今天小编给大家推荐一种绘制另类分布图的绘制方法,其可以绘制出经济学人风格的箱线分布统计图。当然,你可以将其看作是箱线图的另外一种可视化形式。涉及的知识点为R-ggeconodist包绘图技巧,详细内容如下:
R-ggeconodist包简介
R-ggeconodist包样例介绍
R-ggeconodist包作为建立在ggplot2基础上的第三方包,其可以任意添加其他图层(geom_),当然,其目的是帮助我们绘制出经济学人风格样式的箱线统计图,主要包含的绘图函数如下:
add_econodist_legend():获取经济学人风格的图例(econodist legend )
econodist_legend_grob():创建与Econodist图表一起使用的图grob。
geom_econodist():经济学人图层绘制。
left_align():帮助将ggplot2绘图组件左侧。
theme_econodist():经济学人风格的ggplot2绘图主题。
接下来,小编就通过几个例子介绍R-ggeconodist包的绘图效果。
「样例一」:ggplot2::geom_boxplot() 和 ggeconodist::geom_econodist()
ggplot2::geom_boxplot()
- library(tidyverse)
- library(ggtext)
- library(hrbrthemes)
- library(wesanderson)
- library(ggsci)
- library(ggeconodist)
-
- plot01 <- ggplot(mpg, aes(class, hwy)) +
- geom_boxplot() +
- labs(
- title = "Example of <span style='color:#D20F26'>ggplot2::geom_boxplot function</span>",
- subtitle = "processed charts with <span style='color:#1A73E8'>geom_boxplot()</span>",
- caption = "Visualization by <span style='color:#0057FF'>DataCharm</span>") +
- hrbrthemes::theme_ipsum(base_family = "Roboto Condensed") +
- theme(
- plot.title = element_markdown(hjust = 0.5,vjust = .5,color = "black",
- size = 20, margin = margin(t = 1, b = 12)),
- plot.subtitle = element_markdown(hjust = 0,vjust = .5,size=15),
- plot.caption = element_markdown(face = 'bold',size = 12)
- )
ggeconodist::geom_econodist()
- plot01_01 <- ggplot(mpg, aes(class, hwy)) +
- ggeconodist::geom_econodist(width = 0.25) +
- labs(
- title = "Example of <span style='color:#D20F26'>ggeconodist::geom_econodist function</span>",
- subtitle = "processed charts with <span style='color:#1A73E8'>geom_econodist()</span>",
- caption = "Visualization by <span style='color:#0057FF'>DataCharm</span>") +
- hrbrthemes::theme_ipsum(base_family = "Roboto Condensed") +
- theme(
- plot.title = element_markdown(hjust = 0.5,vjust = .5,color = "black",
- size = 20, margin = margin(t = 1, b = 12)),
- plot.subtitle = element_markdown(hjust = 0,vjust = .5,size=15),
- plot.caption = element_markdown(face = 'bold',size = 12)
- )
下面这幅图可以更好的对比两者不同的可视化效果:
介绍完具体的不同之后,我们再试着对其默认的颜色进行更改:
「样例二」:
- plot02 <- ggplot(mpg, aes(class, hwy)) +
- ggeconodist::geom_econodist(width = 0.5,median_point_size = 1.5,tenth_col = "#BC3C28", ninetieth_col = "#0072B5") +
- coord_flip() +
- labs(
- title = "Example of <span style='color:#D20F26'>ggeconodist::geom_econodist function</span>",
- subtitle = "processed charts with <span style='color:#1A73E8'>geom_econodist()</span>",
- caption = "Visualization by <span style='color:#0057FF'>DataCharm</span>") +
- hrbrthemes::theme_ipsum(base_family = "Roboto Condensed") +
- theme(
- plot.title = element_markdown(hjust = 0.5,vjust = .5,color = "black",
- size = 20, margin = margin(t = 1, b = 12)),
- plot.subtitle = element_markdown(hjust = 0,vjust = .5,size=15),
- plot.caption = element_markdown(face = 'bold',size = 12)
- )
当然,你还可以附上不同颜色:
「样例三」:
- plot03 <- ggplot(mpg, aes(class, hwy)) +
- ggeconodist::geom_econodist(aes(fill=factor(drv)),alpha=.5) +
- ggsci::scale_fill_nejm()+
- labs(
- title = "Example of <span style='color:#D20F26'>ggeconodist::geom_econodist function</span>",
- subtitle = "processed charts with <span style='color:#1A73E8'>geom_econodist()</span>",
- caption = "Visualization by <span style='color:#0057FF'>DataCharm</span>") +
- hrbrthemes::theme_ipsum(base_family = "Roboto Condensed") +
- theme(
- plot.title = element_markdown(hjust = 0.5,vjust = .5,color = "black",
- size = 20, margin = margin(t = 1, b = 12)),
- plot.subtitle = element_markdown(hjust = 0,vjust = .5,size=15),
- plot.caption = element_markdown(face = 'bold',size = 12)
- )
「样例四」:添加额外样例
- gapminder %>%
- filter(year %in% c(1952, 1962, 1972, 1982, 1992, 2002)) %>%
- filter(continent != "Oceania") %>%
- ggplot(aes(x = factor(year), y = lifeExp, fill = continent)) +
- geom_econodist(
- median_point_size = 1.2,
- tenth_col = "#b07aa1",
- ninetieth_col = "#591a4f",
- alpha = .5,
- show.legend = FALSE
- ) +
- ggsci::scale_fill_jama(name = NULL) +
- coord_flip() +
- facet_wrap(~continent, nrow = 4) +
- labs(
- title = "Example of <span style='color:#D20F26'>ggeconodist::geom_econodist function</span>",
- subtitle = "processed charts with <span style='color:#1A73E8'>geom_econodist()</span>",
- caption = "Visualization by <span style='color:#0057FF'>DataCharm</span>") +
- hrbrthemes::theme_ipsum_rc(base_family = "Roboto Condensed") +
- theme(
- plot.title = element_markdown(hjust = 0.5,vjust = .5,color = "black",
- size = 20, margin = margin(t = 1, b = 12)),
- plot.subtitle = element_markdown(hjust = 0,vjust = .5,size=15),
- plot.caption = element_markdown(face = 'bold',size = 12)
- ) %>%
- # 添加额外图例
- add_econodist_legend(
- econodist_legend_grob(
- tenth_col = "#b07aa1",
- ninetieth_col = "#591a4f",
- ),
- below = "axis-b-1-4",
- just = "right"
- ) %>%
- grid.draw() %>%
- ggsave(filename = geom_econodist04.png",
- width = 7.5, height = 8, dpi = 900)
