[英]how to automatically align the axis limits for different ggplots
我正在運行回歸並使用 ggplots 呈現結果。 通常,目的是查看在第 2 階段發生的政策的動態效果。
我正在繪制回歸結果,我從回歸函數創建的數據框看起來像
dfplot1 <- data.frame(coef=c(0.05,0,0.1,0.15,0.2),
se=c(0.1,0,0.1,0.1,0.1),
period=1:5)
dfplot2 <- data.frame(coef=c(0.05,0,0.12,0.18,0.24),
se=c(0.12,0,0.12,0.12,0.12),
period=1:5)
我使用標准誤差繪制系數
library(ggplot2)
library(patchwork)
p1 <- ggplot(dfplot1)+
geom_point(aes(x=period, y=coef))+
geom_segment(aes(x=period, xend=period, y=coef-1.96*se, yend=coef+1.96*se))+
geom_segment(aes(x=period, xend=period, y=coef-1.96*se, yend=coef+1.96*se))+
labs(x='Year', y='Coefficients')+
geom_hline(yintercept = 0, linetype = "dashed")+
theme(panel.background = element_blank())
p2 <- ggplot(dfplot2)+
geom_point(aes(x=period, y=coef))+
geom_segment(aes(x=period, xend=period, y=coef-1.96*se, yend=coef+1.96*se))+
geom_segment(aes(x=period, xend=period, y=coef-1.96*se, yend=coef+1.96*se))+
labs(x='Year', y='Coefficients')+
geom_hline(yintercept = 0, linetype = "dashed")+
theme(panel.background = element_blank())
p1|p2
我可以在每個 ggplot 中使用 ylim 來設置 y 軸限制並使它們相同
p1+ylim(-0.5,0.5)
p2+ylim(-0.5,0.5)
為了更好地可視化和比較這兩個回歸中具有不同協變量的系數,有沒有辦法自動找到最佳擬合並對齊兩個 ggplots 的軸?
非常感謝!
你可以facet_wrap
:
library(tidyverse)
dfplot1 <- data.frame(coef=c(0.05,0,0.1,0.15,0.2),
se=c(0.1,0,0.1,0.1,0.1),
period=1:5)
dfplot2 <- data.frame(coef=c(0.05,0,0.12,0.18,0.24),
se=c(0.12,0,0.12,0.12,0.12),
period=1:5)
df <- bind_rows(dfplot1, dfplot2, .id = "id")
df |> ggplot(aes(period, coef)) +
geom_point() +
geom_segment(aes(xend = period, y = coef - 1.96 * se, yend = coef + 1.96 * se)) +
labs(x = "Year", y = "Coefficients") +
geom_hline(yintercept = 0, linetype = "dashed") +
facet_wrap(~id) +
theme(panel.background = element_blank())
由reprex 包於 2022-05-27 創建 (v2.0.1)
這一款幾乎是一樣的! 到@Carl's+1。 他的速度更快。 在我看來,主要功能是將bind_rows
與.id
參數一起使用。 這讓我們使用id
列作為facet_wrap
並且我們可以獲得一個共同的 y 軸:
bind_rows(list(dfplot1 = dfplot1, dfplot2 = dfplot2), .id = 'id') %>%
ggplot()+
geom_point(aes(x=period, y=coef))+
geom_segment(aes(x=period, xend=period, y=coef-1.96*se, yend=coef+1.96*se))+
geom_segment(aes(x=period, xend=period, y=coef-1.96*se, yend=coef+1.96*se))+
labs(x='Year', y='Coefficients')+
geom_hline(yintercept = 0, linetype = "dashed")+
theme(panel.background = element_blank())+
facet_wrap(.~id)
