问题描述
我一直在使用下面的指南将 ggplot
制成的图表导出为pdf格式:
它提出了一些字体的底部不应该出现的问题,这发生在我的例子下面。显示正确,而在Calibri中的文本显示正确。
有没有人找到解决这个问题的方法?

colnames(data1)< -c(x (y = y1,color =Taux selon DEF),y1,y2)

annotate(text,x = 1,y = 4,label =这里有一些文字 = 2,family =Bauhaus 93)+
注释(text,x = 4,y = 1,label =这里有更多文字,size = 2,family =Calibri)+
theme_bw()+ theme(legend.title = element_blank(),
legend.key = element_rect(fill = NA),
panel.border = element_blank(),
axis.line = element_line(color =black,size = 0.25),
轴。 ticks = element_line(size = 0.25),
panel.grid.major = element_line(color =grey80,size = 0.25),
panel.grid.minor = element_line(color =grey80, size = 0.25),
axis.text.x = element_text(size = 5.5,lineheight = 0.9,hjust = 0.5,family =Bauhaus 93),
axis.text.y = element_text(size = 5.5,lineheight = 0.9,vjust = 0.5,family =Calibri),
axis.title.y = element_text(size = 6.1,angle = 0,vjust = 0.975,face =bold Calibri),
axis.title.x = element_text(size = 6.1,angle = 0,vjust = -0.20,face =bold,family =Calibri))+
scale_x_continuous expand = c(0,0),limits = c(0,5))+
scale_y_continuous(expand = c(0,0),limits = c(0,10))+
ggtitle(Title)+
ggsave(Test.pdf,width = 7,height = 5)
Sys.setenv(R_GSCMD = C:/ Program Files(x86)/PDF24/gs/bin/gswin32.exe)
embed_fonts(Test.pdf)
尝试向 ggsave()添加
呼叫。这个出现来解决我的问题。这样,不再需要使用 device = cairo_pdf
embed_fonts()
。
请参阅 mgaudet 这里的评论:
I have been using the following guide to export plots made with ggplot
to pdf: plot fonts guide
It raises the issue at the bottom of the post of some fonts not appearing as they should, which happens in my example below. The text in font Bauhaus 93 appears correctly whilst the text in Calibri is displayed incorrectly.
Has anyone found a way to resolve this issue?
library(ggplot2)
library(plyr)
library(grid)
library(gridExtra)
library(extrafont)
data1<-as.data.frame(1:5)
data1[,2]<-as.data.frame(c(1,3,5,7,9))
data1[,3]<-as.data.frame(c(2,4,6,8,10))
colnames(data1)<-c("x","y1","y2")
ggplot(data1, aes(x=x)) +
geom_line(aes(y = y1, colour = "Taux selon DEF"), size=0.61, colour="black") +
geom_line(aes(y = y2, colour = "Taux selon EC"), size=0.61, colour="black", linetype="dashed") +
xlab("X axis lab") + ylab("Y axis lab)") +
annotate("text", x=1, y=4, label="Some text here", size=2, family="Bauhaus 93") +
annotate("text", x=4, y=1, label="More text here", size=2, family="Calibri") +
theme_bw() + theme(legend.title = element_blank(),
legend.key = element_rect(fill=NA),
panel.border = element_blank(),
axis.line = element_line(colour="black", size=0.25),
axis.ticks = element_line(size=0.25),
panel.grid.major = element_line(colour = "grey80", size=0.25),
panel.grid.minor = element_line(colour = "grey80", size=0.25),
axis.text.x = element_text(size=5.5 , lineheight=0.9, hjust=0.5, family="Bauhaus 93"),
axis.text.y = element_text(size=5.5 , lineheight=0.9, vjust=0.5, family="Calibri"),
axis.title.y = element_text(size=6.1, angle=0, vjust=0.975, face="bold", family="Calibri"),
axis.title.x = element_text(size=6.1, angle=0, vjust=-0.20, face="bold", family="Calibri")) +
scale_x_continuous(expand = c(0, 0), limits=c(0,5)) +
scale_y_continuous(expand = c(0, 0), limits=c(0,10)) +
ggtitle("Title") +
ggsave("Test.pdf", width=7, height=5)
Sys.setenv(R_GSCMD = "C:/Program Files (x86)/PDF24/gs/bin/gswin32.exe")
embed_fonts("Test.pdf")
Try adding device=cairo_pdf
to the ggsave()
call. This appears to solve the problem for me. This way, it's no longer necessary to use embed_fonts()
.
