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:绘制字体指南



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?

  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 (y = y1,color =Taux selon DEF),y1,y2)

ggplot(data1,aes(x = x))+
geom_line ,size = 0.61,color =black)+
geom_line(aes(y = y2,color =Taux selon EC),size = 0.61,color =black,linetype =dashed)+
xlab(X axis lab)+ ylab(Y axis lab))+
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 device = cairo_pdf 呼叫。这个出现来解决我的问题。这样,不再需要使用 embed_fonts()

I have been using the following guide to export plots made with ggplotto 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")

解决方案

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().
