【问题描述】:
当我有大量数据绘制缺失日期时,如何将刻度轴 X 调整为.integer。
我正在使用的代码是下一个(@Stefan 帮助我):
#SET OF DATA
df <- read.table(text="
Fecha - T - Tmin - Tmax
2015-07-01 - 11,16 - 7,3 - 17
2015-07-02 - 11,49 - 8 - 17,1
2015-07-03 - 11,2 - 8,8 - 15,8
2015-07-04 - 11,20 - 8,6 - 16
2015-07-05 - 11,23 - 8,9 - 15,7
2015-07-06 - 10,40 - 7,7 - 15,4
2015-07-07 - 10,10 - 8,1 - 14,8
2015-07-08 - 10,04 - 7,3 - 15,4
2018-01-01 - 11,08 - 4,9 - 17,8
2018-01-02 - 11,40 - 4,2 - 16,3
2018-01-03 - 9,000 - 5,5 - 13,5
2018-01-04 - 8,584 - 6 - 12,8
2018-01-05 - 8,679 - 7,3 - 11,9
2018-01-06 - 8,75 - 6,8 - 13
2018-01-07 - 9,33 - 6,4 - 15,2
2018-01-08 - 9,63 - 6,3 - 13,9
", header = TRUE, dec = ",")
初始代码
mmp1 <- df[,!grepl("^X", names(df))]
mmp1$Fecha <- as.Date(mmp1$Fecha)
library(ggplot2)
library(scales)
library(dplyr)
library(tibble)
mmp2 <- mmp1 %>%
mutate(
year_fecha = as.character(lubridate::year(Fecha)),
Fecha2 = format(Fecha, "%d-%m"),
Fecha2 = forcats::fct_reorder(Fecha2, Fecha)) %>%
arrange(Fecha) %>%
rowid_to_column(var = "Fecha3")
# Put the theme code aside
polish <- theme(text = element_text(size=11)) +
theme(axis.text.x=element_text(angle=45, hjust=1))+
theme(plot.title = element_text(hjust = 0.5))+
theme(panel.background = element_rect(fill = 'white', colour = 'white', size = 1.2, linetype = 7))+
theme(text=element_text(family="arial", face="bold", size=12))+
theme(axis.title.y = element_text(face="bold", family = "arial", vjust=1.5, colour="black", hjust = 0.5, size=rel(1.2)))+
theme(axis.title.x = element_text(face="bold", family = "arial", vjust=0.5, colour="black", size=rel(1.2)))+
theme(axis.text.x = element_text(family= "sans",face = "plain", colour="black", size=rel(1.1)))+
theme(axis.text.y = element_text(family= "sans",face = "plain", colour="black", size=rel(1.1)))+
theme(axis.line = element_line(size = 1, colour = "black"))+
theme(legend.title = element_text(colour="black", size=12, face="bold", family = "arial"))+
theme(legend.key = element_rect(fill = "white"))
# Simple and prefered solution: Facet by e.g. by year
w1 <- ggplot(data = mmp2) +
geom_line(mapping = aes(x = Fecha, y = Tmin, colour="Min"), size=0.71) +
geom_line(mapping = aes(x = Fecha, y = T, colour="P"), size=0.71) +
geom_line(mapping = aes(x = Fecha, y = Tmax, colour="Max"), size=0.71) +
scale_x_date(date_breaks = "1 day", date_labels = "%d-%m", expand = (c(0.001,0.008)))+
scale_y_continuous(breaks=seq(-4, 28, 2), limits = c(1,18), expand=c(0,0)) +
scale_colour_manual(name="Leyenda",
values=c(Min="green", P="#56B4E9", Max="Red")) +
ylab("Temperatura (C)")+
xlab("Tiempo") +
guides(colour=guide_legend(order = 2),
shape=guide_legend(order = 2)) +
facet_wrap(~year_fecha, scales = "free_x") +
polish
w1
第一个结果是:
# Hacky solutions with some manual labelling
labs <- select(mmp2, Fecha3, Fecha2) %>%
tibble::deframe()
date_lab <- function(x) {
labs[as.character(x)]
}
# Draw the data as one continuous line
w2 <- ggplot(data = mmp2) +
geom_line(mapping = aes(x = Fecha3, y = Tmin, colour="Min"), size=0.71) +
geom_line(mapping = aes(x = Fecha3, y = T, colour="P"), size=0.71) +
geom_line(mapping = aes(x = Fecha3, y = Tmax, colour="Max"), size=0.71) +
scale_x_continuous(breaks = as.integer(names(labs)), labels = date_lab, expand = (c(0.001,0.008))) +
scale_y_continuous(breaks=seq(-4, 28, 2), limits = c(1,18), expand=c(0,0)) +
scale_colour_manual(name="Leyenda",
values=c(Min="green", P="#56B4E9", Max="Red")) +
ylab("Temperatura (C)")+
xlab("Tiempo") +
guides(colour=guide_legend(order = 2),
shape=guide_legend(order = 2)) +
polish
w2
第二个结果是:
使用相同的代码但绘制大量数据我遇到了这个问题:
如何调整这个 axix X? 谢谢。

将您的 x 轴转换为
Date,然后使用scale_x_date来控制中断和标签。请参阅以下示例:stackoverflow.com/a/50710428/786542 & stackoverflow.com/q/56811184/786542 -
不,不可能,因为在代码的最后一部分,是其他格式。

嗨约翰_埃里克。第一的。如果他们帮助您解决问题,请将答案标记为已接受。第二。问第二个问题时:不要在帖子中粘贴答案,只需在帖子中添加指向第一个问题/答案的链接。第三。您可以简单地要求我帮助您解决第二个问题,而不是发布第二个问题。由于我已经熟悉问题和答案,因此调整我的答案可能要容易得多。第四。看我对第二个问题的回答。 (:

非常感谢 Stefan,您的帮助很大。我是这个平台和 R 编程的新手,有些东西我不知道。我在第一个问题或问题中做了这个问题,但版主删除了我的问题两次,因此我不得不再次提问。谢谢你,我会把你的建议付诸实践。
