问题描述
我的 x 轴使用 Lubridate 包格式化为日期。
我已尝试使用 xlim 和breaks 的不同选项,但似乎无法将“2020”放入图中。
interest_exp_line <- ggplot(interest_exp_df,aes(x = year,y = value,colour = country_name,group = country_name)
)
interest_exp_line2 <- interest_exp_line +
geom_line() +
geom_hline(yintercept = 0)
interest_exp_line3 <- interest_exp_line2 +
bbc_style() +
scale_x_date(date_labels = "%Y") +
theme(axis.title.x = element_text(size = 12),axis.title.y = element_text(size = 12)
) +
labs(title = "Is Ghana the next Zambia?",subtitle = "Ghana isn't getting any better...",x = "Year",y = "Interest payments\n(% of expenses)")
finalise_plot(plot_name = interest_exp_line3,source = "Source: World Bank",save_filepath = "c:/workspace/repos/world_bank_data/outputs/figures/ghana_zambia_interest_line.png",width_pixels = 640,height_pixels = 450
)
我的情节是这样的:
解决方法
我现在才知道...
它与音阶无关,需要进行主题调整。我通过使用 plot.margin = margin(10,15,10,10)
