我正在尝试使用 R Studio 进行数据可视化，需要 X 轴和 Y 轴上的所有点

Question

sample image pic

我是 R 编程的新手，正在尝试使用 ggplot2 进行简单的数据可视化。我正在尝试在 X 轴上显示 Airbnb 酒店的夜间价格分布。 'Price' 在 X 轴上，我试图在该列中显示所有价格（而不仅仅是 0,100,200,300），例如 0,10,20,30，.....有人可以帮忙吗。

Answer 1

看看 tidyverse R 包，尤其是 dplyr 和 ggplot2：

library(tidyverse)

# create example data
set.seed(1337)
prices <- tibble(
  id = seq(100),
  price = rnorm(mean = 100, sd = 50, 100) %>% abs()
)


filtered_prices <- filter(prices, price < 100)
qplot(price, data = filtered_prices, geom = "histogram")
#> `stat_bin()` using `bins = 30`. Pick better value with `binwidth`.

qplot(price, data = filtered_prices, geom = "density")

^{由 reprex package (v2.0.1)}

Answer 2

使用ggplot2，可以使用geom_density，然后显示x-axis沿线的每个10，可以使用scale_x_continuous.

library(ggplot2)

ggplot(df, aes(x=price)) +
  geom_density(alpha=0.4) +
  scale_x_continuous(breaks = seq(0, max(df$price), 10))

输出

数据（感谢@danlooo 提供数据）
