为什么我的轴+图例会断开，并且每个数据集的标签显示不同

Question

我的数据包含在Excel工作簿中，对于每张工作表（~30 +），我试图创建如下图所示的图表。

我使用Rstudio并导入一张工作表，然后运行代码并保存图表，然后加载下一张工作表并重复。

我的y轴断点并不是在每个单独的图表上显示相同的，在某些＆＃34; show＆＃34;标签不会出现，而在其他标签中则出现。

至于传奇中断，每个单独的图表的持续时间不同，我想设置一个统一的图例，但似乎无法设置中断

    #cbbPalette <- c("#000000", "#E69F00", "#56B4E9", "#009E73", "#F0E442", "#0072B2", "#D55E00", "#CC79A7")

ggplot(data = Consolidated_Cadiz_prestartGB_p01, aes(x=Fix8, y=AOI, color = Duration)) +
  geom_point(alpha=0.5) +
  scale_colour_gradientn(colours = rainbow(10) ) +
  #scale_colour_manual(values=cbbPalette) + ----- not working
  geom_line(color = "grey") +
  xlab("Fixation number") +
  ylab("Area of interest") +
  labs(colour = "Duration (ms)") +
  # "show" label isnt appearing on all graphs
  scale_y_continuous(breaks = c(1:23, 25),
                     labels = c("show", "Bow", "Mast", "Boom", "Control lines", "Watch", "Wind indicator", "Sail", "Window", "Tell-tales", "Laser other", "Opponent", "Stern-opponent", "Sea", "Sea2", "Stern-sea", "Stern-sea2", "Non-laser boat", "Sky", "Other", "Coaches boat", "Pin buoy", "Committee boat buoy", "No cursor")) +
  #scale_shape_discrete(breaks=c(99, 500, 1000, 1500, 2000),
                       #labels=c("100", "500", "1000", "1500", "2000+")) + --not working
    theme(panel.grid.major = element_blank(),
        panel.grid.minor = element_blank(), 
        panel.background = element_blank(),
        axis.line = element_line(colour = "black")
  )

编辑：

> dput(head(Consolidated_Cadiz_prestartGB_p01))
structure(list(Fix8 = c(1, 2, 3, 4, 5, 6), AOIcode = c("sea2", 
"pinBuoy", "sea", "pinBuoy", "noCursor", "controlLines"), Duration = c(100, 
198, 563, 1059, 166, 298), AOI = c(15, 22, 14, 22, 25, 5)), .Names = c("Fix8", 
"AOIcode", "Duration", "AOI"), row.names = c(NA, -6L), class = c("tbl_df", 
"tbl", "data.frame"))

编辑2：Y轴问题已解决，现在需要设置图例
