我对每个图使用的代码是：

HP_specifikationer_model1 <- ggplot(Svar_spec_data)+geom_hline(yintercept=0)\ngeom_line(aes(y=HP1, x=kvartaler, color = "HP-BNP-KRE-REN")) +\ngeom_line(aes(y=HP2, x=kvartaler, color = "REN-KRE-HP-BNP")) +\ngeom_line(aes(y=HP3, x=kvartaler, color = "BNP-KRE-REN-HP")) +\ngeom_line(aes(y=HP4, x=kvartaler, color = "KRE-HP-REN-BNP")) +\ngeom_line(aes(y=HP5, x=kvartaler, color = "BNP-KRE-HP-REN")) +\ngeom_line(aes(y=HP6, x=kvartaler, color = "BNP-REN-HP-KRE")) +\ngeom_line(aes(y=HP7, x=kvartaler, color = "REN-HP-BNP-KRE")) +\nscale_color_manual(name=\'Specifikation\',\n                 breaks=c(\'HP-BNP-KRE-REN\', \'REN-KRE-HP-BNP\', \'BNP-KRE-REN-HP\',\n                          \'KRE-HP-REN-BNP\', \'BNP-KRE-HP-REN\', \'BNP-REN-HP-KRE\',\n                          \'REN-HP-BNP-KRE\'),\n                 values=c(\'HP-BNP-KRE-REN\'=\'red\', \'REN-KRE-HP-BNP\'=\'blue\', \'BNP-KRE-REN-HP\'=\'green\',\n                          \'KRE-HP-REN-BNP\'=\'cyan\', \'BNP-KRE-HP-REN\'=\'lightpink\', \'BNP-REN-HP-KRE\'=\'orange\',\n                          \'REN-HP-BNP-KRE\'=\'black\'))+\nlabs(title = "Varrierende SVAR matricer ved st\xc3\xb8d til Boligpriserne", x="Lag (M\xc3\xa5neder)", y="Respons fra boligprisen", caption = "Egne beregninger", color= T)+\ntheme(legend.position="right") + theme(panel.grid.minor.x = element_blank()) …
