .01,point_shape = "|",point_size = 3,size = 0.25,position = position_points_jitter(height = 0)
  ) +
  scale_y_discrete(expand = c(0,0)) +
  scale_x_continuous(expand = c(0,0),name = "Rankings") +
  scale_fill_manual(values = c("#33FFDE50","#00663350"),labels = c("Girls","Boys")) +
  scale_color_manual(values = c("#33FFDE","#006633"),guide = "none") +
  scale_discrete_manual("point_color",values = c("#33FFDE",guide = "none") +
  coord_cartesian(clip = "off") +
  guides(fill = guide_legend(
    override.aes = list(
      fill = c("#33FFDEA0","#006633A0"),color = NA,point_color = NA)
  )
  ) +
  ggtitle("Ranks over time") +
  theme_ridges(center = TRUE)

这是我的情节：

谢谢！

解决方法

尝试明确给出休息时间：

ggplot(data,aes(x = rank,y = time,color = gender,point_color = gender,fill = gender)) +
  geom_density_ridges(
    jittered_points = TRUE,scale = .95,rel_min_height = .01,point_shape = "|",point_size = 3,size = 0.25,position = position_points_jitter(height = 0)
    ) +
  scale_y_discrete(expand = c(0,0)) +
  scale_x_continuous(expand = c(0,0),name = "Rankings",breaks = seq(0,10,by = 2)) + #give the break values here
  scale_fill_manual(values = c("#33FFDE50","#00663350"),labels = c("Girls","Boys")) +
  scale_color_manual(values = c("#33FFDE","#006633"),guide = "none") +
  scale_discrete_manual("point_color",values = c("#33FFDE",guide = "none") +
  coord_cartesian(clip = "off") +
  guides(fill = guide_legend(
    override.aes = list(
      fill = c("#33FFDEA0","#006633A0"),color = NA,point_color = NA)
  )
  ) +
  ggtitle("Ranks over time") +
  theme_ridges(center = TRUE)
