我得到了以下有關厄瓜多爾 GDP 增長和 IMF 預測的資料。
我想做一個圖表，從2015年到2021年是一條線（geom_line），但從2022年到2026年是一條虛線，我希望這表明2022年是預測。
這是我的代碼，但我不知道如何說明條件。
forecast %>%
filter(Year >= 2015L & Year <= 2026L) %>%
ggplot()
aes(x = Year, y = `Real GDP Growth`)
geom_line(size = 0.75, colour = "#B22222")
labs(x = "Year", y = "GDP Growth", title = "Ecuador's Real GDP growth Forecast", subtitle = "Forecast done by the World Economic Outlook")
theme_light()
theme(plot.title = element_text(size = 18L, face = "bold", hjust = 0.5), plot.subtitle = element_text(size = 13L,
hjust = 0.5), axis.title.y = element_text(size = 13L, face = "bold"), axis.title.x = element_text(size = 13L,
face = "bold")) scale_x_continuous(n.breaks=11) geom_hline(yintercept = 0, lty=5, size=0.75)
這是資料：
structure(list(Year = c(1980, 1981, 1982, 1983, 1984, 1985, 1986,
1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997,
1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008,
2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019,
2020, 2021, 2022, 2023, 2024, 2025, 2026), `Real GDP Growth` = c(4.9,
3.9, 1.2, -2.8, 4.2, 4.4, 3.1, -6, 10.5, 0.3, 3, 5.1, 3.6, 2,
4.3, 2.3, 1.7, 4.3, 3.3, -4.7, 1.1, 4, 4.1, 2.7, 8.2, 5.3, 4.4,
2.2, 6.4, 0.6, 3.5, 7.9, 5.6, 4.9, 3.8, 0.1, -1.2, 2.4, 1.3,
0, -7.8, 2.8, 3.5, 2.5, 2.6, 2.8, 2.8)), class = c("tbl_df",
"tbl", "data.frame"), row.names = c(NA, -47L))
最終圖形應如下所示：
在此先感謝您的幫助。
uj5u.com熱心網友回復：
試一試 - 我將您的資料分為兩組用于兩種線型別，并對其余部分進行了一些重組和簡化：
ggplot()
aes(x = Year, y = `Real GDP Growth`)
geom_line(data = filter(forecast, Year <= 2021), size = 0.75, colour = "#B22222")
geom_line(data = filter(forecast, Year >= 2021), size = 0.75, colour = "#B22222", linetype = "dotted")
labs(
x = "Year", y = "GDP Growth",
title = "Ecuador's Real GDP growth Forecast",
subtitle = "Forecast done by the World Economic Outlook")
scale_x_continuous(n.breaks = 11)
geom_hline(yintercept = 0, lty = 5, size = 0.75)
theme_light()
theme(
plot.title = element_text(size = 18L, face = "bold", hjust = 0.5),
plot.subtitle = element_text(size = 13L, hjust = 0.5),
axis.title = element_text(size = 13L, face = "bold")
)
