为什么会使用GGPLOT2出现我的字幕和字幕？

Question

我目前正在制作一些地块，显示纽约州长岛各个城镇中最常见的行业。除了我似乎无法将我想要的字幕或字幕带入最后的绘图外，该剧情本身看起来几乎完全是我想要的。这是我正在使用的代码：

    hemp_occ_plot <- ggplot(aes(x = occ_cat, y = count), data = occ_hempstead)+
  geom_bar(stat = "identity", fill =c("#84D6B8", "#B8574D", "#B03B70", "#5AA197", "#21262A", "#724B65", "#772684", "#052A7F",  "#D08F70", "#A3B2D8", "#4B1F28", "#CEC67E", "#FE8EA4"))+
  ggtitle(label = "Most Common Industries Among Hemsptead Workers", subtitle = "Showing 408,460 Civilian Workers")+
  labs(x = NULL,
       y = "Workers per Industry", 
       caption = "Source: ACS, 2019")+
  theme(plot.title = element_text(family = "Arial", face = "bold", size = (15), hjust = -1, vjust = 0),
        plot.subtitle = element_text(family = "Arial", size = (12), hjust = -1, vjust = 0),
        axis.title.x = element_text(family = "Arial", size = (12), vjust = 1),
        axis.text.x = element_text(family = "Arial", size = (10)),
        axis.title.y = element_text(family = "Arial", size = (12)))+
  scale_x_discrete(limit = c("Agriculture_etal","Construction","Manufacturing","Wholesale_Trade","Retail_Trade","Transportation_Utilities","Information","Finance_Insurance_Realty","Professional","Eds_and_Meds","Entertainment_Hospitality","Other","Public_Administration"),
                   labels = c("Agriculture, Forestry, Fishing, Hunting, and Mining",
                              "Construction",
                              "Manufacturing",
                              "Wholesale Trade",
                              "Retail Trade",
                              "Transportation, Warehousing, and Utilities",
                              "Information",
                              "Finance, Insurance, Real Estate, Rental  and Leasing",
                              "Professional, Scientific, and Waste Management",
                              "Education, Health Care, and Social  Assistance",
                              "Arts, Entertainment, and Hospitality",
                              "Other Services, Except Public Administration",
                              "Public Administration"))+
  coord_flip()

这就是图的外观：

您应该更改主题（plot.title，plot.subtitle）调用中的设置。来自Datanovia网站： https://www.datanovia.com/en/blog/blog/ggplot-title-subtitle-subtitle-subtitle-and-caption/#:~: text = the ％20DEFAULT％20GGPLOT％20个title％20 alignment，element_text（hjust％20％3D％200.5））％20。

    hjust and vjust: number in [0, 1], for horizontal and vertical adjustment of titles, respectively.
    hjust = 0.5: Center the plot titles.
    hjust = 1: Place the plot title on the right
    hjust = 0: Place the plot title on the left

不建议在[0,1]外使用hjust或vjust值。
