ggplot2為什么我的geom_text字體看起來很糟糕

我正在用 ggplot2 制作條形圖。出于某種原因，使用 geom_text 創建的字體看起來與其他字體非常不同。它看起來“更糟”，有點像像素，當我將 pdf 粘貼到 ppt 演示文稿中時，您幾乎看不到 geom_text 文本。軸字體看起來很棒。
任何幫助表示贊賞，

  ggplot(OECD_CDNpercap_tot_aveplsGDP_select, aes(x=Country,mean, y=mean, 
                                                  label=paste(round(mean),"(",round(mean_GDPP),"% )")))  
    geom_col(stat='identity', aes(fill=Can))   
    geom_hline(yintercept=G20_mean,linetype="dashed") 
    geom_hline(yintercept=G7_mean,linetype="dashed") 
    scale_fill_manual(values=c("red","grey"))   
    geom_text(color="black",size=4,hjust=-0.05)  #hjust 
    geom_text(aes(0,G20_mean,label =paste("G20 ave",round(G20_mean))), size=4,vjust=-1,hjust=-0.22) 
    geom_text(aes(0,G7_mean,label =paste("G7 ave",round(G7_mean))), size=4,vjust=-5,hjust=-0.2) 
    labs(fill="Country") 
    ylab("per capita spending CDN$ (% of GDP)") 
    ylim(0,17000) 
    xlab("") 
    coord_flip() 
    guides(fill=FALSE) 
    theme_bw() 
    theme(axis.text = element_text(size = 12),axis.title = element_text(size = 12))

如果你愿意，這是我的資料。

uj5u.com熱心網友回復：

它為資料中的每一行過度繪制。設定check_overlap = TRUE在里面geom_text()，或者annotate改用。或者為該圖層創建一個單獨的資料框，每個標簽一行。
